Geforce 2 PRO problems

[alien76]

After I have bought a new computer:
P4 1.6A, MSI 845Ultra-C, 256MB PC2100 RAM
My Geforce 2 PRO from LEADTEK have graphic problems in games.
After 10-45 minutes of playing any game ( SoF2, UT, Q3, 3Dmark2001Se and so on) small white triangels, squares and other geometric shapes appears on screen.
I try using different detonator drivers, different windows ( 98, XP) but this only solves a problem for a day or two ( not sure, because those days i didn t play much, and in Windows programs that problem doesnt appear).
Could overheating caused this problem ( graphic card isn t o/ced, I downclocked it from 200/400 to 100/200 MHz and it doesn t solve the problem) ?
Some months ago I heard weird voice from my case, which were possibly made by fan of 3D accelerator and it could be somehow destroyed!
Does anyone have problems like me?
Does anyone now how to solve this problem?
Graphic card is only few months old and is still in warranty so i will possibly have to use this way for solving my problem?

Thanks for replies!!

Your vga isn´t oc´d - ok !

@ what fsb is your system running?? Did you oc the CPU with a higher fsb??

Maybe your AGP slot is running out of spec´s!!

My CPU is not o/c
AGP port is at 66 Mhz

strange geometric shapes usually point to errors in the GPU core. A heavily overclocked GPU will show squares and triangles, etc, right before it crashes.

Are you saying your video card fan died? If so, this could easily be the cause of the problem. Open the case and double check that the vid card fan is still correctly attached and working.
