Well, It ran good for a few days but now my computer freezes after about an hour of use. Every when the CPU is Idle. It is an Athlon 2900 XP with a 450 watt power supply. When the power supply hisses slightly is when the problems start. They are video problems too. The screen gets discolored or broken white letters even at startup. The videocard worked in another machine preveously, but sometimes the monitor just goes to standby mode. The CPU is running a little hot at 65C with a big load. And when I put a load on it with a game the computer has gotten progressively worse over the last few days. It use to be able to run a game for a little bit, but now it freezes the computer almost immediately. And now I cant even reinstall windows without the monitor going to standby for some reason. Will changing the new cheap power supply to one that is Athlon ready, and not cheap do the trick? I have added a battery back up AC device that stablized the voltage from the house because the refrig use to drive my computer nuts.
