Windows XP SP3 About 4 months ago, my computer froze up, and I had to force it off with the power button. When I restarted, it would get to the Windows screen, but it would be stuck with the bar scrolling across. After 5-10 min I would get a blank screen, but no functionality. I tried reinstalling Windows but still had the same problem. After messing around for a bit I found the problem to be one of my hard drives. If it was connected, the computer would not boot. If it was disconnected everything worked normally. If I booted the computer without it connected, then tried to connect it, the computer would freeze while trying to initialize it. I formatted the hard drive, and everything worked great till last night. I opened a video file on the hard drive in question with Media Player Classic, the program froze and I tried to close it. The entire computer ended up frozen and I had to shut down using the power button again, and now I am in the same situation. With the same hard drive connected, the computer gets stuck at the Windows startup screen then goes to a black screen after 5-10 min. With the hard drive disconnected, everything works perfectly. I assume I can just format the hard drive again, but I would rather try to figure out what the problem is and fix it if possible. Any suggestions? Thanks in advance.
