I've been having some trouble with a computer I built a few weeks ago. It seemed to be working fine for the first few days; however it started to reboot itself randomly. There doesn't seem to be any pattern to the reboots, I can go a few days without seeing one or they could a happen several time in a few hours and it doesn't seem to matter what I'm doing at the time.
Most of the time, the computer just shuts down instantly, like someone cut the power and then it starts up again by itself. There's no blue screen or any kind of error message (Ive disabled automatic restart on error) and it's listed in the event viewer as a "Kernel-Power" error. Sometimes the computer will completely freeze for around 30 seconds before shutting off and starting up again. I have had 2 blue screens, however these both occurred very close together and I havent experienced any since. The errors listed were:
INTERRUPT_EXCEPTION_NOT_HANDLED and IRQL_NOT_LESS_OR_EQUAL
Ive also noticed occasionally when I shut down the computer and try and start it up again right away, no image will be displayed on the monitor. Everything else seems to be working. But Ill get no image.
Ive tried testing all the obvious things; however Im running out of ideas. Unfortunately I dont have access to another computer to test the PSU or the motherboard which is making this quite difficult since Im beginning to think one of these might be causing the problems.
Heres a list of what Ive tried so far. None of these have allowed me to identify the cause or prevent the reboots:
The only ideas I have left are the PSU and the motherboard. Which of these seems more likely, or is there something else I can test?
Here are my system specs:
OS: Windows 7 Ultimate
CPU: Intel i5-4570 3.2GHz
Motherboard: ASRock H87-PERFORMANCE
GPU: Gigabyte GTX 770 2GB
RAM: GSkill Ripjaws-X 8G Kit(4Gx2) DDR3 1600
PSU: Antec Neo Eco 620C-BR 80Plus Bronze 620W
Thanks for the help.

Heres a list of what Ive tried so far. None of these have allowed me to identify the cause or prevent the reboots:
- Monitored temperatures: They never go above 75°c even when I stress the system using prime95, furmark or the intel burn in test and theyre usually around 30°c - 40°c while idiling.
- Ran memtest86 overnight: Tried with both sticks, each stick individually and in different slots and never got an error.
- Ran with 1 stick of RAM: Kept getting reboots with either stick.
- Updated all drivers: No effect, bios was already up to date.
- Ran without the video card: No effect
- Switched all the SATA ports and SATA power connectors
- Unplugged the DVD drive
- Checked all plugs were secure and no capacitors appeared to have died on the motherboard
