HP Compaq Elite 8300 All In One Startup Issue

I have a clients HP Compaq Elite 8300 AIO computer with a startup issue.

When we press the button to turn the computer on there is nothing that comes up on the screen, not even the BIOS screen.  If I leave the computer on then after about 45 seconds, the system fan starts winding up and getting quite fast.  Its as though the system is heating up and the fan is trying to cool it, but I cannot feel it to touch.

I then turn it off with the power button.  

If I take the power cable out then drain all residual power, then sometimes when I plug the power cable back in and turn on the system will start.  When it starts it works OK.  
But the next time you go to start it after a shut down it will not start.

I have upgraded the BIOS to version 3.02 successfully.

The computer was hardly ever turned off over the 3 years of its life.  So I am wondering if the System Board is degrading, or the onboard VGA is becoming faulty.

Out of every 5 times we attempt to start-up it will start up once maybe twice.

I have replaced the RAM and the hard drive but that makes no difference.

Anyone else encountered such an issue with the HP AIO??

It was also recently upgraded to Windows 10, but as the issue is a startup issue I have ruled that out as it seems to fail before the BIOS screen comes up even.
