system freezes have to wait 10 to reboot after a hard shutdown

[dangos79]

System locks up, needs time before it can be restarted

I have a newly built computer that locks up usually 10 to 15 min after booting usually I am browsing the internet then pages won't load then my browser freezes and I can't Ctrl apt Del. Then everything freezes and I have to hard reset but the computer won't boot up unless I let it rest for 10min

Everything in the computer is brand new
I have it running the bare minimum
1 stick of memory
The hard drive

I noticed in the bios that the 5v and 12v are low
The 5v is running around. 4.2
The 12v is around 10 .4

I've spent 2 days trying different things, any help would be greatly appreciated

I have tested the CPU and even re installed it
I have tested the memory it seems fine
I have checked the wires
I have reset the bios

It sounds like it could be a faulty power supply OR some of the capacitors on the motherboard are going bad. Try a new powersupply first see if that fixes the issue.

Does your computer make beep sounds when it fails to boot?

Also please provide us with your full system specs including cpu cooler and power supply model.

Since I can't find any details regarding this power supply this could potentially be a power delivery issue if this power supply is some kind of cheap Chinese brand.

Not 100% sure so if I were you I would check system / gpu / cpu temps using HWMonitor and if everything is fine, try to swap the power supply with one from a well known brand with 80+ certification (Corsair CX line of power supplies is a solid, inexpensive choice).

If temps are fine and you don't have access to a better power supply / don't want to waste money on another power supply without knowing 100% that it'll solve the issue, I believe your best bet would be to have your computer checked by an expert.

Just my train of thought, if anyone comes up with a better suggestion please bring it.
