Slight problem

[Ventus_754]

Hello all, my system has been stable since i built it 3 months ago and all of the sudden i have been freezing during very low end games such at warcraft 3:TFT, any way i though this may be a videocard problem and so i reinstalled the drivers and still i have this problme. i reloaded my mother board drivers and still i am geting it also. The board is a MSI ms-6570 and the card is a Geforce4 Ti 4200. please help if you can thanks
