Question about HEWLETT-PACKARD Pavilion p6520f PC Desktop

1 Answer

HP p6520f: onboard graphics died. Installed what should have been a compatible GPU. PC powers on but still no display; also, none of the USB ports work. PSU that came with the PC is only 250 watts.

The PSU could be contributing to the issue, but I would think that the PC would either not boot at all or shut itself down within a few minutes. The GPU is a Zotac GeForce GT630 ZONE Edition with 1 gb of 64 bit, GDDR3 on board, no external power coupling. Please help.

SOURCE: When I plug the unit into power, the CPU fan runs very fast but no boot,

Sounds like you are overheating. One way to tell if it's overheating is you say it will run for about 30 minutes then shuts down. When it shuts down try rebooting to see if the boots successfully. If it fails to boot successfully right after it shut down then you are probably overheating. If you wait awhile to let it cool down for 30 minutes or so and if you reboot and it does it successfully you definitely have a overheating problem. If I remember correctly all those compaq sr series have loud and fast running fans. Computers overheat because of three reasons for the most part: 1) A fan has stopped working. 2) The Thermal Paste on the CPU and Heat Sink has dried up or is not thick enough to keep the unit cool. 3) Dust has clogged the fan vents and inside the computer. Fortunately for you desktops don't have to be completely disassembled like laptops to get to the fan, CPU and heatsink. Just pop the case and you'll see the components attached to the motherboard

Testimonial: "Thanks. I cleaned out the dust and loaded CoreTemp.exe. The system stayed running through the programs that caudsed shutdown before - even though RealTemp.exe did not report a problem. So the system works, except that when I press the power button I still get the fast running fans instead of shutdown. I still have to pull the plug for shutdown.. I'll live with that."

SOURCE: i have installed two diferent graphics card, #1 was MSI 5459 and #2 was a Nvidia GeForce 250. Bth ran fine afor a short period of tme #1 for a month an #2 for about 2 weeks. After these periods of

I don't find the MSI 5459 graphics card, William.
Am familiar with the Nvidia GeForce 250 GTS, though.

Using the GeForce GTS 250 as an example, the graphics card requires a 6-pin PCI-Express power cable, for additional power, along with the power it gets from the PCI-Express x16 slot it is in.

The unit is furnished with an adapter power cable, that converts 2 Molex power cables, (4-pin Peripheral power cables, actually), into 1 PCI-Express 6-pin power cable.

Note that the 6-pin PCI-Express power cable, has two Yellow wires in it.

Let's look at a 4-pin Peripheral power cable,

Note there is one Yellow wire, one Red wire, and two Black wires.

The Red wire is a 5 Volt wire, and not used by the adapter power cable.

The two Black wires are Ground wires, and only one is used by the adapter power cable.

The Yellow wire is a 12 Volt wire, and is used by the adapter power cable.

The 6-pin PCI-Express power cable requires TWO Yellow 12 Volt wires.
(And three Black Ground wires)

This means Two 4-pin Peripheral power cables MUST be used.

Failure to use two 4-pin Peripheral power cables, to that adapter power cable, means the GeForce GS 250 is NOT receiving enough power.

This will burn the connection at the graphics card, burn the adapter power cable connector, and burn the PCI-Express x16 slot it is sitting in.

Takes time, but will happen.

Could this be what you have done?

It also requires 150 Watts all by itself. You need more power for the rest of the computer.

(The 6-pin PCI-Express power cable is designed to provide up to 75 Watts of power. This means 75 Watts of power, also comes from the PCI-Express x16 slot, it is sitting in)

Nvidia GeForce GTS 250,

P6 2310e HP Pavilion with Windows 8.1 and MS7778 V 1.0 mb. On-board graphics fading so trying to add a new graphics card to PCIE X 16 slot.

