Did you run an antivirus or antispyware scan recently on this computer? The
behavior you describe is usually what happens when an antivirus or
antispyware program identifies a file as malware, deletes the file, but doesn't
clean up the mechanism that launches the malware at startup.
Here's a program from Microsoft that will help you stop the error messages.
AutoRuns for Windows v9.13

Once you've downloaded and extracted the files, run autoruns.exe.
Look on the Everything tab for an entry that lists ijqwllxq.dll in the Image
path column.
Right click on that entry and select Search Online from the menu.
Odds are that you'll come up with an empty search. This pretty much confirms
that it was some type of malware that your scan deleted.
Uncheck the item.
Restart your computer. If you no longer see the error message, you can go back
and delete the entry in Autoruns.
Just to be on the safe side, you might consider taking steps to make sure the
system is malware free. Here's a site with general instructions on cleaning a
computer.

As for having to select an operating system, go to Control Panel and double
click the System icon. In System Properties, click on the Advanced tab. On the
Advanced page, hit the Settings button in the Startup and Recovery section. This
should launch the Startup and Recovery dialog where you click on the Edit
button. This should open your boot.ini file in Notepad. Copy the contents of
boot.ini and paste it into a response to this message if you want help fixing
the problem.
Good luck
