Whats going on now?
When I press the power button, the debug code on my motherboard nearly immediately goes to FF (boot), the fans spin up, and then the power drops out (usually within a second or two of turning it on). No beep code.
Current System:
EVGA 750i FTW motherboard, 2x Crucial Ballistix 2GB 1066 MHz RAM, Intel Quad Core 2.67 GHz, ASUS 480 GTX, Rosewill 950W power supply. 3 hard drives, and a DVD burner are also installed.
Problem History:
I previously had a Gigabyte 3D Mercury case (huge monstrosity with integrated liquid cooling) and the pump has been dieing for a year now. Last week I tried turning it on and it would near immediately power off. Figuring it finally died, I got a new case (This case has a built in circuit preventing it from being run without the liquid cooling.) and a new video card (I modified my EVGA 8800 GTX for liquid cooling.).
I got all the components in, installed everything in the new case. It booted but the video didn't display. With a lot of fiddling (very finicky seating), I got it to display and updated my drivers. Reset the computer and it was running fine for the rest of the night. I left it on when I went to bed at midnight, and it was still on when I checked at 3 am. I woke up at 7 am and it was no longer on. I tried the power and that's where I'm at now.
What Have I Done?
I have replaced the video card and have demonstrated that it worked (My old card worked as well, but I couldn't keep it running without coolant.) prior to last night. I haven't tried reseating any components since this latest issue (focusing on the power supply now). I have tried multiple outlets, with and without surge protectors (The electricians are rewiring my building - just wanted to make sure it wasn't something stupid.).
I have pulled out the power supply and checked each pin on the cables. My 12 volt line is reading ~12.43 volts; my 5 volt line is reading ~5.10 volts; and my 3.3 volt line is reading ~3.6 volts. The 12 and 5 volt lines are within the tolerance of the ATX spec, but the 3.6 volt falls outside the +/- 5%. I'm not sure if that is still acceptable or not or whether it would cause this problem. The power supply is a Rosewill 950W (not a great brand) and is over 3 years old. I do not have an PSU I can drop into the system to test.
----
If I need to buy a new power supply, so be it. If that will fix the problem, I'll do it and get it over with. But before I get one, I would like some assurance that this is indeed causing the problem. I have already spent much more than I would like on this and don't want to drop more cash on something that won't fix it.
Any help is appreciated. I've been working on this for about a week now and it's driving me insane.
