running the radeon 3650 on a quad hp with 1tb of memory. Just installed a new hd and the damn graphics card updated on its own and wont roll back. I can't find the older driver but it used to work fine when playing left for dead 2 but now it's giving an error message saying texturecompression is turned off. What a crock of crapola! Anyone know what to do? I'm on vista 64 system. Thanks!
