I was running Microsoft teams and updating my raven coin core this morning when all of the sudden my monitor loses signal and I get black screens. I turned it on and off but to no avail of getting a signal. Then I did the only thing I knew how to do and was to take it outside to dust it off with an air compressor machine. It works, but when I left my computer on for 1-2 hours and come back, it loses signal. This has happened twice. Could I have a failing power supply or need a new CPU?
Thanks
