Since the time I bought the PC around two years back, the screen goes blank for a few seconds every so often (in intervals from a few seconds to a minute or so). This happens continuously until I restart the PC, and then it may or may not happen again. There are times when I switch on the PC and the screen does not go blank at all until it is restarted. This makes me suspect that the issue is not with hardware.

Following suggestions from community posts, I have reloaded BIOS and drivers, but the problem persists. I'd appreciate help in identifying and fixing the issue. Thanks in advance!
