Help, computer won't boot

Hi, when ever I try to run my computer it won't boot, it says startup repair can't repair this computer, so I went to diagnosis and repair details and this is what it says

Boot critical file c:\windows\system32\drivers\42c84745e8d5975.sys is corrupt.

Repair action: file repair
Result: Failed. Error code = 0x2
Time taken = 4618 ms

Repair action: System files integrity check and repair
Result: Failed. Error code = 0x490
Time taken taken = 588888 ms

It's not possible that in one hour you could have worked through all of the steps to disinfect, repair system files, rescue files then if necessary run Factory Recovery or Clean Reinstall.

If you want it fixed you need to do the steps or take it to a shop - there are no shortcuts. We'll know you are actually doing them when you interact with us on your progress.

Ok, so I went through the steps, and tried using the bootable antivirus thing to help, and it hasn't because everytime I try to boot it something goes wrong, and I'm not sure if my computer supports anything like virtual drives and other external programs.

What you mention has nothing to do with correctly booting a bootable AV to scan your HD which can be done on any PC with a working CD drive or which supports flash stick boot.

We need the actual error message or exactly what happens as we cannot troubleshoot "something goes wrong."

You have two things you can do,

Method one:
1: The computer with the problem, you must know what OS version it's running, (eg. 64bit or 32bit of Windows 7)
2: Then go to any other computer that has windows 7 **bit (** stands for the number of your previous not working computer's bit. eg. 32bit)
3: Insert a blank CD/DVD in your computer (minimum 500 mb)
4: Go to start in the other computer, and type in "create a system repair disc" and press Enter
5: Then Select your CD/DVD drive in the select option and click Create disc
6: Restart your computer
7: Boot from your CD/DVD by press F12 in your keyboard while booting up. (Might be different key for other computer. If it's different for you, go into your bios and enable your CD/DVD to boot first)
8: It should say "Windows is loading files" like how you first were to install Windows 7
9: Then you should know what to do. If not, tell me and I will tell you next steps.

Method two

1. Get your Microsoft Windows 7 installation disk ready.
2. Boot from it. Then follow step 7 in method 1.

Let me know if it helps you. If you succeed in these steps, then click on "Startup Repair" in the option when the disk loads up. It should fix the problems and ask you to restart the computer.
