I recently bought a new graphics card to my computer and after that there is some games my pc can no longer run, it worked just fine playing gta5 with my old graphics card but when I do now my pc just turns off and then automatically turns on. Thanks!

what are the specs of the PC?

it could be you don't have enough power to run gpu as a newer card should easily play GTA5 as I assume its better than old one.