2310ea? what is the letter after e,?
lots of pc;s made called 2310.

a 2012 PC, not old. very newest , modern UEFI
AAHD2-HY (Holly2),mobo
so is the coin cell ok, 2.9v to 3.3vdc measuare, that be first.
on all PCs with BIOS not acting right. for SURE.
did you push the help key in bios, did you try all USB slots
not all usb ports (jacks) work in BIOS, and in BIOS turn on the legacy USB settings, this helps greatly.
is the BIOS prompting in text , hit ESC/F10 to enter setup
setup = bios in HP jaron. its bios, UEFI for sure.
The newer PCs HP has auto switch on the bios change over to express Video. no wattage stated on PSU ,why?
all top speed boards made have huge power needs,
that slot in your PC (express) is only 75watts, period.
so any graphics card added that is more than that needs
the aux power port on your card used, and a match power rated PSU or better. (done this vast times)
the stock PSU is gutless worder 300watts.
ok for cheap slow onboard, GPU, no issues there.
here is your new cards spec, out of your manual.
18 Amp on the +12 volt rail.****
see that? it means 300w is marginal, (the card sucks 216w by self)
and this in same manual.
****Minimum system power requirement based on a PC configured with an Intel Core i7 3.2GHz processor."

im reading the side of your PSU now.
Va -cable 12amps
vb cable 16 amps
they do NOT ADD, if you draw, 16amps of the Vb it leaves nothing for Va.

i then look at your card, it has no 12v AUX jacks.
wow, they expect to suck 18amps 215 watts of the 75w express slot, that is crazy (hp spec and a standard on express)

there are slower cheaper cards,
if you need the speed of this card (unsaid)
then get card and PSU that match. they all work. I run GTX650.
500w pSU min, more is always better, and more gets you better quality in any PSU, top brands.

that Aside the card should work (?) at cold boot.
the screen must show , text, if not , its bad or the PSU is bad
or other reasons (lots)mybe the PSU is already bad, and made the onboard GPU fail. i have no history on this PC,
the service manual covers this? HP
see it?89bfe8fa-c622-4c40-81b3-c1fcaceffa46.jpg

Is the hp a1330n usb 3.0 compatible? Mine doesn't even have the "pci-e" mini slots for plugging in a usb 3.0 card. Is my only option is replacing the motherboard with one that has pci-e slots?

- You can use PCIe x16 slot (if using onboard graphics adapter) and PCIe/USB 3.0 card (data transfer rates up to 5 Gbit/s, i.e. 10x faster than USB 2.0).
- Or use PCI/USB 3.0 card (for legacy PCI slots to support the USB 3.0 standard), which allows data transfer rates up to 1.3 Gbit/s (3x faster than USB 2.0).

Hello here is the homepage:

To enable crossfire, you must have 2 identical graphic cards.

The onboard graphic can`t be used with the hd6670.

This means that you must buy another hd6670 to add on the mainboard.

The graphic cards homepage:

AMD CrossFire technology is the ultimate multi-GPU performance gaming platform. Unlocking game-dominating power, AMD CrossFire harnesses the power of two or more discrete graphics cards working in parallel to dramatically improve gaming performance.

You also need a large power supply min. 500 watt to have enough power.

Please disable the onboard graphic in the device manager.

Good luck

Can't install drivers for GeForce GT 430. "Graphics Adapter Not Found."

I am assuming that your PC is working alright connected to the onboard graphics port.
Make sure any supplementary power connectors to your video card are in place, and the card is firmly inserted into the PCIE slot.
If you try these two items with no results, you might try installing the card in a known working PC. It could be a problem with the card itself.

Ive installed the ati his radeon ice q graphics card and my computer will not boot,Why?

hook monitor cable back to your onboard video port then 1st make sure you have already downloaded the driver for your new graphics card. then at start up go into system setup and go to your display and make sure that you have your new graphics card enabled as your primary graphics instead of onboard video. it will say something like 1.Onboard 2. AGP/OR PCI MAKE SURE YOU DONT HAVE YOUR ONBOARD ENABLED AS YOUR PRIMARY VIDEO. AFTER THAT JUST SAVE AND EXIT THE JUST HOLD POWER BUTTON DOWN TILL PC SHUTS DOWN THEN SWITCH YOUR CABLE MONITOR CABLE FROM THE ONBOARD TO THE AGP/PCI CARD THEN RESTART YOUR PC. THEN YOUR PC WILL SAY FOUND NEW DATA AND WILL INSTALL THE DRIVER YOU HAVE DOWNLOADED FOR IT THEN YOU SHOULD BE OK IF THE CARD IS COMPATIBLE WITH THE MOTHERBOARD

Desktop monitor port not working. processor, keyboard, mouse all powered on & working, you can hear it boot up. I use this with other computers, it works fine. monitor has power but goes to sleep. Is...

