I added a new hard drive to my computer. My original was to full, it had less than 9% free. After installing the hard drive, I changed the drive letters (I was told that it would be O.K., it wasn't.). After changing the drive letters, neither of the C D drives will work. The computer recognizes them, but when you put a disc in, it does nothing. I had to dig, but I found a message that said there is a block(?). I have un-installed the drivers and unplugged the CD drives and then plugged them back in. The computer re-installed the drivers automatically, but there is still no change.
The second problem is that two of my sign-ons are not recognized. I feel like if I could get the disc drives to work, then I could correct this problem with the Windows XP disc.
Can anyone please help me with this???
