It's alright, I think I will return the GTX 650 and get a 460, people seem to have fewer issues with it. If I understand correctly it is due to the 650s memory needs that I need the DSDT override, but with a 460 it should work normally.

If I do not do anything right after adding QWord the compilation says that is it complete, but has a line above it that states "Maximum error count <200> exceeded." The AML file created is 0 KB so I do not think it would allow me any other way.

I just did the BIOS update and tried your method again. Here is a screenshot step by step process, but it lead to the same BSOD error as before.

I just tried and followed your guide again, the programs seemed to compile (but with 140 errors and 5 warnings) then the asl successfully overrode. The issue for me came from the reboot, after a reboot I would get a very fast BSOD just as the WIndows dots are spinning around. I got a video snapshot of the issue and its 0x000000A5 "The BIOS in this system is not fully ACPI compliant. Please contact your system vendor for an updated BIOS"

I thought I had the most recent BIOS, but I will now update it and see if that helps in any way.

Could someone who has successfully gotten past error 12 please help me get past mine? I have the card already installed with drivers and everything, but it will not run due to error 12. I have tried doing the DSDT override but that leads to a BSOD with the ACPI error. If I try and boot with the card plugged in then I just get a black screen from the very start. I can post screenshots of any of my steps to get some input on where I am going wrong.
