So, I built a PC about 3 years ago and it worked fine until about 5 months ago. It started randomly shutting down for no reason. After a while, it would shut down after being on for about 45sec or less. At first I thought it was a virus or something, but according to all of the virus and spy/ad/malware scans it’s clean. I uninstalled each component down to just the mobo and the PSU and tried to power up after each was removed and I still had the same problem. Since I couldn’t figure it out, I just got a new mobo and installed it. It worked up until about a month ago and then started shutting down not even a minute after trying to boot up.
I then gave the PC a thorough cleaning thinking that would solve the problem but it didn’t. I have since replaced the RAM and that didn’t fix it. I thought the PSU was the problem so I got a new one and installed it today. That didn’t fix it. I just uninstalled everything one at a time trying to power it up after each component was removed again and it’s still doing the same thing.
Does anyone have any idea of what is going on?
