My desktop has been failing on me. It restarts out of nothing at times. After it reboots, there is no sign of improper shutdown.
I have tried booting my system in safe mode before running a full system virus scan, but it is a waste of time.
Opening the CPU casing is easy but there is not much dust inside for me to clear.
Now that I can only park my system in the BIOS setup screen to test if the problem lies with the operating system or the hardware.
