Hi, I've bought got my computer yesterday, and it seemed alright, but it freezes completely after 15-20 minutes of gaming. Then I have to restart the computer for it to work again.

you bought it complete?

There is a warrant so take it back to the seller and have them fix it

I doubt your PSU strongly. Can you borrow a PSU from someone of a decent quality, like XFX, Seasonic, Corsair HX,TX series. If so then tryout the PSU first.
