Receiving the mssage during boot

I receive the following message wihil Booting a Dell Deminsion desktop:

Services.exe - Bad Image
The application or DLL c:\windows\application\AcGenral.dll is not a valid Windows image.  Please check this against your installation diskette.


Then when I click OK, the boot continues and I get another different Message header:

lsass.exe  Bad Image
The application or DLL c:\windows\application\AcGenral.dll is not a valid Windows image.  Please check this against your installation diskette.

Continuing on, I get other messages with different Titles but the same body telling me to check AcGenral.dll against the installation diskette.  In other words I get the same messate for whatever I do:
Logon on ..exe
explorer.exe

Finally the desktop shows but the messages still display like:
Realplayer.exe - Bad Image  with the same body:
The application or DLL c:\windows\application\AcGenral.dll is not a valid Windows image.  Please check this against your installation diskette.

So, what is this Acgenral.dll that I have to check and how do I correct it?

Thanks

Bob

First I would reboot into safe mode and run a virus scan to make sure your system is clean.

Then if the system is under warenty contact Dell and they can assist with the problem, if out of warenty and you have the OS (Windows) CD boot from the CD and run a repair install.

I should have pointed out the system does not come with the Installation CD.  Dell stopped shipping this cd with their new systems.  Rather, I believe you hit CTRL and then tap F11 when the system starts to boot.  (I was reading that somewhere on the forum).  So, not sure how to do the system file checker when I do not have the CD.

Also, if the CTRL F11 is the correct sequence of keys to do a install/repair, when exactly do you hit them when you start to boot, when you see the Dell splash screen or when?

I think when you see the dell splash screen, check the doucments that came with the PC for more info

System file checker does not need the CD to run (may need the CD to repair)

click start -> run
type sfc /scannow and hit enter

Hi Bob,

I hear what your saying, system file checker cant correct the system files without the cd, however you dont have a cd you have an image on another partition.

This is one way to correct this problem however i would run a good quality antivirus and Spybot search and destroy after this repair,

ok first swap into the installation partition, then you will be prompted like the cd if you want to install third party drivers skip this section,
next you will come to the three options one to reinstall, 2 to repair, 3 to reboot

in your circumstance it will be best to choose option 1, trust me we are not going to wipe out your pc, choose 1 the next screen appears asking what partition to install to select the one with windows already in it, the next screen will then ask do you want to install windows on this partition or repair OK THIS IS IMPORTANT BOB " i dont want to know if you select install a new copy of windows" SELECT REPAIR.

this will rewrite all your system files leaving the program files and file structure intact

cheers Bob hope this helps

elithaxor,   you say to swap into the installation partition.  How do you do that?  Is this the CTRL + tapping F11 I have been hearing about?

I am very familiar how to start a New Install (with a CD) and when it finds an existing OS, it asks you if you really want to Repair (R) or actually go ahead with the fresh New Install.
