I had some adware and pop ups earlier today so I thought to myself, "lets scan to see if there are any problems." So I scan with AVG. After the scan my computer rebooted itself and I am introduced to a world of XP problems!

-The login screen is not normal. You know with the multiple users and fancy pictures xp stylie? Now it looks like a windows 98 login screen where you have to type in the user name and password. With a creepy black background.

-Greeted by several errors that say these files cannot be found:
MSVCR71.dll
NyCpl.dll
Oleacc.dll

-Sound is not working
-Normal start up items are not appearing

***AVG and AVG vault will not open because of the msvcr71.dll error.
***Have tried system restore, but after computer reboots it says it cannot restore (have tried several different dates)
***Downloaded and installed Eusing Free Registry Cleaner, found a bunch of things, but not fixed any of my original problems
***I just moved to a new area and I have no clue where my windows XP cd is, so using that is not an option

Alright. Any ideas? All help is greatly appreciated. Thanks in advance.

There's very little, if anything, you can do without the XP CD. Guess you're just going to have to find it.

"***Downloaded and installed Eusing Free Registry Cleaner, found a bunch of things, but not fixed any of my original problems."

This was not a good idea. Regoistry cleaners can do more harm than good. See the pertinent "Announcement" at the head of the Threads listing. Also see comments below I copied from another well recognized help site.

Advice and Info re Registry 'cleaners'- excerpts from TSG:

The main reason they are apt to cause problems is because the cleaners do NOT just clean up stuff left over from uninstalls. They also "guess" that other items need to be deleted, many times incorrectly. They also attempt to "fix" references to files that no longer exist.

As a result, you can end up with programs that no longer work, functions that no longer work and in some cases a PC that will no longer boot.

There is no performance gains to be had by running these things. Windows does not read the entire registry when it is looking for something. It uses the keys which allow them to go straight to the item that they are looking for.

If you really want to see how active the registry is in your normal running environment, download and run Regmon.

As you will see, the registry is constantly being accessed. If, for each of these, the entire file was being searched, your PC would be amazingly slow and not responsive.

And, to repeat this again, they make no difference in the machine's performance because they are based on a false premiss about how the registry is accessed. Unused entries do not slow it down.

If you have or once you find a XP disc, boot up the computer, put the XP disc in your CD tray, and from a command prompt type SFC /SCANNOW this will reload all your missing / overwritten files. This should also work from the recovery console.

 

[speedster123]

did you do a system restore

try and borrow an xp disk to run the system file checker

ok anyone else? no one here was really any help

Refer to my first reply in this thread. :wink:

 

[mrneonsky]

Alright I found the cd! so now what?

 

[mrneonsky]

i did the command thing but apparently the windows version of xp i have isnt the same one anymore as the one on my computer so it won't fix the problems

 

[kev1952]

If SFC didn't work then it's unlikely a repair install would work either. As you now have the CD why not do a complete clean install? Would solve all your problems in one go. :normal:

I have EXACTLY the same problem as you and posted my own thread on the 11th Dec.

Sadly I do not have an XP disk. Please let me know if you have any advice or manage to get rid of the problem.

System restore or complete Re-installation...
But you need a XP CD...
Less painfull and quicker than cleaning already very infected and damaged system...
Borrow CD from a friend...
