Windows keeps rebooting - help please!

///Rage · 6 Dec 2017 at 11:16

Hi,

My PC when cold booted often requires a number of restarts before it will load windows. It is particularly bad the first time I turn it on after a day or so away. What happens normally is I get the Asus splash screen followed by windows trying to load. My USB devices light up (keyboard and joystick) and then it'll turn off and try again. It can do this a few times before windows finally loads. Alternately it will attempt to 'diagnose the problem' as windows loads up or even try to repair the disk drive (no problems found).

Specs: [email protected], Asus z77, 16gb ram, 980ti.

Once loaded up its completely stable in gaming and prime95 with temps 40-65C under load.

Any ideas if its the PSU/Mobo issue?

I'd try swapping out the PSU, preferably for something a bit beefier just to check that's not the issue.

Id be wondering about the capacitors though this board looks fairly solid.

Indeed, something definitely seems unhappy when cold. Motherboard would be second possible culprit after PSU but is annoyingly trickier to diagnose or fix.

Almost certainly either capacitors or the RAM doesn't like cold booting both a bit of a pain.

Occasionally a peripheral can throw it out (sometimes an indicator of a PSU fault) but usually that just recovers after the second boot and not take multiple boots.
