Correct me if "deadlock" is not the right term, but randomly my PC's screen would freeze as it is, no blue screen errorr and sometimes with buzzing from the speakers. The mouse and keyboard freeze too (Caps or Num light won't turn on or off) and I am forced to restart it by holding the button, then I can turn it on as normal. Usually it's while I'm in the middle of playing a game but sometimes just 3 mins after startup, and it's not overheating. I've tried almost everything; Disk check, troubleshooting, memory diagnostics, looking on BIOS (though not really sure what to look for), even a complete reset, which gave an error message "could not reset, no changes were made". Starting to think it's a hardware issue but not sure.
