System32 help IMMEDIATELY!
Alright, so well here's the story of my stupidity
I was bored and I downloaded apparently a hacked version of Halo 2, and my girlfriend was over so I was distracted by her trying to install it. It told me to put an mf.dll into my System's 32 file, and so I did but not before backing up the original one, and after that was done it said to go back and click on the System32 folder and do "Switch user" or whatever it was, I didn't know what that meant, and when doing that it came up with the command prompt saying physical memory dump. and that completed and then when Halo didn't work I just deleted it and reswitched the dll files in the system32 folder. It was working fine for hours - Until I restarted my computer. It would come to the login screen, I'd put in my information, and a blue screen with a lot of error text will pop up, and my system would restart automatically. And then I tried reformatting my computer completely erasing everything - that didn't work. Even tried taking out the batter inside the computer to erase the BIOS or whatever, that didn't work. How do you fix a computer that can't even get to the desktop screen? PLEASE HELP! I don't know what to do and I'm at my wits end, the computer is a Gateway FX and is only 6 months years old, and it was well over 1000 dollars and for me that's a lot of money. So any help is appreciated!
