This is my 5th system I'm trying to put together and I'm having a hell of a time. Here are my specs. LanParty UT nF3 250gb mb AMD64 3400+ clawhammer Seagate 160 gig 7200 SATA 1 Gig Corsair Value Select 400 mhz Tried ATI 9800 pro & gforce ti4200 Motherboard is set to default, no overclocking. The problem I'm having is I either lose video completely and system still stays on or the system completely shuts down for no reason. WTF! I've tried new PS, It's generic 680w 22a and it's still doing the same thing. Heard this board uses a lot of power. Please if anyone has any suggestion, I'll try anything. I'm about ready to throw the whole thing out the window!!! PLEASE HELP!
