Dell computer running XP freezes on start up and this error comes up: Bad Image, MoM.exe. The application or DLL C:\windows|System 32\ rqRIaBRJ.dll is not a valid image. Please check against your installation diskette.

We do not have any diskettes. The computer did not come with any from Dell. Help!!!!!!!!!!!!!!!!!

This, the DLL C:\windows|System 32\ rqRIaBRJ.dll is not a valid image... is the worrying bit. MoM.exe is a monitor, is all. Some legitimate files do have scrambled filenames, but that one looks suspect. Try this:
==Please download Malwarebytes' Anti-Malware
=Dclick that file, mbam-setup.exe, to install the application,
-ensure that it is set to update and start, else start it via the icon, and UPDATE it.
Select "Perform QUICK Scan", then click Scan; the application will guide you through the remaining steps.
ENSURE that EVERYTHING found has a CHECKMARK against it, then click Remove Selected.
If malware has been found [and removed] MBAM will automatically produce a log for you when it completes... do not click the Save Logfile button.
Examine the log: if some files are listed as Delete on Reboot then restart your machine before continuing.
Copy and post that log [it is also saved under Logs tab in MBAM].
==download hijackthis:
-copy it to a new FOLDER placed either alongside your program files or on your desktop.
-in that folder start HijackThis by dclicking the .exe
-CLOSE ALL OTHER APPLICATIONS and any open windows including the explorer window containing HijackThis.
-click the Scan and Save a Logfile button. Post the log here.
You can get both downloads in the first place, then run them.
