Hello I have a ATI Radeon HD 4870 GPU, and I believe something is corrupted. Whenever I try to install a new driver, my computer gets a BSOD (PNP_DETECTED_FATAL_ERROR). The BSOD contains a message about a faulty driver. It always occurs when the install file reads "Detecting Graphics Hardware." The associated file with these BSOD's is ntoskrnl.exe.
I also receive random crashes often when playing games. Those errors always involve a problem with atikmpag.sys. Also my screen constantly flickers up and down. When it crashes in game, I get a bunch of 10x10px squares on my screen before the BSOD. I have noticed similar crashes due to overclocking the GPU, but even with overclocking turned off, the crashes still happen.
I have spent hours trying to fix this, and eventually I uninstalled the drivers using DriverFusion, since it would crash when using AMD's official uninstall. The computer is now stuck without a driver since I still can't install the new one.
The post here has the same exact issue as me, and I've seen several others like this, but none of them have a definite answer that fixes it. http://www.sevenforums.com/drivers/128815-bsod-when-un-installing-ati-graphics-driver.html
EDIT: The system specs on my profile are for my laptop, and this problem is on my desktop.
EDIT2: I included the Diagnostic Tool info. I currently have an Intel Video card in the computer, but it is much less powerful than the Radeon and I really need to fix the faulty AMD driver.
