Computer has to boot twice to start correctly

My computer is of the homebuilt variety. Specs:

Intel i5-760 @ 3.15GHz
Asus P7P55 LX
Gigabyte GTX 460 1Gb
4GB Patriot Sector 5 DDR3-1333
Windows 7 64bit
et al

When I start my computer, it will not boot all the way into Windows. Sometimes it will get into a reboot loop after POST and sometimes Windows will give a BSOD. Reboot does nothing. If I turn off the computer using the power switch, then turn it back on, it boots perfectly. I've gotten to the point where I turn it on, immediately turn it off ASAP, then turn it on again. Works like a charm.

I've flashed the BIOS, reinstalled Windows, reseated the memory, and rechecked all my connections. Any other ideas?

Thanks for the link, but everything there checks out.

I have an OCZ ModXStream 700W.

PSU is fine size wise. Everything points to either motherboard or PSU though causing this issue. What codes do you get on the BSODĀ“s.

I just tried to replicate the BSODs, but this time, it got to where the microsoft progress bar for windows would come up and just reboot. It did this repeatedly until I turned the computer off and back on, then it booted normally.

Did you find a solution to this problem? I have the same exact problem. I'll boot it up and it shuts down. The 2nd time it boots up with no problem.

Possibly a glitch in the standby power circuits inside the PSU. Try to borrow a PSU from a friend. Or pull yours and use another system to test it.
