My PC suddenly won't boot windows 10. It loads as far as windows logo screen then screen goes blank and monitor message 'no signal'. I have managed to load in safe mode and checked device manager and have an exclamation mark next to monitor. Any ideas?
 
Managed to get it going last night, switched on this morning back to same problem. Got a bsod on second boot up with error nvlddmkm.sys. first boot up saw a really pixelated screen think it was trying to show the windows logo. Has the GPU failed? Installed all latest drivers etc
