Question about PC Desktops

1 Answer

Power/Startup Fail Hi there. My HP a6040a is almost 2 years old, with no problems except needing a new graphics card, until now. It just will not turn on. We've checked all cords, unplugged and rested capacitors etc etc, but no luck. The power supply light (green LED) is on fine, and the monitor is fine, but the blue light on top of the tower refuses to come on. Any ideas? Cheers, Beth.

Will this graphics card work with my computer?


1) HP xw6200 Workstation desktop computer,

http://h18000.www1.hp.com/products/quickspecs/11975_div/11975_div.HTML

Power Supply: Maximum rated Wattage - 500 Watts.

XFX ATI Radeon HD5750 graphics card,

http://www.ebay.co.uk/itm/2GB-ATI-Radeon-HD-5750-1GB-HDMI-1080p-BluRay-EyeFinity-Gaming-Graphics-Card-/120973408169?pt=UK_Computing_Computer_Components_Graphics_Video_TV_Cards_TW&hash=item1c2a93b7a9&_uhb=1#ht_4735wt_1080

Yes.


1) Install the software F-I-R-S-T, then physically install the graphics card.
Windows running, put the Installation disk that comes with the graphics card, into the CD/DVD drive.
Load all software. The drivers, and Catalyst Control Panel.

Windows will NOT use the software until the graphics card is installed, so don't worry about not having graphics in the meantime.

2) Computer unplugged from power FOLLOW Anti-Static Precautions.

Anti-Static Precautions:
Your body carries Static electricity. Static WILL fry out (Short Circuit), the delicate hardware components inside a computer.

Relieve your body of Static BEFORE reaching inside your computer, AND before removing any parts out of their anti-static bags, or cartons.

Computer on a table, computer unplugged from power, computer case open;
TOUCH an unpainted surface, of the metal frame of the open computer case.
This action will relieve your body of Static.

IF you leave your computer in the middle of working on it, be SURE to Touch the metal frame again upon your return.

3) Physically install the graphics card.
(The Lock Lever on the PCI-Express x16 slot, goes UP to install a graphics card, or to remove a graphics card. It looks as though you should push down on it)

http://www.txcesssurplus.com/servlet/the-9225/HP-408544-dsh-001-xw6200-WorkStation/Detail

Looking at the black PCI-Express x16 slot, with it's green Lock Lever, it looks as though there should be room for the graphics card.

Looking to the right of the green Lock Lever, look at the 4 gold colored Choke Coils. It may be tight, but the graphics card should clear the first two.

Areas of concern, though;

1) Power Supply:
The XFX Radeon HD5750 graphics card, requires a minimum of a 400 Watt Power Supply.

The graphics card doesn't use 400 Watts, of course. This is the minimum power requirement by the graphics card manufacturer, and based on the power the card needs, and the rest of the computer.

XFX, just like all graphics card manufacturers, uses a computer system set up to the maximum, for a test unit.

Gamer style motherboard.
Powerful Processor, that is probably a dual core, or quad core.
Maximum amount of ram memory.
Two optical drives
Two or more computer case fans.
Two or more harddrives.

You get the picture.

Power consumption has to be based upon what each individual hardware component will use, AND the graphics card.

Power Supply:
Problem is, the computer has some age on it. From searching it seems to have been made in 2004. Makes it 8 years old now.
Makes that Power Supply 8 years old now too.

A) Pre-built computer manufacturers, such as HP, Gateway, Lenovo, Toshiba, etc., have their components made by someone else.
The Power Supply is one such component.

Usually a generic Power Supply manufacturer, such as Bestec, or HiPro, or Delta, for HP computers.
Low quality electronic components are used in these power supply's.

Isn't a big deal usually, until you start to tax the limit on the Power Supply, such as installing a powerful graphics card.

Power Supply manufacturers also had a great tendency, to overate their Power Supply's back in the day. Made the Power Supply sell better, 'fudging' the actual Wattage rating.

Wattage was actually more like 60 to 70 percent, of what was stated.
300 Watts (60 percent) to 350 Watts (70 percent) is more actual.

The XFX ATI Radeon HD5750 also requires a 6-pin PCI-Express power cable, coming from the Power Supply, and connected to it.

The maximum amount of Wattage a PCI-Express x16 slot can deliver, is 75 Watts.
The 6-pin PCI-Express power cable delivers an additional 75 Watts,

http://www.playtool.com/pages/psuconnectors/connectors.html#pciexpress

"This cable is used to provide extra 12 volt power to PCI Express expansion cards.
PCI Express motherboard slots can provide a maximum of 75 watts.

Many video cards draw significantly more than 75 watts, so the 6 pin PCI Express power cable was created.
These high-power cards draw most of their power from the 12 volt rail so this cable provides only 12 volts."

(Yellow wires are 12 Volt wires. Red wires are 5 Volt wires, Orange wires are 3.3 Volts. All are DC voltage. Black wires are Ground wires)

Will your Power Supply have a 6-pin PCI-Express power cable?
I doubt it.
In the Playtool link, see the 6-pin PCI-Express adapter power cable, shown on the right?

Takes TWO 4-pin Peripheral power cables,
(Commonly misnomered as a 'Molex' power cable),

http://www.playtool.com/pages/psuconnectors/connectors.html#peripheral

If you are going to use one of these power adapter cables, you NEED TWO 4-pin Peripheral power cables!

