I've got a gigabyte ex38-ds4 and never have had any problems. 2x2 gigs 8500 ram at 1066 2.2v. factory specs, e8500 clocked at 3.35 at 1.28v., 700 watt thermaltake tpower and a thermaltake 250 watt booster with two six pin connectors pinned into one 8 pin. and a bfg gtx 280. The problem is my machine boots slow for a second or two fans and all running, Then stalls for 5 or 6 seconds then boots like nothing has happened!! This happens like clockwork every time i boot up! What does anyone think , bad capacitor, voltage regulator or does it just like having time outs? I don't know, there should be plenty enough juice. Not running raid, just sound card, hard drive and writer. Does anyone else have this problem? Or should I just rma everything. No just joking!!! PLEASE TRY TO HELP OUT HERE. I'm going nuts about this!!
