Question Computer turns on for 1 minute then turns itself off

[chuncie]

Hi there,

My computer has been running fine for a couple of years now, but this morning i started my pc and after 30 minutes it shutdown.

Now every time i go to turn my pc back on it stays on for about a minute before it turns itself off again.

I started my pc and let it idle in BIOS and i noticed that my CPU temp would gradually rise until 80 degrees and then shut down. I remounted my AIO cpu cooler, reapplied thermal paste and made sure that the fans etc were correctly installed but the same thing still happens.

Here's a video of the CPU temp raising until shutting off in BIOS

Could something be wrong with my Motherboard that's stopping the cooler from working? or should the pc just not turn off even if my CPU gets that hot?

Quite confused about what's going wrong in my system, any help would be much appreciated!!

Update your post to include full system hardware specs and OS information.

PSU: make, model, wattage, age, condition?

Look in Reliability History and Event Viewer for error codes, warnings, and even informational events that correspond with the turn-off's.

Power down, unplug, open the case.

Clean out dust and debris.

Verify by sight and feel that all cards, connectors, RAM, and jumpers are fully and firmly seated.
