  1. You've not mentioned that are you using x64 version of windows or otherwise. Anyhow, pl download MalwareBytes from its site and run it. Most likely this is malware attack on your notebook.

    So you have Windows 7 and Windows 8 installed to dual boot? Is that what the title of your post means?

    Regardless - please provide the other specs of your laptop, or at least the full model number so we can look those up. And where do you mean "available" - do you mean that's what shows as Free Physical Memory in the task manager? Or that's what shows in the system info box? Provide either a screenshot or detailed description of exactly where this information is showing.
