Every time I boot my computer from the power-off state, it works fine (cold boot). However, whenever I reboot the machine (ex: shutdown /r) it will hang on the next boot-up. This problem has been around since I built the machine and it is the same on Windows 7 and Windows 10 and various flavors of Linux. It will wake up from sleep ok, but won't successfully warm-reboot.

Probably unrelated: the screens of this machine never go to low power mode.

I've tried messing with bios settings many times to try to keep everything as conservative as possible. It has never been overclocked.

What could be causing this machine to fail on warm-reboot? What might I do to further trouble-shoot it?

Hardware:

Xeon E3-1225 v2 (3.2GHz)
MSI Z77A-G41
Radeon R7 200 Series
20 GB DDR3

Finally found the answer!

After replacing the video card, I noticed that reboots started working again. I went back to the old card and, sure enough, it was unable to properly reboot under windows.

I'm guessing this was a hardware issue with that particular card.
