I have tried updating some of the drivers, I am not really good at figuring out on how to do them all. Besides that, at first it was critical corruption error, later system thread exception not handled, and one-time watchdog which hasn't come back. System thread exception has come and gone, while critical corruption has stayed since about 3 weeks ago. I have run out of things I could think of trying or at least understand how to try, which is why here we are. The other thing is this is not on my pc specifically but my boyfriends. Memory test was good.
Thank you for your help and time.
