Question My pc crashes playing call of duty warzone

[mperez1017]

i've had issues with call of duty warzone and cant seem to find out what is wrong with my pc i believe its something to do with the gpu. ive done a cpu burner test and my pc doesnt crash at all. I play hours of league of legends with multiple google chrome tabs open nothing. ive also crashed in valorant once or twice. Ive test my psu with a digital multimeter and everything looks good. I tried to gpu benchmark using furmark and it instantly crashes.
specs are
i5 6500
450w psu
motherboard gigabyte gaming-7 z170
16gb ddr4 ram
10603gb gpu

what your psu 12v rating?

Don’t understand what you mean but when testing the psu I checked the 24 connector specifically and made sure everything corresponded correctly to a diagram online.

mperez1017 What is the manufacturer and model number of your power supply? When the PC "crashes" what happens? Does it reboot? What exactly happens?
