I came home from work last night and the lights for my floppy and hard disks were steadily lit. My monitor was also on, but the screen was black and the cursor just blinks forever. When I restarted my computer, the only things it will do is check for memory (as usual), but then it does it all over again. the lights stay on and cursor is just blinking on a black screen. any suggestions? is if possible that it's the HD? But i just installed it last fall.
