computer is stopping

 My 10-year-old Windows 10 computer is stopping lately in the middle of use. The mouse just freezes. I am unable to get any response. ESC or cntr+alt+del have no effect. I can hold the power button for 10 seconds and it will shutdown. After the shutdown, the computer will power up and work for several hours. I did find plenty of dust under the processor fan and cleaned it off. I removed the fan for cleaning. The fan sits on top of the processor cooling fins. ???? Hopefully????
