A friend of mine gave me his old 8800gt and I've had problems with it. I know that the temps on those cards are high so I have no real problem with that, However I get random lock ups with strange triangle like squiggly lines all over the screen. I have a 500 watt power supply so I don't think that is a problem.
Any help would be really appreciated, I don't want to go back to my 9500gt.....

Could be no telling how long my friend had it. my idle temps are usually around the late 50's up to 80 on full load. But as I said before 8800's are known for heat.
