Hi I'm knew to the forum and am in desperate need of help. My system made a crazy sound and then shut off, I smelt something burnt and now my system won't boot. I had my 3.0P4 OC'd to 3.78 running at about 38 Celcius, so I don't think I burnt my chip, I think it was the crappy Orion 420W PSU. Here is my setup: NZXT Nemesis Elite w/ Orion 420 W PSU Asus P4P 800-E Deluxe MB ATI AIW x800xt SB Audigy Platinum 1 GB Corsair Value Select Ram What do you guys think? When I try to power the sys on, the MB light does not even go on , which to me means either the MB fried or the PSU did, and I hope someone will help me confirm this. Is there any way to test the PSU? Thank you in advance for your help.
