Input devices will not respond! New hard drive problem? Hey everyone, I joined this forum to see if you could solve my problem. I got a new hard drive a while ago and i installed it when my old hard drive was still installed. I didn't know much about jumper settings then so i just left both my my hard drives with the master setting. I reformatted my computer soon after with XP home on the new hard drive. However, XP pro was still on my old hard drive but my computer worked fine until 3 days ago. The green motherboard light was on and when i pressed the power button the fan would spin. The computer would not turn on though. I then waited for a few hours and tried again, to my suprise it turned on perfectly. Now, 3 days later, the motherboard light is still on, but the fan will not even spin when I press the power button! What do you think is preventing my computer from turning on? Thanks alot.
