Whenever my laptop is processing anything, if I touch any key or try to switch screens or close a screen it freezes, gives me the 'not responding' message, then makes the screen black and eventually I have to do a hard restart to get it back. It's happening about 5 time a day and is very frustrating as I need to use it a lot. It's only about a year and a half old.
Have scanned system with Avira and MBAM and nothing has been found.
I don't know how to do any diagnostic tests so if anyone recommends one could they please give basic instructions please.
Cheers!
