Hi,, what you need to do is flash the bios there are 2 ways to do this I'll describe the two. Unplug the system and open it up.

1.) locate the jumper called jp1 or jcmos. Its currently set to 1 and 2,, set it to 2 and 3 ,, wait 10 seconds the set it back to 1 and 2

2.) locate the battery on the main board, remove it.. Its held in place by a pin, just pry it loose. press and hold the power button for 1 minute, release and press 5 times (to dump any current in the system) relpace the battery.

When the system boots you will need to enter the setup, load optimised defaults, save and exit.. Dont worry just follow the onscreen instructions to complete those steps.

My HP desktop fan turns on as does the green light, but there is a constant beeping sound and no display on the monitor


This error message mean that there isn't video signal from the video card going to the monitor.
Try reconnecting the video cable to the monitor. If this does not work then you may have a faulty video card.

So practically the pc starts but you don't have any image. Try using another monitor and another video card - one of them is dead.

WHEN I BOOT IT UP-NO VIDEO EVERYTHING IS CONNECTED BUT I CAN'T SEE ANYTHING


When a monitor displays No Signal, it is an indication that there is no video signal going to the monitor.

The monitor is working fine.

1) Could be due to a bad monitor cable. They do go bad.

Test would be to take that monitor cable, (If it disconnects), and use it on a known to be working computer.

2) Could be the graphics of the computer.

If the computer has Integrated Graphics, the test would be to install a graphics card, and plug the monitor into it.

[Integrated Graphics is also termed as OnBoard Graphics.
On the motherBoard.

The GPU is the graphics 'engine' of a computer.
Graphics Processing Unit.

It can be soldered directly to the motherboard, (Integrated Graphics), or soldered to a removable graphics card.

http://en.wikipedia.org/wiki/GPU ]

When you install a graphics card, (graphics expansion card), the Integrated Graphics is bypassed.
The monitor plugs into the graphics card, not the motherboard.

Could be wrong, but I'll bet it's the Power Supply.

If this problem directly relates to a Compaq Presario SR1550NX, the computer is 5 years old. (According to my sources)

If the computer isn't cleaned inside, and the Power Supply isn't cleaned inside, on a regular basis as needed, the Power Supply is one hardware component that is sure to fail.

It's the top problem relating to computer failure.

The cooling components for a power supply is it's fan, and Heatsink's that are used inside.

1) http://en.wikipedia.org/wiki/Switched-mode_power_supply

2) http://en.wikipedia.org/wiki/File:ATX_power_supply_interior-1000px_transparent.png

The basic physical makeup of a Heatsink is a flat plate of metal, with tall, thin fins protruding from it.

The flat plate absorbs heat from whatever it is placed against, and the tall, thin fins absorb the heat from the plate.
The fins then radiate the heat away.

If there is a fan used along with a Heatsink, (Such as in the Power Supply, or on a Processor), the fan moves air in-between the fins, and around the fins, helping to carry the heat away.

If dirt, dust, hair, etc. is clogged on the fan blades, center hub, and surrounding cage, the cooling capacity drops tremendously.

The fan cannot move the needed amount of air.

To include on the Heatsink/s inside the Power Supply.

The gunk acts like an insulating blanket, causing the Heatsink to retain the heat, not conduct it away.

Heat = Wasted Energy

The Power Supply tries to keep up with the call for power, and eventually cannot, due to hardware components failing inside.

The Power Supply may seem like it is operating okay.

Lights light, fans spin, and it may sound as though the Harddrive inside is operating.

The Power Supply could have a weak Voltage power rail.

Power Supply's are rated in Wattage.
1) ALL the lights use less than 1 Watt of power.
2) EACH fan uses 2 to 3 Watts.
3) A typical Processor can use anywhere from 51 to 125 Watts.

A bad Power Supply with a weak Voltage power rail, will have enough power to light lights, and maybe spin fans, but not enough power to turn the Processor on.

Harddrive sounds like it is working, because the Platters inside are being spun by the Spindle motor.

http://computer.howstuffworks.com/hard-disk.htm

There is no Processor operating (The 'Brain') to find the boot sector on the Harddrive.
Platters are spinning but the Arms aren't moving the Read/Write heads across the Platters.

In short the computer is not operating.

No video signal to the monitor, because there is no computer operating to send a video signal.
Bad Power Supply.

Monitor (no signal) after replacing mother board and CPU


try only connect Monitor and keyboard, and check for booting (disconnect all the rest (HDD, CD DRIVE, Sound Card, Network Card, ....) then try connect one by one and always off to change hardware config.

If dont work with monitor and keyboard, try reset bios(jumper),check again, then replace memory modules (must be compatible to new motherboard), evan dont work, send back the motherboard for defective motherboard.

PC is not working. Monitor message says 'monitor


Check to make sure that you have it plug all the way in to the video card. Also make sure that the video card itself is seated or pushed in good.

You could possibly need a new video card or the pins on the plug coming from the monitor could be bent.

HP (dv2000) laptop will not boot up at all


It appears to be a video card/mainboard problem very common with the symptoms you have described. Try to connect the laptop to an external monitor (see the associated buttons too). No video signal on the external monitor could indicate a damaged video card/mainboard. Not worth it to be repaired and the replacement is expansive. Check the price on a professional repair store. There are new laptops on the market more powerful than yours for about 500-600$. So you can make a choice. Less common, could be a memory problem.Try the laptop with a good previously checked memory (or if there are 2 bars in your laptop, try them one by one). If you do not get any video signal on the external monitor have the laptop, first diagnostic is most probable.
In both cases, if you get a video signal on the external monitor it means your screen is defective (also expensive to be replaced).

No signal on monitor when card is seated


the problem occured probably because of a power shortage of motherboard battery malfunction, if your motherboard has an integrated graphics card you then need to enter setup and disable it or choose which graphis card your pc has to use but you have to do this while connected to the on-board vga slot as the other one won't be working, you will problably find the choice under the
'integrated periferals" menu in the setup menu, and to access it you have to press the "DEL" button when your pc starts-F10 in some devices-
