ok so my secondary cruncher is having problems big time. the rig will get into windows chill there for a while then either shut down for lock up. now i figured it was a dying psu so i bought a new 530w psu and the psu runs my main rig (in specs) no problem but the secondary pc still does it! tried 2 diff cpus celeon (45nm) and p4 (90nm) tried swapping out ram same its getting annoying. im starting to think something is wrong with the mainboard mainly because it has no video problems no artifacts etc and while it runs I can get a game runnning fine until it inevitably shuts down. tried fresh install and halfway through the install the damn thing shuts down anyone have any insight??
