What did your friend do to your computer to speed it up? I'm wondering if your friend ran a virus scan and took out a corrupted .dll file?

That particular file (rundll32) is located in your Windows/system32 folder of your operating system.

What I would do is to go to another computer and copy (DO NOT USE THE CUT COMMAND ON THIS TASK) that exact file to a thumbdrive then go to your computer and follow this path:

Single right click onto the Start Button

Select Explore

Under My Computer/Local Disk (C:) look for the WINDOWS (all upper case) folder and open that up.

Open up the folder that says "system 32" and look for the file labeled "rundll32"

If you can't find it in this folder simply install the copy from your thumbdrive into this folder and reboot.

If you can find it, that particular rundll32 file is probably corrupted so you'll have to remove it manually and insert the copy from your thumbdrive.

Reboot and that should fix that error message.
