I'm not great with computers, I admit up front.
Basically my laptop got infected by some nasties last year (around Feb) and I managed to purge what I could and installed a few different anti-virus softwares. Since then its worked intermittently--freezing a lot and taking me all over the place when I search for things using different search engines (google, bing etc). My techie friend had a go at it the last week, cleaning it out and reinstalling stuff and so on. Since then its worked much better although I intend to use it less for the intenet and more for its Word programmes and so on.
Today suddenly its refusing to start. I turn it on and it takes me through wanting to repair files and the like, but when I select that option it randomly shuts down at any given moment (during the repair, after, there's no pattern). If I try to start Windows normally it just goes round in circles and takes me back to the screen asking if I want to start Windows normally.
I know its pretty tough to diagnose and advise on something like this without seeing the offending machine, but does anyone have any ideas? Any advice greatly appreciated!
