Inspiron 3 years old with Window7. System freezes or screen goes blank. Need to turn off and then back on with 'Normal windows load'. It may then work for a few hours or a few minutes. Dell did some checking and said it is not hardware but software problem. Need to buy service contract for them to fix. Based on the cost it would be better for me to buy a new one which would give me windows 10 included whenever it comes out.
So anyone know how to fix this?
