Just hard reset your pc and it should come back, using the power button or if you have it reset button.
Sorry i meant the wrong thing look at the latest post and see if you can help. Thank you
Ive looked it up and alot of people seem to be having the same problem:
just make sure of these things and try it:
update graphics drivers (also what gpu do you have?)
Save your mw3 saves and reinstall MW3.
Most people who had this problem, it was a problem with their gpu drivers, I would check that out.
