Geforce 7800GT XFX weird problem speed effect!

[Toxsickcity]

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..

Try running CPU killer to slow your system down a bit when playing older games.

I found the issue.....

It's to do with dual core...

Have to change the affarany cpu selection of the problem to only 1 cpu of the 2.
