My PC hasn't been used in a while due to it having a pirated version of windows xp and refusing to accept the service packs. I bought a new OS for it. I tried to go on it to back up my files but when the monitor is turned on, it will light up for about 3 seconds before turning off. I thought it was a fault with the monitor, so plugged the input into my laptop and it worked fine. I have opened the case to clean the motherboard and graphics card which was removed.Is there a way to reset the computer so it will register the moniter? The only socket is on the graphics card. Any help would be greatly apreciated.
Thanks (i dont mind completely reformating the computer)


127.0.0.1 is where your heart is
 
Sounds like a bad connection/dying graphics card to me. You said you removed the graphics card, this mean you tried the monitor on the onboard graphics, or did you try the graphics card again?
 
The only output is on the grapgics card, there isn't one on the motherboard. I replaced the graphics card firmly after identifying it.
 
The link didn't work, you need to select the picture, right click it, and select "view image" and then post that link.
It sounds as though the motherboard is faulty.

You are correct, the red card is the graphics card. Try taking out your graphics card, blow at (or vacuum) all the dust that maybe in the slot, and put the card back in. Make sure the card is completely in and see if that works or not.
 
ok do you have an internal speaker to hear if it is posting?? Or can you hear the harddrive loading?? If not then I would check your 4-pin power connector as it will cause similar problems.

You might want to try and switch memory slots and reset the cmos.

I would suspect the 4-pin connector from your power supply though.

If it was the 4-pin power connnector the computer wouldn't POST nor would it come on. If it was a faulty HDD, it would still display video.
 
yes it would not post but the cpu fan would still run as it gets power from the 20 pin

I had the same problem with a computer of mine and I lucky had another power supply and that is what fixed it.

If your computer is NOT posting I would remove the heatsink and place a finger on the cpu. Then turn the pc on and see if it starts to heat up if so shut off immedialty (unplug it) and reinstall heatsink. If it is not getting warm than your cpu is not getting power either from a bad voltage regulator circuit on your motherboard or your power supply is not giving it power via the 4-pin connector beside the heatsink.
If your computer IS posting but with no video than I would suspect a bad MB or GPU.

if you are getting a screen for a sec or two when powered on than I would swap out memory stick.
