registry cleaners are gimicks, simple as that. they are only for developers who keep on installing and uninstalling programs.
though cc cleaner is useful for many other jobs.
now it seems like hdd is to blamre. man whats happening?
How is cleaning your registry a gimick?? Any time I uninstall something it leaves traces in the registry. In fact the only way I could get my latest sound card drivers to install was to run CCleaner after uninstalling it. Took 3 tries to figure that out, and then it worked.
OT: Could be bad connections/cables and/or a bad motherboard.
