PC turns off then when i turn on

[TestButton]

Didn't know where to put this question, but if someone can tell me where the right place would be that would be great!

This has happen twice Ill turn my computer on at night, it'll be running fine but nothing shows up on the screen, then it'll just turn off. Then i turn it on again and everything starts to work fine It has done this twice. Monday night and last night (last two times i was on my pc), but this morning it worked fine. I am good 99% it doesn't have a virus, because i only go on Netflix and steam and really no other website.

Thank you

How old is the Pc? If it is several years then it's likely some caps are starting to fail on the power supply or the mobo. (the thinking here is something like this: the charge-up time on the caps is so long that the first boot up fails, but once it has been powered on for some time the caps are charged properly and the second boot is succesfull)

Please provide a complete listing of the components (make/model) of your system. Initially, this sounds like a possible power issue (like a failing power supply).

With the complete specs for your system, we should be able to come up with some options for a solution to your problem.

Are you overclocking anything (CPU, GPU, memory)? Also, what are your idle and loaded operating temperatures for the CPU and GPU? If you don't know the temps, download and install hwmonitor (run in background) to determine. Get it here:

Nothing is overclocked. For temperatures i can not say since i am on a work computer and not my home pc right now. But i don't think heat would be an issue since i haven't had that problem before I have spent hours at a time playing video games.
