Question PC tries to open game then shuts off then goes into boot loop

[Ethan-w2003]

I just put together a build with a i5 760, gigabyte h55m with rx 570 4gb, and some old 1200w powersupply idk the brand, but i start up my pc and its running fine, i go to open a steam game or fortnite but i havent even played the game yet and it shuts down on me and then tries to start up but then goes into a boot loop, the only way to get out of that boot loop is by clearing the cmos, however i have done this about 5 times and it happens everytime i try to open a game. I dont know if it a cpu, mobo, psu, gpu problem.
PLEASE HELP!!

Was this a fresh install of Windows? Also, find out that exact PSU rather than "I don't know."

This wasnt a fresh install, how ever it was in my other pc that was working fine. And now the games load up and i can play for around 10 mins and my computer just shuts off. Is this usually a psu problem. Also i cant find the actual brand of psu, It just says POWER 1200w

Sudden shutdowns like this are typically temperatures or power supply. Can you take pictures of the power supply and all the information on them and upload them? It's quite necessary to know this information.

A PSU that says Power 1200w would be very heavy and would have some brand name on it. You may have to take off both sides of the case to see the name but there will be one. If there is No name or model number, then that PSU should be used as a door stop.

You need to do a fresh installation of windows on the new PC.

This is what? I don't see any pictures or info, so I can't comment on it.

As noted above, you also needed a fresh install. Operating systems aren't Lego; swapping them from system to system is highly unrecommended and it can cause all sorts of strange problems.
