ATI Radeon HD 4870 Code Name RV770
Error persists with over-clocking disabled.

Windows 7 Service Pack 1 (64-bit)
My issue is that when playing a specific game (Dota 2) my computer shuts down with an error message involving atikmpag.sys. I believe my driver installation is corrupted, because this started happening when I upgraded the driver (not sure what the original version was.) If I try to install a new driver version, I receive a BSOD in the middle of the installation with a message involving Plug and Play and a Faulty Driver. If I try to uninstall the driver, I receive a BSOD with the error involving atikmpag.sys. If I repair the driver it doesn't fix anything.
In Dota 2 I play with Anti-Aliasing x2 and no VSync. When it crashes, I get a bunch of squares on the screen that are about 10 pixels by 10 pixels.

Display Device(s) and Connection(s) Used
Just a single monitor with no special connections.
Applications and Games
Crashes when playing Dota 2, and when trying to uninstall or install a different driver.
Intel Core 2 Duo E8400 (3.00 GHz Dual Cores)
Motherboard BIOS Version
Dell Inc. A19, 5/31/2011

Considering all of the crashes have errors involving a faulty driver, I am pretty sure it is not a hardware issue. If it is a hardware issue, it might involve overheating, as I've seen my GPU reach 105C, but it looks like that is normal with the HD4800 series.
