I have a computer which if very slow and I have tried to run disk cleanup, under properties for the drive in my computer. The program appears to be running, the hard drive light is constantly either on or blinking but the barometer either starts with 4 blocks and stays there or there are no blocks. I've tried several times and have left it running for up to 14 hours. It never completes although the hard drive ceases to flicker.
I have tried:
Norton utilities disk program and Windows programs from diskettes
Reloading Windows and overwriting the past installation
Defraged the HD
I still have the same problem
