Laptop display is flashing.........

All of a sudden my display screen is "flashing" when I move the cursor over most things on the display? It flashes as I move the cursor - it does not flash at all if I leave the mouse alone. Any chance it could be something simple like low battery in my wireless mouse? It is a Dell Inspiron that is only 6 months old. I've already had to have them come and replace the motherboard and display. They are telling me that it is a software problem, and I need to talk with their "paid" tech department, but I don't think so. I would really like a new machine. Would that be unheard of?
Anyone had this problem and found a solution? Thanks.

have you recently installed a new display driver by any chance, or made changes to the display properties (resolution)?

 

Nope

 

Safe Mode won't allow me to open IE. I restarted to regular mode and I am getting an error message that says "dciman32.dll is missing. Reinstall and try again."
Reinstall what?
I have a backup on an external. Should I just reinstall Windows? Or should I try reinstalling IE?
"Flashing" might not be the best term. "Blinking" erratically might be a better term.

 

Run the sfc /scannow System File Checker command to replace a missing or corrupt copy of the dciman32.dll file. If this DLL file is provided my Microsoft, the System File Checker tool should restore it
