How can you accuse anyone here of leaving you hanging when this is response #112?
You obviously do not know what you are doing and don't seem to heed the advice that has been given.
I suggest you copy your personal files to an external location like CDR and then either try to perform a system restore using a restore point dating back to before this latest problem. If that doesn't work, then re-install Windows.
As far as your current system goes, it is not a gaming platform and never will be. You would be best off to get someone to assemble one for you.
You need a PSU, graphics card and more memory, at the very least.
Now, did you actually read the path to all those references? What is your Q drive? Some external, like a flash drive perhaps? If it isn't present when you run the scan it can't find those references.
You may well be infected. Why can't you run Safe Mode? Are you using a USB keyboard and get no response when trying F8? If so, use a PS/2 keyboard or the original USB keyboard, if it came with one.
