I went away for about a month and had my computer off but it was plugged in. when i came back the computer would not boot up. Sometimes it can get past some of the bios screens and i can get into setup but it will go black during setup also. It made it into windows once before it crashed. Sometimes a message will appear in bootup that says overclocking failed even though i have never tried to overclock and my bios is set to normal and not overclocking. Im guessing it is either my motherboard or chip that has gone bad but i am not sure. any suggestions?
