Graphic Problems

[nisrock]

Hi all i am experiencing a really odd problem and need help pinpointing the problem. About a month ago my monitor lost signal from my graphic card. I am not a computer hardware pro so i took it to the shop and the tech said he just reseated everything and it worked fine. When I brought computer home I still got no signal so i hooked up an adapter for 9 pin serial to the PIN on both end and fired it up. This worked, but if the computer is left off for a couple hours after i boot up i flashy screen from POST all the way to windows screen as if it is warming up. I have also had the monitor just go black in middle of a game.

After googling the problem i have come up with, it could be my card, it could be my power supply, it could be my cables and so on. what i have tried is connecting a second monitor to this computer and it worked fine with no flashing. the difference is my current monitor is a widescreen and the other was not. I have tried different DVI cables with no luck, infact if i use DVI cables i get a no signal on screen.

I believe it is the graphic card about to conk out on me. Does anyone has an idea of what is going on here, is it the card or something else?

A couple of questions

How old is the graphics card?

Have you updated drivers?

Ok now if you have done the above ^ then try this:

1. Try a new cable to your monitor
2. Try using your computer on another monitor
3. Remove all your RAM besides one stick and see if it could be faulty ram (happened to a friend)
4. If at all possible, try another power supply (i doubt its the power supply IMO but who knows. I've just never seen this issue with a bad PSU)

If you still get the same results, then it is more than likely your GPU.

Thanks for reply Uber. I have already tried the tried a second monitor and the problem was corrected. However the monitor was a 17" and my current monitor was a 22". This is probably why the tech guy did not pick it up as he was testing it on a small screen monitor. I also tried a Second set of DVI cable and got no results. Removal of RAM will have to wait a bit until the computer sits in off position for a bit. I am unsure if the tech guy re-seated the RAM.

I was thinking it could be the monitor which is about 2 years old now. The graphic card is about 2.5/3 years old. My drivers on the card are up to date. I will reply again after i remove the RAM

Just making sure im understanding this

You have tried the computer on another monitor and the problem went away?

Seems to me that the monitor is bad or at least the DVI port is bad. Does your monitor have a VGA port you could try?
