Temperature too high? Or not enough power?

Symptom:
1. When I play WarCraft 3/Morrowind/Battlefield1942, sometimes the screen freezes and metallic sound continues to repeat itself.
- When I check the temperature, it is around 52~57 degrees C.

2. When the system is idle, CPU temp is around 49~51 degrees C. When the system runs the program it is around 55~59 degrees C.




Here is my system spec

I want to know what is wrong with my system.
It is keep crashing on CPU intensive 3D games!!!
It is annoying!
(I have suffered 5 straight losses in Battle.net Ladder... FRUSTRATING!)

I think its too hot and underpowered ;)

Going by those temps it seems your CPU cooler is fine but case cooling isnt what it should be. Although it is within specs and should run fine. With two 80mm exhaust fan you should be getting 40C at idle and under 50C full load with that CPU cooler.

The PSU seems too small to power an athlon let alone all those IDE devices and an 8500. See if yours is in this table.http://www.sigem-elektronik.de/compu...n/athlon_p.htm

That would give me nightmares. Ive seen small PSU's burn out and take almost every other component out with them.
