As I described in my other post post, it seems some problems in my PC were caused by DaemonTools... Things are as follows: - PC seemed real slow at times and didn't work as it should, more in the other post... - howard_hopkinso's advice was some registry keys deleting, which were reated to a daemon tools virtual drive, and proved to be the solution to my problems. Now for some things you don't already know: - Right after that, I installed a new Hard Drive, plus I connected my external HD after some time. - Result: same thing happened again (pc running slow etc), plus the virtual drive (the one that was created by daemontools and then removed when DT was uninstalled)...!?!? - Tried finding the same keys in the registry but I couldn't find them. Tried fiddling about with the registry but again, nothing happened... (of course the PC was restarted after every step) - Next thing was to re-install DT and then removing the newly created keys from the registry (the ones Howard had told me to), which succeded in removing the problem. After one more reset (for no particular reason, just to check it out) and guess what happened! Problem came back! - Then I tried un-installing DT and disconnected the external HD, and things went back to normal (problem gone). Notes: while fiddling about with registry settings, I removed one key about a program running on startup, that was named "NvDaemon" or something like that. Every time since that, something is trying to load that program every time the pc starts, but I have set ZoneAlarm edit: SS&D, not ZoneAlarm not to allow it from running. What is going on? Could it be caused by something inside my external hd or by daemontools?
