Boot Loop When I Leave my Computer.

[Linus_is_a_Badass]

When I leave my computer on in a hurry, I come back in nine hours and often see it's in what I think is called a boot loop. The monitor has no signal, and I hear my CPU fan at top speed, then it goes down by about 1/4th the speed, then back up to full speed over about a second. I don't know why, but I feel as if it might have to do with an unstable overclock despite through RAM and CPU stress testing. What should I do?

If you suspect its due to the overclock, dial back the overclock and see if it helps the issue.

1. It might be unstable as my gpu sometimes crashes after extended gaming loads.

2. It might be overheating.

It's definitely not overheating, under a synthetic load intended to make as much heat as physically possible, it hits 80C. I think Ryzen's max is 95C. I had a stable but too hot overclock at 4GHZ on my Ryzen 3 1200(93C). So I keep it at 3.9. Should I revert to stock(3.1) for the test or something like 3.5? It was just a hunch, nothing more by the way.

3.6

This is going to take a while

I don't think this will be all too helpful, but what shows up in the system event viewer is "The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly." Event ID 41  on a critical level (duh). I found 3 instances of this.

just test stock clocks, if that doesnt help it might be psu i had quite similar issues and psu replace fixed it, im not saying im 100% right but it might be

I have tested my PSU with a multimeter two weeks ago, everything is within 5% even under load. I'm looking at my event viewer some more, and it's becoming apparent that my graphics card is responsible for most if not all of these.  I don't have anything too concrete, but I have seen symptoms of it, so it makes sense. This dumb r7 240 needs replacing regardless of if it's broken.
