Computer had been working fine for 6-7 months until last month or so. While playing games it will freeze for 5-10 seconds a few times over then crash my computer. Everything else works fine and it I've run GPU and CPU tests and there is no overheating or faults it seems. I've cleaned wiped the computer so its not a virus. Honeslty lost as what it could be apart from a faulty GPU. Any help would be great thanks.
