Hello everybody, I'm having the following issue with my PC.
I was using Revo uninstaller to uninstall O&O Defrag 10 from my PC as I had recently installed O&O Defrag 11. Upon rebooting my PC I received the following messages:
The archive for Iobit 360 appears to be corrupt.
Problem with corrupt file in Windows use check disc.
One of the files containing the system's registry data had to be recovered by use of a log or alternate copy. The recovery was successful.
My system was unstable, I rebooted several times and noticed that my internet connection was lost.
I tried safe mode with networking but was unable to get online. The system continued to be unstable. After some thought I figured I might as well attempt to recover my OS from the hard drive. First I unsuccessfully tried to use System Restore in regular mode, but was unable to use it. I tried in safe mode, and after a few attempts was able to restore my system to the day before, however, my PC remained unstable.
Upon attempting a reinstall I received this message: NTLDR is missing. Problems extracting NET Framework.
During the attempt to recover my OS from the hard drive system recovery partition I kept getting this message: Problems extracting files. I then tried to recover the OS from a set of full recovery discs I had made. I still kept getting the message: Problems extracting files. The first recovery CD was ejected and my system shut down.
Upon restarting the system it looked as if everything was working right, then I got this message:
Isass.exe System error. An invalid parameter was passed to a service or function.
I'm unable to progress past this point.
The system will start, and I will get a blue screen for chkdsk (I think) then I will get the above message Isass.exe and my screen freezes.
I'm at the limits of my sparse knowledge, and am requesting any help or advice that will get me back up and running.
I want to thank everybody in advance for your time on my behalf.
I await your advice.
