So I came home from work today and turned on my PC then went and opened a few windows etc.
When I came back my PC was running but I had a blank screen. I waited a bit before turning it off and on again.
I've done this a few times, when it starts up I see the BIOS menu, windows icon and loading spinner then it goes blank. I've once had a blue screen saying windows failed to load but not all the time. I left the blank screen for 10-15 mins and went to the shop thinking that windows may be very load to load but nothing.
Last thing I did last night was shut down and install update.
