BSOD - STOP: 0x0000006B - Won't boot in safe mode or from USB

Just a little background information:

I've used computers my entire life, but never encountered a problem such as this. I don't understand a lot of the jargon, so please forgive my ignorance. I just know how to use a computer...not fix them...but hopefully, with your help, that will change.

Prior to the BSOD:

I just upgraded from Vista to 7 and have been adding the typical programs to the hard drive such as avast!, CCleaner, Defraggler, etc. Well, avast! kept blocking websites such as Pandora and after trying to fix this problem and speaking with a customer service rep, I uninstalled it and downloaded AVG Anti Virus. AVG came with a few extra programs that I didn't want, so I uninstalled them, but kept AVG. I then scanned my laptop, deleted all the extra junk, defragged it and went to sleep. The computer was hibernating.

Come morning time, I downloaded Photoshop and proceeded to install it when I was prompted to restart my computer because another program required it. So...I restart it and I've been plagued by the BSOD ever since.

STOP: 0x0000006B

I've been doing some research and I can't fix it. I tried loading it in safe mode, but I keep getting the BSOD. I tried booting it from the same USB that I used to install Windows 7, but it keeps sending me to the installation screen. I tried multiple restore points, system repairs and booting it from the last successful configuration...NOTHING. I, somehow, was able to reach a menu that allowed me to choose which drivers I wanted to load, so I searched for the boot cache file to see if I could delete it, except it wasn't there.

I made the mistake of moving my business files from my external hard drive to my hard drive, instead of copying them, so re-installing Windows 7 (at this point) is out-of-the-question.

PLEASE...PLEASE HELP ME! I'll be online all night and will even call you if I must in order to fix this. Your help is greatly appreciated.

I can't even get past the splash screen. I'm on my girlfriend's computer. I can get to the splash screen, but the the BSOD pops up. Help?

As I stated in my first post, I still get the BSOD in safe mode.

When I try to boot from the USB that has Windows 7 on it, I still get the BSOD and the system repair does nothing. It says my computer can't be repaired.

"Startup Repair cannot repair this computer automatically"

Any ideas? Thanks for the help everyone!
