I have been using ccleaner for a couple of years with no problems on my windows XP SP3 PC. Today I ran it and it hung while cleaning the wastebasket. After about 10 minutes I killed off the process and then started getting errors with IE so I rebooted. The reboot seems to get stuck for about 5 mins before the display of the login page, but eventually seems to complete ok. When I try to login, the wallpaper is displayed but then nothing else... I can boot the PC in safe mode and everything seems to work ok, including ccleaner!
Dont know whether this is a ccleaner error or ccleaner was just the first to find the error.
The event log shows the errors as ccleaner"application hang" at the time I first had problems. "Sidebyside" errors occur about the time I login (but not in safe mode). The SidebySide error may be a red herring as they have accured many times of the last few months, but I have not had problems logging in before ...
System restore is my next step, however I came to the forum to find out if this has happened to anyone before. If I do a system restore without finding out what caused the problem, it could well happen again.
I booted the PC in safe mode and noted the name of the driver that appeared on the screen when the boot stopped. I googled the drive name with "login hung" and a large number of very similar problem problems appeared all on XP. The majority of these were fixed by starting the restore console and using the fixboot command. As I did not have an up to date restore console available, I restored the system to the day before the problem. Problem fixed. I am expecting the problem to occur again when the MS updates are re-applied, but at least this time I will have an up to date restore console to fix the problem.
