*Edit/update by bluem: DriverCleaner didn't delete more than intended. This was my mistake. Read below for details; it may help you avoid a similar problem with nvidia drivers (or similar).* Hi - I just purchased DriverCleaner today. I used it, and now I have suddenly lost my mouse (won't move the cursor) and my Internet connection is gone (who knows what else). No change even after multiple reboots. Monitor and LCD are also NOT working - running in some sort of minimal/safe mode without full graphics. So apparently DriverCleaner has cleaned out some necessary drivers that it wasn't supposed to (besides display drivers; I assume that's the main target). I don't have any other explanation. I am not a hardware guy, so bear with me. I *use* computers for website development but I don't build them nor do I understand the inner workings of hardware, drivers, etc, etc. I am using my old Windows 98 computer to type this since my win xp computer is now hosed. Computer specs as best I can: Windows XP, SP 2. AMD Athlon 64; ASUS motherboard, and I think, looking inside my box, that nVidia is embedded in the motherboard. DriverCleaner said I have ForceWare 81.85. Why I was using DriverCleaner: I recently installed an LCD (ViewSonic vp930b) but at random moments the display would crash and I'd have to restart. The exact error: "The wpfb_nv4_disp driver has stopped working normally..." and I'd have to reboot. So I was attempting to see if an nVidia driver update would solve the problem; hence using DriverCleaner. What I did: I downloaded the latest nVidia driver (ForceWare 93.71). I first used the nVidia cleaning filter; I then used Add/Remove programs to uninstall Nvidia drivers, restarted in SafeMode and used DriverCleaner nVidia filter again. My computer locked up after I attempted to uninstall PerfectSuite (color management software for my new LCD; I didn't want it to get in the way). Upon reboot, my mouse doesn't work, internet connection gone, etc. I tried installing the downloaded nVidia driver, but it did not change anything, not even the display, after reboot. So I uninstalled it via Add/Remove. No change again. When I intially installed DriverCleaner, I had clicked the option on DriverCleaner to backup all files and registry. I tried to restore files/reg using the backups, but I can't click the boxes without a mouse -- and tabbing to "Select All" and pressing Enter does nothing (it doesn't select all the files/checkboxes as I assume it should). I have one disk that might possibly have basic motherboard drivers on it but it doesn't respond in the CD drive. Not sure why. But I wouldn't know what I was doing even if something did come up. So, any ideas? I need to get my computer running ASAP. I do not want to have it in the shop for a week and/or have to do a complete system reinstall. Please advise.
