Ive had this computer for a few months and over the past 2 months, it has sometimes, intermittently, said: Overclocking Failed and then not continue with the staretup. this is in POST, btw. i have never gone near the speed setting of my processor or anything. recently it came up with a 1 long, 3 short beep code error and nothing shown up on the monitor at all. the monitor does not come out of standby mode.
