Hi all, I've got a very strange problem that I can't reliably solve or reproduce.
Occasionally when using my computer, it'll just shut itself off and I can't get it to turn back on for a period of time. I can hear the HDD spinning and the mobo LED is on inside the case, but all my other fans aren't running.
Holding the power switch down will turn the HDD off and seemingly turn off the computer completely. Pushing the button again will power it into some weird state where the HDD is on, the mobo LED is on but nothing else happens with the computer.
I can't get it out of this state reliably either. I tried resetting the CMOS and sometimes it works and sometimes it does nothing. I have removed and reseated all the components at this point so nothing is loose. I've been monitoring the temps and nothing is high. The windows logs only show a kernel power error (essentially that the computer lost power suddenly) but doesn't give any indications as to why.
What seemed to work is taking the RAM out and putting it back in (currently only 1 stick in to see what happens), which I just discovered while typing this up.
It almost seems like the computer is in some sort of weird hibernation state and only comes out of that when the RAM is removed, but clearing the CMOS should fix it also and it doesn't do it reliably either. Sometimes it does and sometimes it doesn't.
Can faulty RAM cause a sudden shutdown and prevent a boot? I would expect an error screen or something in that case but I'm getting nothing. Or maybe a failing SSD?
I have ruled out the PSU being faulty on the grounds that if a loss of voltage or power across one of the rails was the culprit, it shouldn't prevent rebooting the computer. I pulled it out and tested the voltage on all the rails and nothing is low, but I didn't test it under load.
Taking the graphics card out and trying to start it didn't make a difference either in the 5-6 instances of shutdowns over the last 3 days, so although mine is old, I think it's behaving.
system specs:
Windows 10
i5 6600k, coolermaster hyper 212 cooler
gigabyte ga-z170xp sli
2x4 gb g-skill ddr4 -2400
corsair hx750
msi nvidia gtx 580
If anyone has any ideas, I'm all ears!
