I left my computer last night in perfect condition, working great and everything. Now this morning I went to my computer room and i just saw a black screen so i was like...well ok w/e....So then i rebooted and i saw my bios screen pop up for about 1/2 sec. then everything went black again...i checked all cable connections, which are good, and my video card is in my computer good. If i had to guess it seems as though its a motherboard problem...right? anyone have any ideas of what to do?
