Question PC powered off suddently - now only stays up for 20 seconds and powers off again.....

Suddenly just powered itself off....
Tried to power back on, came back on, splash screen, then same again. Powered off. Tried 3-4 times.....

I'm thinking overheating PSU? I guess I'll see if it cools down.....

We're going to need more information in order to not assume what's the problem and try and narrow down possible culprits.

Please include your system's specs like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Case:
OS:

Also, state the age of the PSU as well as it's make and model and not just it's wattage.

Think its an overheat issue. Old PC which, to be honest, is a little dusty and needs cleaning.
Its been fine for years, no issues, so hardware config is not going to be the issue here.

PSU is a decent Corsair one too.

Anyway, booted ok once it had cooled down. Cleaned it much better now.
