    Hi There,

    I've been having this issue lately where occasionally, when I turn on my PC, it will start running, but just before it would normally beep for POST, it turns off for about 5 seconds, then automatically restarts and it will POST after it has restarted.

    This happens maybe 1 in... 20 times? And when my computer is running, everything seems fine. No random crashes during many hours of uptime. So I don't really have much of a problematic issue, however something isn't quite right.

    Not too long ago I installed a new 1TB SSD to put games on. When I first installed it, I had to boot a few times before Windows 10 would recognize all of my drives. At first it didn't recognize an old one, and then it didn't recognize the new one... But all the drives have shown up every boot since then.

    I think my PSU is nearly at its power limit for the hardware I have (see signature), and it is almost 10 years old (along with a lot of the other hardware), so I'm wondering if it could be a PSU issue? But if so, why is the issue so infrequent and I have no issues after POST?

    Any insight would be much appreciated :)

    You're not near the 650W limit of your PSU, even accounting for the age of the PSU, though personally I would be replacing it. My guess would be it being board related. Have you done a BIOS update?
