When I boot up my desktop computer, it runs through the BIOS and then goes to a black screen with a blinking _ and wont let me input anything. This happened after years of working fine and no new installations, but the computer screen abruptly turned black while working on it and after a restart I got this boot problem. In the BIOS the MoBo recognizes the all the hardware, and when I try to boot from the windows cd it asks to hit a key to boot from the cd and when I do it just goes to the black screen with the blinking cursor... Is this a hardware problem with the MoBo? or a software problem?? Thanks for any help!
