If you delete that file, you need to put the new copy in before you shut down, otherwise your PC will not boot. At this point you need to reinstall Windows, or do a repair installation. It wont work because it says the NTFS driver is missing right? NTFS stands for New Technology File System, that is how windows organizes your hard drive. If it doesn't have the drivers to read that filing system, you can't run windows period. Reinstall.
As for the computer restarting... once you reinstall, go to the windows website and manually download ALL updates and patches for windows. Although it mentions win32.sys, I dont think that is the problem. Even if you reformat and reinstall, and that doesn't fix the problem, I think i have a really good idea what is going on here.
I read an article by a PC repair technician about a year ago, it described a computer in a workshop that kept restarting itself at random times. Well, as it turns out, the computer on the inside was completely filthy. All of the fumes and smoke from the workshop accumlated inside and condensated into a grease of some sort onto the components. At some point a stray charge would hit the grease and go where it wasn't supposed to go, and viola! A restart. He disassembled the computer and throughly cleaned each component, reassembled, and it worked like brand new again.
So it might be that there is some serious gunk inside the case. However, if you open the case while the computer is under warranty, you void the warranty.
In short, if a reinstall doesn't work, ship it back.
