Every now and then(sometimes gaming sometimes browsing the web) my computer will randomly freeze and the screen wil go grey with darker grey lines(sound keeps going for about 5 seconds). I have replaced my psu recently so i do not believe it is that. I have allso had a problem with starting my computer recently: sometimes if i turn it of after a long gaming session it wont turn on until i leave it for about 1 minute, if i do try to turn it on it will come on but i have never heard the startup sound and the screen always remains without input.
problem happened on my old windows 7 install and still on my windows 10 install
