I need some help. I messed up my Registry about a week ago & could not boot. Let me preface this by saying that even though I have been using a computer for many years, I am a novice at trying to fix Windows problems.
I tried to do a system restore using cd \, cd system~1, cd resto~1. I got back that it could not find the file. I guess this means that it could not find a viable restore point. This may be because my System Restore has not been working for a long time.
Having failed to do a system restore, I tried to do a system repair, using a Windows XP CD - sp2 level. I performed a chkdsk /p & fixboot. I eventually did a system repair, using R & enter keys - I am a little fuzzy on exactly what I did. But it took a long time to read in all the files & I eventually got a screen to enter my Windows 25 digit code. When I finally booted in Windows mode I got an error screen:
OFVISEX caused an access violation in ntdll.dll at 0x7c9106c3. Click close to terminate the application. Click ignore to continue.
The computer appeared to work pretty well - a few IE freezes & Err - must shut down. I did a few things to get my computer back to the level I wanted. When I tried to update all my windows files to sp3+, using the MSFT web sites, IE vs 6 would not work - would not open. All white screens. Looked strange. Malwarebytes would not run.
I then did a system restore to the level it was when I first came out of the Windows repair procedure. The first time I booted up after this system restore, I got the Error Mssg I got above --access violation in ntdll.dll. At this time my IE worked, but not very well. I get a lot of IE freezes & shut downs. Other strange things. Can't uninstall my Malwarebytes. Can't uninstall my Realtek AC97 Audio. Got 35 copies of Windows Task Mgr on screen at one point.
I have Kapersky Internet security 2010.Ran it in regular & Safe Mode. It shows no virus/Malware. Also ran Trend Micro online scan. Ran Panda online active scan. Reinstalled Malwarebytes in different folder & it now works. Ran it in regular & Safe Mode. I don't think virus or malware is a problem.
Today I tried to run another Windows repair procedure, using the procedure you have posted on this site. When I got to the screen that shows your existing Windows XP installations, the C:\windows installation was not shown. I showed my M:\ Windows installation. This was the backup I copied when I first bought my computer. It is only to the sp1 level. My Win XP cd is to the sp 2 level.
Anyway, I don't know where to go or what to do next. Need lots of help.
Thanks in advance for any help.
