I had put my pc on sleep mode for the night and when I powered it up again yesterday I was greeted with 2 short beeps, 1 long beep and then 1 short beep to finish it off. I looked up beeps and some ppl say motherboard, others said graphics card error or memory is loose. Any info from this venue ?
Without knowing who makes your motherboard's BIOS (AMI, Award, etc...) we would only be guessing. Highly suggest asking on the forums of whoever makes your motherboard.
