BSOD after reformatting, 2 error signs

Are you still getting BSODs??

Yes, whenever I try and play TF2, it's only a couple of minutes until I get a BSOD.

I did not try the method that you linked with the Driver Sweeper, as I didn't understand it.

DriverSweeper is a relatively simple program to use. My principle concern is that in running it and selecting AMD Display->Analyze->Clean, with the issues you've been having installing your Video Driver, if the installation problem is because of a write permissions problem to a particular directory or registry key or something like that then, I'm a little afraid you may be left with no driver an no way to install a driver until you resolve the root cause of the overall Video Driver installation problem. So...... deciding whether to use it or not, I will leave up to you. As I've said it is relatively simple to use as long as you are careful as to what you select and pay attention to what appears and is checked in the analyze results window before you click the clean button.

I'm probably not going to attempt that, as it's better to have something than nothing. Hopefully there is someone else with more experience in AMD cards to help, but thanks anyways.
