Your driver is corrupt or out of date. update the driver. To do so, download it, then restart your computer in safe mode, uninstall the old driver and install the new 1.

any clue as to where to download it from?

First place to check.

ok dl'd the new driver from katsumi's link how do i uninstall the old driver(s)?

i'm pretty sure of how to install new one tho

Could be that you're letting your GPU run too hot. What is the temperature while running GW for a while? Old/bad graphic drivers don't normally cause you to BoD or reboot.
