Laptop will not boot

I was using my laptop last night and it was working OK when all of a sudden a problem occurred. A single box came stating there was a problem and box stating restore

I pressed that but too no avail

I turned the computer off and rebooted but only the HP sign came up followed by the spinning broken line circle however would not boot up and remained black screen. I tried to reboot five times. I ran the quick fault finding system which showed all good and only half the long check because it was 9 hours and 25 minutes and still have four hour to go

I remember seeing my mircro trend virus software only one hour before saying everything was good

the only difference I can think of was; putting litecoin into a electrum wallet which I done before with no issues
