Okay so i recently started to get a postcode out of the sudden, i even reinstalled my windows and changed back to xp from 7. Sometimes i get a 2 short pause 8 short pause 1 short pause 2 short beep code, like 2 - 8 - 1 -2 and it will just boot without displaying anything on the monitor, i can hear the windows startup sound. What is happening?