Ha, no kidding!
I just had a HP Pavilion a705w come in for repair at my shop!
Small world.

Okay, let's go with your theory that the power supply is okay, and the Processor is indeed operating.

Your theory is that the GPU on the motherboard isn't working.

No Signal on the monitor means No Video Signal.

The computer isn't sending out a video signal.

(The HP Pavilion a705w comes with Integrated Graphics.

Meaning the GPU is soldered to the motherboard.
Another term for Integrated Graphics is OnBoard graphics.
On the motherBoard.

GPU stands for Graphics Processing Unit.
A GPU can be soldered to the motherboard, {Integrated Graphics}, or soldered to a dedicated graphics adapter card.

Do you have a PCI graphics card around? Still have the installation disk also?
Computer unplugged from power, and observing anti-static precautions, plug it in, screw it down to the frame.
Connect the monitor to the graphics card. Plug the computer into power.
WAIT 1 minute. Turn the computer on. You may have bad graphics because you haven't installed the drivers off of the installation CD yet, but you should have graphics.

Don't have a PCI graphics card available, or no graphics showed up on the monitor?

Okay, then humor me for a moment.
Computer unplugged from power. Anti-static precautions implemented.
Take the ram memory module/s out, and clean the gold plated contact pins with a pencil eraser.

Start at the top of the pins, and brush going down towards the bottom.

Use air to clean off the eraser 'dust', then reinstall the ram.
Plug into power, wait 1 minute, turn the computer on.

Still no?

Have another known, working power supply around, that is an ATX power supply, has at least 250 watts, and has the proper power cables?
I'd like you to use it for a test.

No spare power supply?
Do you have a multimeter?

It's time to check the power out of that power supply.

1) Orange insulated wires are 3.3 Volts
2) Red wires are 5 Volts
3) Yellow wires are 12 Volts
4) ANY Black wire is a Ground wire.

The Positive (Red) lead goes to the power wire, the Negative (Black) lead goes to a Ground wire.
Multimeter is set to the 50 Volt DC scale.

(Auto parts stores sell economically priced multimeter's for around $10 to $15)

Back to your statements in your added comment.

At first it could have been something as simple as the Ethernet card was bad, or the onboard Ethernet was bad.

However, it could be that the motherboard has another issue, and one by one, the motherboards features are going downhill.
No internet. Now no graphics.
Could be this,

I still think the first place to check is the power supply.
It's a cheap quality Bestec power supply.
The Electrolytic Capacitors seem to be the first components that fail in these power supply's.

However, if the computer was dirty inside, as well as the power supply, this could also make a power supply fail.

I've stated what a weak voltage power rail would do. Not enough power to turn the Processor on.
What I haven't stated is that the two main problems with a computer is,

1) The computer is dirty inside, as well as the power supply.
'Kills' power supply's and motherboards.

2) Power supply's are the second item. A pre-built computer manufacturer typically installs a cheap quality power supply.
Saves them money.

Bestec, HiPro, and Delta, are three power supply manufacturers HP uses a lot.
Cheap quality components are used inside.

Where do we find the display lid switch for a HP Pavilion dv9715nr ? we replaced a damaged hinge on this laptop first and now we cannot get a display.

Let me guess. Damaged Left hinge?

HP had a recall for this problem, but the recall has lapsed as of May 31, 2009.

The Pavilion dv9000 series, also has a problem with the graphics chip overheating, and burning up.

Yes, I know. Just a regular ray of sunshine.

Graphics chip:
1) Chip is a slang term for I.C.
Integrated Circuit.

2) A graphics chip is a GPU. Graphics Processing Unit.

The HP Pavilion dv9000 series of Notebook PC's use Integrated Graphics, as commonly do a very large percentage of notebook PC's.
The GPU is mounted, { Soldered }, directly to the motherboard.

