Question Laptop rebooting continuously

[RPK1974]

When I power on my laptop it will keep rebooting continuously but when I power it on and hold the tab, space or caps key (any one of the keys) it will boot properly and work properly for hours but as soon as I release the key it will switch off and keep rebooting continuously I have tried everything in fact I have reinstalled Windows 10 also but still the same issue exist.

It is a Gateway GWTN156-1BL 15.6" Notebook Intel Core i5-1035G1 1.0GHz 16GB RAM 256GB SSD Windows 10 .
It was not damaged, suddenly one fine day this problem started. I don"t understand if its a software or hardware problem.

When you reinstalled Windows, was it a full, clean install?

Yes it was a full clean install and as I have mentioned earlier it boots and works absolutely fine if either the tab, space or tab key is pressed & once the key is released it will give the message slide to shut down and it will shut down immediately.
