So yesterday i got home booted up my PC and nothing monitors were blank and not turning on and the pc would spin up the drives and fans then reboot constantly until i hit the power button.

I ended up opening it up and noticed it was a little dusty so i cleaned it all up.

It booted up fine, i played some games for a few hours and then all of sudden the screens went black and the pc started the same reboot issue.

So i pulled out the GPU and still nothing, stuck in boot cycle.

I pulled everything except cpu, ram and monitor. It booted to BIOS.

So i plugged in the SSD, booted.
Plugged in HDD, booted
Plugged in front USB, booted
Put the GPU back in, booted.

Not sure what the issue is.

I am not sure what the temperatures were when it crashed. I'm also not sure if either the machine cooled down enough to start or if a component is having issues.

I ran a memory test, everything was ok.
I ran S.M.A.R.T test on my SSD, everything is ok. (speedfan)
The temperatures using HW monitor or core temp seem fine at idle. So do the supply power to the components.

Any guidance would be appreciated.

Yeah, I mean, resetting the BIOS won't really do anything to harm anything. And definitely get the speaker in there too. And voltages can be fine, PSUs are finicky.

Try it and let me know!

Try pulling the CMOS battery on the motherboard, this will reset the BIOS. Leave it out for 30 seconds or so and pop it back in, and then try again.

If it's still happening, it might be a power supply issue. Do you get any POST codes at all when this happens?

EDIT: Be sure to take out the power cord before pulling the CMOS battery out.

So i got home from work and just wanted to see and it booted up fine. I did a stress test on my GPU and it seems fine. Should i still consider resetting the BIOS, worth a shot?

I didn't have a speaker on my motherboard to listens for beeps i picked one up today so if it does it again i can listen for the beeps. How can i confirm PSU issues? HW Monitor is showing voltages fine.
