I have had this issue a number of times over the last few months and not found the cause of it.
I will be playing a game on my rig and it will randomly reset, try to boot and a second later stop. After pressing the power button to try to get it to boot, it does nothing.
It will then do nothing until I completely power it off and then it will do the same thing again.
Here is a video :
To solve this issue in the past I have taken parts out of the pc and tried to see if it will boot and it does. I then put the whole back together and it works for a day, week or more until this happens again. I am trying to find the cause so I can stop it happening again.
Specs:
i7 4770k gigabyte oc force motherboard 2 x hyper ssd's in raid 2 x Gigabyte GTX 780 ti AX 1220 i psu 16gb of basic ram 3tb hdd western digital blue
This is going to sound crazy since I have a oc force motherboard and a custom water loop but it is all at factory speeds
I did think this as well but since it first happened I have had it happen again within 20 minutes of fixing it (and I wasn't gaming them), the 3rd time it happened was after a week of long sessions playing doom or dark souls 3.
The rate at which it happens does not seem predictable enough to be thermal. Surely playing the same games it would roughly heat up the same way?
Does your UEFI reset it's settings after you do that whole dance to get it booting? tbh it's abit wierd if your not OCing, then id atleast understand it could use some time to cool down abit. usually BIOes/UEFI's have a 3 strike and we reset policy, sometimes it works, and sometimes not. but it may have something todo with that. Where for some reason your UEFI is fecked and has to reset. Maybe try a update.
I was just getting ready to post this... From my experience its a failing PSU. If you have another to try out you should. Also get a Bronze or higher PSU don't skimp on the PSU
check gigabytes webpage and see if there a bios update. UEFI's are usually blessed with a function where you can run the .bin file directly from the UEFI itself. DISCLAIMER!!!!!!!!!!! be sure you got the correct file for your mobo, flashing your mobo's bios with a incorrect .bin file can get ugly(e.g. brick your mobo, so no 3rd parties!) but it should be fairly simple just check your mobo name and find the drivers for it section, usually the files and what not are named quite correctly for it. fx. my manufacturer names as such. A88XM-PLUS-ASUS-2903.CAP not much to be mistaken about there Just don't take any chances if you're uncertain
I know there are updates for it but I cannot remember if I downloaded them when I last installed windows but the system was running fine for 9 or 10 months without issue before this all started
It is cool. I went overboard with the psu for the same reason. Good psu will help with over clocking if I were ever to do it and if I were to add more gpu's.
I do not have another psu to test it. The only other psu I have is 240 and my rig draws more than that.
