Monitor goes to sleep when I play mw2!!!!

[misterWARFARE]

Okkk. the problem is, when I play mw2, my monitor goes to sleep mode and wont wake up after 5-10 minutes of playing. the weird thing is I only experienced this issue with mw2, And I know its not a heat issue cus I can play crysis and GTA IV for hours whithout having any issues. In other forums they wer asked to change the settings for when your monitor goes to sleep mode. I changed mine to never and the problem is still appearing :/ I tried reinstalling the game but it didnt work either.

plzzzzzzz help!!!!!!!! This is really pissing me off!
