Over the past two days, my computer has crashed whenever I play games. Two days ago, after a few hours of playing, my monitors basically shut off, however I was still able to hear sound. The next day, my PC crashed again, this time with no sound playing after the crash. The computer still makes sounds, so it is not fully off, as well as my keyboard is still lit up. The crash occurs after a few hours of playing, and once I restart and go into a game again, it happens almost instantly. This made me think it was a overheating issue, however my PC has been cleaned of dust, and various programs have shown no real heating issues.
Something to note is that in the BIOS, the cha_fan 1 / 2 / 3 were in red, going between 490 RPM to 580 RPM. We increased the upper temperature of these fans to 50c to have them running faster at lower temperatures, but after doing this and trying a game, it instantly crashed. I am not sure if this is linked in any way.
One other thing is that the Radeon R9 280x was installed about a month ago, due to the previous 7970 dying. It has worked perfectly fine, so I am not sure if that is a problem.
Things I have tried:
- Cleaning the PC
- Checking all plugs are in correctly
- Running a memtest (ran through 2 times)
- Increasing 6h4 fan speed
I was thinking that it may be due to the power supply, but I am not too sure how to check that.
