How do you mean low voltage. Oh as stated by polarbear: With a more balanced power PSU. If the card is demanding more power than the rail on the PSU can carry it will fail or show signs. It's an educated guess as to the PSU being an issue. It would be great if you can get your hands on a known working unit large enough to handle you system and test it. Use this link as a minimum guide.

Wish you were close by as I have a working 600w we could try !
Mine is actually 700w and that calculator gave me well under 400. I don't think PSU capability is the issue. It should and has worked before and rather reliably.
Such a strange issue. I'm going to take it to the clean room again. Maybe they can magically fix it simply by trying another psu and putting the old one back in again. Frustrating.
Thanks for everyone's help, by the way. Any other ideas would be greatly appreciated.
Sounds like a plan, wish I had a clean room to take my computer into and have magically fixed. lol
All symptoms have me pointing the finger at the PSU.
Yeah, I think you're right. Any suggestions for a replacement? Cheap but capable.
Don't care. Not looking to spend a lot of money though. So far, this one looks ok:
Newegg.com - CORSAIR CMPSU-650TX 650W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Compatible with Core i7 Power Supply
I'm not comfortable with how it's actually less wattage than my current PSU. Also, my current PSU is under warranty but it will literally take a month to get the replacement.
It's a little smaller than what you have and you say you are using no more than 400watts so it we do the job and if it does the job I would send the other in under warranty. Always better to go bigger or the same but for test purposes only it will do the job. GL :)
Corsair PSU's also gets a lot of props here. Check out this Thermaltake as well: Thermaltake TRX-650M TR2 RX 650-Watt Modular Power Supply - 650W, 140mm Fan, ATX, Modular, 80 Plus at TigerDirect
Went with the corsair. Free shipping and $10 off coupon made it worthwhile. A total of $60 for that thing is a bargain.
I only hope the PSU is the only problem. You all know the feeling. It better be the only thing.
Thanks for your help guys, I'll report back when I find out for sure.
I had what seems to be a similar problem to you after I installed my new cpu cooler, would light up and the cut off within a second or 2. I thought something had blown up or caught some static, but in the end I pulled everything out of the case, even the motherboard and put it back in and it started right up.
