PC resetting during games

[CrazyWhiteShow]

PC resets after 20~ minutes of playing games (except league of legends), it started happening after I replaced the PSU (og psu was some no name dont know what the voltage was) with a corsair CX850M and replaced the gpu (was a gt 720) with an rx 470). the gpu is also (at least in counterstrike) at 0% usage most of the time, sometimes going to %100 for a split second even though im geting well above 100fps, but for some reason in spectator mode a get lots of stuttering. Tried to fix it by doing a fresh install of windows 10 but that didnt work.

 

old System:

cpu:FX-4300

mobo:idk

cooler:stock

ram:some old, edgy stick of ddr3 4gb

storage: 1tb hdd 

gpu:gt 720

psu: no name psu(idk the wattage)

 

New System: 

cpu:FX-4300

mobo:idk

cooler:stock

ram:some old, edgy stick of ddr3 4gb

storage: 1tb hdd 

gpu:rx 470

psu: corsair CX850M

I would suggest resetting the BIOS if you can find a way to do that if that doesn't work then maybe monitor your temps the next time that you are playing games and see if the CPU is overheating. I am not sure why a PSU Swap would do something like this. If nothing else works, I would suggest going through the RMA Process for your PSU since it could be defective.

cant monitor cpu temps well says its at around 0c all of the time, but how do you re-set the bios?
