I had many BSODs that I tried to fix with a 3rd party application to update drivers. The application installed the wrong version of the graphics driver, causing more BSODs. The first BSOD fixed itself with an update. I uninstalled that driver and installed the latest version. Unfortunately, more problems were to come. The driver did not crash, but lagged severely on games, singularly, Minecraft. Normally, this game runs extremely well even with many background applications and multitasking. After the driver update, even the main menu had an FPS of no more than 3. In-game, the FPS reported by Minecraft was stable in the bracket of 1-3, making the game entirely unplayable. The path taken to reach this point makes driver rollback impossible.
Steps taken to troubleshoot:
1. Restart computer
2. Clear Java cache
3. Update Java to latest (7 u15 64-bit)
4. Made fresh install of Minecraft
5. Install Optifine (Minecraft Optimization mod) to make sure it wasn't a game error
6. Did a quick defrag
Needless to say, they didn't work.
The one thing I haven't done is install a new graphics driver, because I'm not sure which one to install. That's where I need your help.
