I recently upgraded to Windows 10 from Windows 8.1 and after I did, my computer didn't boot up as fast and was laggy after logging in also coming up with "Display driver stopped responding and has recovered" and below that (in smaller text) it said "Display driver AMD driver stopped responding and has successfully recovered" it has blue screened twice, the first being the driver crashed when I left the computer idle and the second I don't know. This only started happening after I upgraded and was running fine on Windows 8.1. I am also thinking of downgrading back to Windows 8.1.
Also, just to add I have AMD Radeon R7 200 graphics, an Intel Core i5-4690K CPU @ 3.50GHz 3.50GHz and 8GB of RAM.
I don't know what to do, please help, Joel
