My computer has been running fine for months on end since purchase back last year. The PC is regularly cleaned, dusted etc. And everything is always up to date! I haven’t overclocked anything but I always make sure everything is always up to date such as drivers etc. No hardware is failing as I believe but games like PUBG & Fortnite suffer with screen freezing or crashes completely. This may just be the games themselve but I’m worried it’s not! Anything I should check?
