okay, right now it isnt locked up, sometimes it just locks up randomly... anyone have any clue why? my system is at 22C right now, the cpu at 22C as well... pure idle it gets down to 19... under heavy load for 20 mins it gets up to 34C..... anyone know why this cmputer randomly locks up? Doesnt matter if its in a game or just in windows... anywhere from 2-30 mins after I start it up.. pooof! screen locks up... cant move mouse, or hit keys or anything.... installed 4.28 4 in 1 Drivers for VIA and up to date Radeon drivers... suggestions PALEEASSEE?!?!?

Most likely it's an issue with your radeon. Go into bios and disable 4Xagp. Change the driving control to manual and set it to 68. Disable fast write. When you boot into windows, start up msconfig by going through start>run>msconfig>startup and uncheck Atipta and Atipolab.

I have done all of that, disabled 4x, set to 68, etc etc.... I have the via 4 in 1 drivers 4.28 etc etc....

most of these problems started up a little while after removing the stock heat sink and putting on a better one of my own.. the problem is the thermal pad to stick them together didnt work, so im using artic silver and a rubber band.....not too flush.... also, in quake III, my frames per second are like a third of what they used to be...

What is your ram timing at. 133Mhz CAS 222? I had A stick of PC133 Micronics CAS2 in my KT7 and I would get the same thing. Left little green lines at the top of the screen when it locked. I switched over to Kingmax PC150 and have not had a lockup since. You could try turning down your ram timing and see if it still locks up. If it does, then that's it. If not, keep trying all the other suggestions.

T-Birds are really very picky about how the heatsinks are mounted. If you don't have it on tight enough and flat your temp will fly high. If you have high temps, than that is it.
