I installed Windows ages ago and it worked fine for quite a while. Then I kept getting pop-ups saying I had spyware, so I ran some virus scanners and they caught the problem. Then I disconnected from the internet on the Windows partition as I realised I didn't really need it. Anyway, after that, which was a couple of days before this problem started, I could load the Windows partition perfectly. I didn't get any more pop-ups, everything was as it was when I first started. Then one day, I tried to load up Windows, but it asked me to log-in with my username and password. I thought this was strange because it has never asked me to do this before - I didn't even enter a password when I was installing it. So I left the password field blank, and clicked "OK". It seemed to log me on with no problem, but then a blue screen with white text on came up and the computer restarted in Mac (default) mode. The blue screen was only there for a split second so I couldn't read what it said on it. I think I caught something about "physical memory", but I can't be entirely sure. I tried restarting Windows in safe mode but it did the same thing. Now I don't know what to do, so please could you help me? I'm really not very tech-savvy, so please try to 'dumb-down' any instructions, so to speak! Thanks in advance. Also, my memory stick stopped working with the Mac partition a day or so after Windows stopped working. All the files got deleted from it, and there are all these strange files with names that seem to be in some sort of code. Is this a separate problem, or are they related in any way?
