If you have a desktop motherboard i would suggest to see if you CMOS battery is not dead.

I would go with checking the CMOS battery first, button battery type CR 2032. Then move on to the RAM or PSU possibly.

I would go with checking the CMOS battery first, button battery type CR 2032. Then move on to the RAM or PSU possibly.

Especially if it says "Defaults loaded", it's your battery almost without question. If it hangs and you have to reset it yourself, still check the battery, but it could be something else. Memory would be the thing. I'd suggest running Memtest86+ and letting it do a few full loops.

If Memtest comes up clear, I've seen it be an issue with the BIOS itself. A firmware update might solve the issue, but this is something you'll want to be rather careful about.

As with most computer problems, detail is key. Including what hardware you have, what BIOS settings you apply (if any), and exactly what happens and how to recreate the problem will go a long way in helping us diagnose the problem.
