I have an "envy m6" HP laptop which has switchable graphics between the onboard Intel GPU and what is, from memory, a 6600m amd graphics card (I think).
Due to the nature f the problem, I cannot currently obtain more information about the laptop. It does have a 3rd generation quad core i7 cpu and 8 GB of RAM. It has a Windows 8.1 64-bit OS.
I installed Catalyst Control Centre (CCC) 13.11, but evidently this was the wrong thing to do (even though i had installed and uninstalled other versions of catalyst previously) as can be seen in this post.
I tried to unistall CCC 13.11 (though it was only listed as "Catalyst manager" or something similar in programs and features) only to be told that it was corrupted and that the process was interupted. Instead I used the CCC 13.9 setup to uninstall it as I intenteded to install CCC 13.9. I opted for the "express" variant of the uninstall, which said it would uninstall all AMD software. During this, my screen went black, though the back light was still on and the mouse would appear if moved but would reset itself to the middle of the screen after a time, even if it was still being moved. After waiting for several minutes I turned the computer off (yes, there are a lot of actions I regret involved in this problem; I shouldn't have done any of this so blindly). When I reset the computer the HP symbol and loding animation came up, but then proceeded to a black screen like before. Also, I noted that every now and then the "ENG" and wifi bars would briefly flash on the screen. I tried to login in despite the screen being black, and, when change failed to occur, turned the computer off and on again, pressing the "F#" buttins to try and get into the boot menu to see if I could install a graphics driver from an external source. This failed to display. The black screen simply came up again. Interestingly, the HDD continued to click as if reading/writing no matter how long the computer was left. Eventually, now, the computer simply automatically shuts itself down after the HP symbol displays (though it does display the black screen first and the shutdown may not always happen).
The computer had a complete antivirus scan by Norton 360 only a few hours before this occured. When I first got this computer the AMD GPU was not in use at all, catalyst had to first be installed before even demanding games would switch from the Intel GPU. (It seems to have not initially had a driver.)
Is there some way i can install a driver from a disc or usb, maybe another computer?
Please help, I'm extremely worried.
Thank you!
