Brother's graphics card malfunctioning?

[Raziaar]

Well... he was playing Jedi Outcast, and I was watching him. Suddenly the screen develops these stripes across it, black.

I tell him to close it out. They follow him into the windows desktop. I tell him to reboot... they're there in bios and the power on self test.

So I removed his CPU fan/heatsink, applied a new layer of thermal compound, fresh and good. I also removed the graphics card(radeon 9800 pro 128mb) and dusted it all off completely. They are still there. We tried putting our old geforce 3 in there, and it works fine. So it's definitely the radeon that is having issues.

Is this a overheating problem? When mine overheated(the fan stopped working), it didn't show artifacts in the POST. Only in games I think. But I can't be exactly sure. I do know that the fan on his is working.

I am thinking of getting him the same cooler type I have for mine. What do you all think?

The artifacts I'm describing are numbers and characters all over the screen in a sort of gridlike fashion.

Turn on V-Sync and Update Drivers?

The chip could have been damaged by overheating. 9800pro's are known to run hot (and not very long).

Mine ran for a considerable amount of time when the fan stopped working... while I was playing oblivion. That's when I realized the fan stopped working. It was hotter than the surface of the sun when I touched it.

My 9800 Pro took a lot of abuse and still worked. Sounds like its just overheating...

I bought my graphics card a few months before my brothers. Same type. A few months ago, mine started crapping out, so I had to put a new fan/heatsink on it. It seems reasonable to think that a few months have passed, and now his is starting to crap out... so I ordered the same one I have in mine, and hopefully we'll get many more years out of it.

The geforce 3 and geforce 4 we own still work beautifully. He's using the geforce 3 in his computer right now... and amazingly, it's allowing him to run dark crusade without any lag for the most part, at same graphic settings.
