I bet you guys thought I'd never be using this forum huh?

Well this isn't really for me so much as it's for my friend. He has been having some very odd troubles with his video card and believes that either something is misconfigured or is fried.

His laptop which is a Toshiba TE2100 has on it an nVidia GeForce 4 MX GO with 16 MB on-board, for some strange reason has been having trouble while doing 3D things [size=9px](playing a 3D game using DirectX and OpenGL and such)[/size]. However when he is not doing anything with his 3D [size=9px](ie. in Windows)[/size], he's fine.

Now, the problem steammed from a while back where he remembers running a program called ENTECH POWERSTRIP 3.x[size=9px](you can get it at guru3d.com)[/size] that he used to overclock his GPU. The card's original speed was 200MHz which he increased by about 30MHz until he saw some 'artifacts' as he calls them [size=9px](tiny little blocks of pixelized crap on his video screen)[/size] then set it right back down to 215MHz. He also set something on the program where it "Forced a 32bit Z-buffer mode". He had his GPU overcloked for about a week.

I originally concluded that he fried his chip, but he wants to eliminate any possiblities that it might be something else before deciding on that. The problems that occur [size=9px](3D texture effects that are drawn on screen go all funky colors like the texture memory is being currupted somehow, and sometimes the game will crash sating that the device has failed)[/size] only happen after a few (5-20) minutes. Which leads me to believe that it's not completely burnned out at least, but he believes that it might be some setting thats messing it up.

What do you guys think it might be, if it is not a fried GPU and is it possible to have parts of this thing burnned out and still be able to run 3D programs for a small amount of time like this?
