blue screen on start-up

by brendons31 / June 13, 2009 8:17 AM PDT

Hello, I have a problem with my Dell computer where on the start up it comes up with a blue screen saying:

stop: c000007b bad image. The application or dll \??\c:\windows\system32\sfcfiles.dll is not a valid windows image. Pleace check this against your installation diskette

This probem started when I wanted to do a disk defragment. It came up saying that first I needed to do a chkdsk thing. So I tried to do that and it said I had to restart the computer to make it run. So I did that, it did the chkdsk thing and then went to the blue screen with the error.

Each time I turn my computer off and back on, windows starts loading up, then it gives the option of doing a chkdsk, or pressing any key to continue. So I either do the chkdsk, and that runs for a few minutes and goes to that blue screen, or I press any key and that goes to the blue screen.

Also, I have tried going into safe mode on start up to try to fix the problem and to back up important files. A big list comes up on a black screen with a whole lot of lines with the last line being....


So I need some help in resolving the problem, or even in being able to back up important files if this can be done without safe mode. Thanks.

Let me know if more info is needed.

I run Windows XP Media centre edition.

Since sfcfiles.dll is something we could fix let's find an article to GUIDE us on how to do that. You did not reveal if you had your Dell XP Media Center OS CD handy so if you lost that then it's game over and you proceed to saving files. finds OTHER discussions but let's move on to the repair.

Read "Step 5" at and we see we can copy in a fresh version of that dll. Just substitute sfcfiles where needed.

Fairly painless to fix.

-> File recovery. Today I use a hardware approach to file recovery in instances like this. I use a cable like this -> and can reach over and grab the files from other machines. PAINLESS! CHEAP TOO.

Hey mate, cheers for the response. I lost my windows xp disk along time ago.However,my girlfriend has hers, but hers is windows xp home edition, and my system was windows xp media edition, does that matter?

I have done a bit of google research on this myself and tried to perfrom some functions on my computer using her windows xp disk. Unfortunately, my computer has taken a bit of wear and tear over the years,and there is one key on the keyboard which doesnt work, which hasnt really worried me in the past, but would be very useful. The : button is not working on my keyboard.

Yes but since you have NO ALTERNATIVE you can proceed to step 5 and hope.

Keyboards here run from 5 to 500 bucks. Why would we keep a busted one?
