dell inspiron e1505. XP SP3. had some malware which I removed. Then I got cute and downloaded some registry cleaner. Malware gone. Reboot. Mousepad and keyb don't work. Try to add usb mouse but cant click on ok to proceed with loading drivers. Have a BARTPE bootup disk but dont know which registry keys to edit. Boot into dell diagnostics and keyb and pad work fine. Please help. I've seen numerous references to upper filters but all threads seem to die without a response.
