My first question is about canned air. Are you cleaning your PC's vents on the 1st of the month?
Several times a day the screen will freeze and the PC will have to be rebooted. Also, it will sometimes freeze, the screen will go black, but then come back after a few seconds lag.
No information is lost on reboot.
Any ideas for a fix are appreciated.
