Hi guys,
I have a Dell 19" LCD set at 1440 by 900,at 75Hz,32-Bit.
My Graphics card is a Palit HD Radeon 4890 updated with the latest Driver version 10.8.
After exiting from Mafia II,which I play at all settings set to highest,my screen turns very dark,though not completely black & I have to restart my pc to get it to normal.
Is it a known issue??
Any help appreciated.

Thanks
