Now the system works well as a normal workstation, but my problems occur when playing, which sucks as it was meant as a gaming system. First I installed XP 64 bit but went back to the regular XP after a lot of BSOD and other bugs.
But back on XP 32 bit the problems still occur, with the game stalling and crashing, sometimes I get a BSOD and a restart other times it just crashes back to desktop.
I've downloaded and installed all the latest drivers (tried both the ones from the hardware manufacturers site and from the components site), flashed to the latest stable BIOS version.
And it has improved, now it's possible to play the games for a longer time before it crashes, all from 30 min to 3 h. A game like BF2 crashes within seconds of play whereas lost planet and counter-strike is on for 30min - 1 h before it crashes.
It underwent a hardware test, as I thought I got some faulty part or something, but they couldn't find anything wrong with the parts.
So I'm starting to wonder if there is a compatibility error in the parts. I am strongly suspecting that the memory I bought doesn't work with the motherboard, also another suspicion of mine is that it's the built-in audio card that's haunting.
Memory: Talked to a guy at uni, he told me that he had a hell with finding good working memory with his PK5 motherboard.
Audio: Sometimes when playing the sounds get all nasty, then the program that came with drivers pops up, and it shows that the speakers have been unplugged then plugged in again, But no BSOD those times.
So I'd appreciate it a lot if you guys could come with suggestions on what the problem is.
ImajorI: The temperatures are acceptable: with the CPU never going over 40 Celsius and the graphic card peeking at 70 Celsius (read that people have reached well over 80 without any crashes) so it seems that it isn't a heat problem.
Have a lot of fans cooling the system, one in front of the Graphic card as well. The system temperature when idle is 26 Celsius and goes up to around 30-32 Celsius when playing.
The problem with a more powerful PSU is that I would have to get a new one as that is the strongest one I have at home. Might as friends, they might have one I could borrow for a couple of hours.
