I've just built a new PC which ran wonderfully for about 10 hours until I fired up Battlefield Bad Company 2 with max settings to see what sort of framerates (etc) I could get. My system was performing great for about 3 minutes when it suddenly shut off as though someone had pulled the plug. Now, when I attempt to turn on my system, nothing happens. No LEDs, no fans, no error codes, no POST. Maybe an occasional fan twitch.
While I'm not an engineer, this is far from my first build either, so I did some troubleshooting on my own. First I connected my old 500W PSU since this seemed like a power issue. There was no change so I reconnected my OCZ 500W. Then I started to remove components starting with the GIGABYTE GTX 460. The first boot attempt after removing the GPU was successful. The system POSTs successfully and I get a short "happy beep", although I do get an error code (d6) which on my board means that it can't find a video card. Go figure. So I thought perhaps I had a lemon GTX 460. I connected my old EVGA GTX 260 and plugged it in to the PSU, and the system failed to power on. It should be noted that it'll power on with either card sitting in the PCI-e slot without PSU connections, but of course will not output video.
So what I have here is a mostly brand new PC that ran great up until trying to game and now seems to have exploded in some way. It should be noted, that I had 3 rather old SATA drives and a DVD-R drive all connected at the time of the crash.
The OCZ 500W may have been a bad choice. My i5 2500k Sandy Bridge should peak at ~150W when coupled with my GIGABYTE 460 GTX which peaks at ~300W. This is already in the neighborhood of 450W and adding the HDDs and DVD drive maybe that's another 30W or so, taking me pretty close to the limitations of the PSU. Also, the OCZ PSU comes with only 1 dedicated 6 pin PCI-e power connector so 2 molex 3 pin connectors must be used for the second 6 pin connection.
I hope this is a PSU insufficiency problem, I have bought a reputable 750 W PSU that should be coming Tuesday. I have tried many of the steps listed in your troubleshooting guide
Someone please tell me this is a power supply issue!

I did try the other PCI-e slot without success.
