I put together a new build and was able to use it without any problems for the first day. Installed windows, updated, restarted numerous times, etc.
On the second day, the computer would not boot. Hitting the power button made the CPU and video card fans spin momentarily, but nothing further. I took unhooked everything from the motherboard and reconnected them one by one and it seemed to do the trick.
The computer worked fine for the next few days, then I turned it off earlier today and now it's doing the same thing. I tried unplugging and replugging everything back in to no avail. I worked through the suggestions on the post of things to do when computer does not boot. I have checked the standoffs as instructed. I also tried breadboarding the MB, CPU, and 1 stick of ram, same results. I have tried resetting the CMOS. Same results.
