My pc seems to working perfectly fine for the most part but i have a couple of questions....so from a cold boot my pc gives the error code of "A0" which seems to be fine as i have read about.... now when i put my computer in sleep mode and wake it up the motherboard show an error code of "6f" and boots fine, i am just wondering why it changes and if that the 6f is a bad error code i should be worried about or not....
