Heya all, well this is my first post so a big hi to all. Well i recently got a new comp, i picked the parts and the store put it together and so on. Now the first prob was the 7600 they gave me, it was faulty, so they replaced it wit a 8500 for free, kinda a downgrade imo. Eventually i got a 8600. But the problem is this, when they installed the 8500, i started getting random resets and crashes. Now im running vista hp so i though, ugh stupid vista but its entire power crashes and resets, no freezing while in vista. My guess is they have connected the PSU wrong, they may have good prices but they are definately not good at ne thing else =.=. Here are the specs below. ASUS P5B-E Mobo Intel(R) Core(TM)2 CPU 6420 @ 2.13GHz (2 CPUs), ~2.1GHz 4G DDR2 Ram (667) Nvidia 8600GT Usicase 500W silent power 2 140G HDDs in RAID0 I sent it back to the store 2 days ago, when i got it back the resets were more frequent. They are such a bunch of *****s it seems its down 2 me to fix the issue. Can anyone help me with this problem? i.e. Diagnose the problem? I have checked the connectors and no sign of fryed components, the sata HDD camble extention thingy has a loose pin, but it goes in fine. And yes while checking i was grounded and was on a anti-static mat. Im thinking there is a problem wit th PCU, so i aint re-plugging it until i know EXACTLY what i should blug into what power joint. Follow linear is the rule, but i dont wanna make a mistake. I am about to call the company again now and have a serious word 2 them, but they aint gonna be ne help. ne help is muchly appreciated. ty.
