Question A couple days ago, my PC started to randomly turn off in the middle of gaming or work. How can I fix this?

So far, I have tried reinstalling my driver software, checking to see if all my fans are working (they are), checking for software updates (Windows/Intel/NVIDIA), checking connections to and from the PC. I have a feeling is could a be a failing PSU, maybe?

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

Include PSU: make, model, wattage, age, condition (original to build, new, refurbished, used)? History of heavy gaming use? Or video editing?

Disk drive(s): make, model, capacity, how full?

Look in Reliability History and Event Viewer for any error codes, warnings, or even informational events just before or at the times of the "turn offs".

Overall if you see a history of increasing numbers of errors and varying errors then the PSU is a potential suspect.

More information needed.

Need the specs of your PC, if it's just randomly turning off then it could be to do with the PSU.

It can be overheating so check your heatsink if it is making good contact with the CPU.
or maybe your PSU is failing, If you have extra PSU or something you can borrow then test a few hours on gaming on it, if your problem still continues.
