A while ago I bought some S-ATA disks and installed OS on it.

I got it working and all but windows kinda lagged and crashed almost all the time. So I tried to repair windows and then it said:

Windows could not start because the following file is missing or corrupt:
<Windows root>\system 32\hal.dll.
Please re-install a copy of the above file

I reformated but it still says the same thing. I have tried quick format and just format. Can anyone help me?? I really want to use my comp. It's my main rig to so I'm on a teahatty 500 Mhz laptop now.