{Another term for Integrated Graphics is OnBoard Graphics.
On the motherBoard}

The GPU is an Nvidia GeForce 8600M GS, that uses the PCI Express technology.

The cooling system of this laptop (Notebook) has a poor cooling design for the GPU.

This causes the GPU to overheat, and burn up.
There is no just replacing the GPU. The fix is to replace the entire motherboard.

I would like to suggest a simple test to see if the GPU is bad first., before going on to replacing the Lid Switch Module.

Hopefully it is just the Lid Switch Module, or perhaps another simple problem I will detail. My thoughts at present, are that it is another small problem.

The test requires plugging in a VGA monitor to the back of the laptop, and seeing if the graphics are good.
(CRT monitor. Looks like a small television set)
Do you have access to a VGA monitor?

[ Bypassing the Lid Switch Module requires removing these components to access it;
1) Battery
2) Harddrive
3) Optical Drive
4) Switch Cover
5) Keyboard
6) Speaker Assembly
7) Display Assembly
8) Top Cover
9) Top Cover Trim ]

On the Left side of the laptop is a VGA port, to connect the VGA monitor to.
(Example of a VGA port:

Coming from the back of the laptop on the Left side, it is the second port.

VGA monitor plugged into laptop, power on.
Hold the fn key down, tap the F4 key.
Give the VGA monitor time to, 'Come to life'.

VGA monitor comes on?

GPU is good, time to go on with the diagnoses.

The Display Cable also routes through the Left Hinge.
This cable has the graphics signal cable, and the power cable for the LCD Display.

(The Microphone Cable also routes through the Left Hinge)

This cable is very small, and could have easily been pinched, which could cause breakage of the tiny copper wires, inside the insulation sheath of the cable.

If it is pinched, this MAY be visible by observing the plastic insulation of that cable. The cable does get slightly squished with normal usage, though.

With the Left Hinge being loose, and is hard to open anyway, the cable could have become stretched.

This would cause breakage of the tiny copper wires inside, and the outside damage to the insulation of the wire, may not be so readily apparent.

It could also be that the connector that plugs into the motherboard, has simply been pulled loose, or is not tightly plugged in, and is not making a good contact.

I will include the link to the Service Manual from HP Support, in an additional comment.

I do suggest you buy, and wear an inexpensive ESD wrist s-trap, and connect the alligator clip to a good ground source.
(Average cost is around $6)

Continuity test indicates the Display Cable is okay?

( The Display Cable disconnects from the motherboard, and from the Inverter, that is located in the Display Assembly.

The Inverter is what converts power for the LCD display screen, and also the Backlight Lamp.
The Inverter is a small circuit board, located behind the Display Bezel of the Display Assembly.

Cable disconnected from the motherboard, and from the Inverter, a continuity test of the Display Cable is done with a multimeter.

The multimeter is set to the 1K, or 10K scale.
An economical, but decent enough multimeter for this type of testing, can be purchased for around $12 to $15, from a local auto parts store )

Okay, now it's time to replace the Lid Switch Module.

I will give the link to HP Support, and the Service Manual for the Pavilion dv9500, dv9600, and dv9700 series, in an additional comment so you can disassemble the laptop to access the above.

Hello i have hp rp5000 pc which have AGP port onboard but when i put graphic card in it it doesnt recognized it. I tried with another hp rp5000 bios but it doesnt work anyway-is there anysolution?

Erm, although the slot is labelled AGP1 (HEY HP Accelerated GRAPHICS Port 1 ???), it is not for a graphics card.
It is intended for an enhanced USB card that adds additional USB ports as well as 12volt and 24volt outputs.
The RP5000 was designed to be a POS (point of sale) unit and the additional ports were for devices such as barcode readers, handscanners and card readers to be plugged into.

HP Pavilion a1620n monitor won't display

If you have TWO graphics ports (one onboard + one seperate card) then double check you are plugged into the right one !

If you get the same issue with another monitor then it is more than likely that your graphics card is pooched.
If you are using the onboard then you can buy a pci express card to replace / bypass the onboard.
If you are already using a seperate graphics card you may well need mo replace it.

This is the motherboard for your machine. Remember that if you dont use the onboard graphics you should got into the bios and tell it which you want as primary dislay adapter
