Hello, my computer is crashing in a very strange way and im really not sure what causes it. My computer will crash about 5-10 minutes after startup and then restart, after it restarts it is fine to use for an indefinite period. I have tried reinstall windows and cleaning the heat sink. All of the fans are operating properly and the computer often does not feel hot after the crash, I have run a virus scan and my computer seems clean. What can I do? Any help is appreciated.
