Hey guys i am having a bit of trouble with my pc, i was just playing some siege and it just shut off and will not turn back on. At first when i turned on the power button the lights would flash really quick as if it was turning on but it would just instantly shut back off but now i am not getting any lights to turn on. Does anyone have any ideas of what this could be?

Best thing to do is unplug your PC and plug it in after 15-20 minutes. Make sure the outlet you are using is good, try to use a new outlet. Also auto shutdown is ALWAYS PSU related or heat related. If the PSU has a bad cap or weak rail and can't keep up with the load or the CPU's thermal protection kicked in. And if it's heat its almost always the CPU.

while true a dead ram stick will make it fail during POST thermal throttling usually lets you boot back up for a couple seconds whereas op is describing it being unop

okay so i have tested the psu and the battery on the motherboard and they both work. I reset the ram and it is still doing the same thing. I checked the cpu and there is like no thermal paste but i read that i could use toothpaste to test it so i put some tooth paste on it and it's still not working. Any ideas?

Try to plug in something else into the socket you were using, let's say a lamp or try to charge your phone. Just to see if the outlet you are using is not messed up.

Defo sounds heat related to me. Not ruling anything else out but that's where I'd go. Easiest way to test if it's a heat issue is let the computer turn off, unplug the power and just feel around for hot spots. Obvs, if your CPU is hot then it's that because your cooler wouldn't be doing it's job.

You don't by any chance have a liquid cooler on your CPU?
