Hi I just upgraded my old system 3800+ dualcore @ 2400MHZ DFI LANPARTY NF4 UT Expert 1.5gb ram When I play games eg: Need For Speed Most Wanted, GTA San ANdreas or Never Winter knights The game tends to speed up sometimes. I will be playing GTA and I am walking the streets then all of a sudden It's like I am running 2x speed of running.. then it goes back to normal speeds... The clock in GTA goes faster too. same things happen with the games I wrote above. Please help..
