When you cleaned your processor, have you reapplied the thermal paste? Maybe your processor is overheating and it's now restarting the pc to protect itself.

You should check to see if your thermal paste is still creamy - which after 5 years it probably won't - because if it's dried up you HAVE to reapply it, otherwise at the very least the cpu will throttle in order to cool itself down.

And it can overheat 2 seconds after you turn the pc on if you'd just turned it off or if it'd just self rebooted because it will have overheated before.

If this doesn't work do as I did:
What I did was I booted using the Windows 7 disc and on the disk selection screen I completely deleted my system HDD and reinstalled on it. You can do the same with the Windows 10 disc/usb dongle.
