Hello guys! I really need some help here. This is making me really nervous.

So, last week my PC shutdown by itself. It has happen before because of bad weather, but this time it did and it started to smell like burnt. I was playing a video game when it happened. I unplugged it and left it there for a few hours without using it. When I went back to plug it and turn if on, the smell was gone. I thought it was probably because it was overheating, but that wasn't the issue I guess. A few hours ago it did the same thing when I was playing another game and the burnt smell was there. So, I did the same thing like before. However, this time I took everything out and check if there was any burnt on any of the parts. Nothing! I took the PSU out and clean some dust and the same goes for the rest. I also took the processor put and put a new thermal paste.

This time I was really scared because I thought the SSD might get damaged as well. The problem with this issue is that nothing was smelling like burnt after a few minutes when it shutdown. I have no idea what might be the problem. When I connected everything back and turn the PC on, everything was normal and functioning. I have no idea what is the problem. So, could some of you please help me with this. I really don't want my PC to end up not working if this keeps happening.

A few notes for you (in case it might be helpful).
  • I haven't installed or replaced any new PC parts.
  • The same problem happened twice in a matter of a week.
  • Nothing seems to be burnt or smells like burnt.
  • Every hard drive, GPU, Rams, Processor are working just fine.

I would suggest taking some canned air and doing a THOROUGH cleaning of your computer, spraying out any dust especially in the heatsink and in the power supply. See if that is the case to start with...
I already did that. I took almost all of the dust off of the PCU and the rest of the parts. Hopefully that was the issue because I have no idea what might be after all.
