Hey guys I have an Emachines computer and I'm running a 64bit version of windows 7. I have recently got a horrible virus that I have literally tried everything possible to get rid of other than reinstalling windows. My only problem is that the computer when I purchased it didn't come with a windows cd. It came with the installation on the computer. I was wondering if there are any hidden partitions or any way of repairing my computer. What seems to be the problem is I think that the installer on the computer isn't completely repairing the registry. I just need some way of getting a new installation of windows on my pc. Oh and the serial for windows was on the bottom of my computer so it's rubbed off in time, does the computer save this somewhere on the hard drive?