HAS to have TWO Yellow 12 Volt wires going to it.

Will using a 6-pin PCI-Express adapter power cable, and One 4-pin Peripheral power cable work?
Most of the time yes.

PROBLEM is,
Over time the;

1) PCI-Express x16 slot contact pins -> BURN

2) Gold plated contact pins on the bottom of the graphics card -> BURNS

3) Connection on graphics card for the 6-pin PCI-Express power cable - BURNS

4) 6-pin PCI-Express power cable's connector -> BURNS

No if's, and's, or but's; it WILL happen.
Result is usually throw the motherboard away, and the graphics card.

So you may be looking at getting a better Power Supply.
Here is one example that will work,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=899124&CatId=1483

A) 600 Watts. Gives you an additional 100 Watts of power. Less strain on the Power Supply.

B) 120mm fan. A larger fan turns slower, therefore makes less noise.
Puts out more air flow than an 80mm fan, even though it turns slower.

C) Has all the power cables required, plus more.

D) Has TWO 12 Volt power rails.
12 Volt 1 is capable of 23 Amp's.
12 Volt 2 is capable of 20 Amp's.
Total combined Amperage for the two 12 volt power rails is 43 Amp's.

Gamer computer?
Not IMHO. Uses ECC ram memory.

That is Error Correcting Control ram memory. The ram memory runs the data through it twice, in order to make sure everything is correct, before using the data.
This is the type of ram memory a Server computer uses.

Could be wrong, and it could be used as a gamer computer, though. We will see when you are done, IF this is the intent.

[ http://en.wikipedia.org/wiki/ECC_memory

Reasons for not using ECC:
"A performance decrease of around 2-3 percent, depending on application, due to the additional time needed for ECC memory controllers to perform error checking;"

Dear PC Experts, I have a computer HP Pavilion m9300t and have been using three years already. The problem occurs about 4 months ago. When I turned on my computer, it looks fine in the beginning. As I...


It's probably the graphics card. They are one of the most common items to go bad over time. You could try to open your computer and blow out the dust from the video card, the CPU, the Fans, the Power Supply, and any other area you see dust collecting. You'll want to unplug the unit and take it outside to do this. Also, if you have more than one port on the back that will take the monitor cable, try plugging the monitor into that to see if that works. (some machines have a video card in a PCI slot as well as a built in video port... if the PCI card is bad, the built in port could still work).

How do i replace the graphics card/ motherboard in my hp G60-121WM. Need disassembly steps


1 . Before beginning any work on your computer, be sure to turn it completely off and then remove all connected cords or cables.

2 . To get to the old graphics card the side panel of your computer's case must be removed. Most cases will have two screws that must be taken out at the top and bottom of the panel. Some cases will alternately have a twist off knob on the side instead of screws that simply needs to be turned several times until the panel slides off.

3 . Once the panel is removed it is time to take out the old graphics card. The card will typically be held in place by a single screw connected to the case. Remove this screw and then simply pull the card straight out.

4 . The new card is installed easily by pushing it into the correct slot on your motherboard and then putting the screw back in place. Depending on your motherboard, the card will either be connected to a PCI, PCI Express, or AGP card slot. The slots do not change the way that the card is installed, but it is important to make sure you have the correct type of card for the correct slot. A PCI card will not fit in an AGP slot and vice versa.

5 . Place the side panel back on your computer's case and re-attach the screws or turn the twist knob until snug. Plug back in any cords or cables that were removed and power your computer back on.

6 . A new graphics card will need to have drivers installed so that it works properly with your operating system. If your graphics card came with a CD, insert the CD into your computer and follow the on screen prompts to install the software. If your graphics card did not come with a CD then Windows may prompt you automatically to search for drivers to install


Hope the above information will be helpful to you.
Thanks.

I have an HP Pavilion a706n PC and I just replaced my old monitor with a new LG E2040 monitor. I need to upgrade my video card and don't know what I can or should upgrade to.


If the existing graphics card works with your new monitor, there isn't need to upgrade the graphics card unless you have a specific need such as a graphics intensive games program that doesn't work with the old graphics card.

Hi. I was buying HP Pavilion slimline 5310sc and want to put a new graphic card in it, to play games. What cards would fit best? Bjarki


Graphics cards are of many companies. For my opinion, Ge-force and N-vidia graphics cards are best. 512 mb graphics cards are well for playing games. As your need of gaming, buy high capacity graphics card as 1 gb or 2 gb.

I have an HP Pavilion a1777c with a blank monitor


If the computer is starts up normally other than the no-video problem (that is, you hear all the normal sounds from the computer and the usual Windows startup music), then you probably do need a new video card. According to HP's spec page for the motherboard used, you'll need a PCI-E video card. Don't confuse this with a regular PCI card which has a different connector.

The spec page also says the board has integrated graphics. so you could remove any video card that's been installed and try booting with the built-in video. If everything else is working properly you can use that until you get a new expansion video card.

If the trouble is that the computer's not booting at all even though it's coming on, you'll need to figure out why. This might be a memory or video problem, although these usually cause some beep code if the motherboard gets into its POST (power on self-test). If nothing at all happens, this is often the sign of a bad power supply, processor chip or system board.
