I have had this for some time, i have updated my GFX card drivers and it doesn't help.
My PC Spec is:
Intel P4 3.2Ghz Prescott
1GB DDR RAM
Geforce 6600GT 256MB 256-bit
20GB Western Digital IDE HDD (i thought it might be this, its from my old pc)
Please anyone with any solution please help, i don't want to have to format my computer.
