Hello, i just bought myself a gigabyte gtx 460 1gb. When i install the drivers provided my pc goes to BSOD right before login, the driver version is 258.58. A rollback would be useless now because the gtx 460 wont work on any older versions of nvidia drivers. would i have to reformat and reinstall my OS (win 7 ultimate 32-bit). I'm sure this is not a hardware problem. thanks.
