Relatively recently I got a ASUS ROG G20, after getting it I noticed I wasn’t able to run games well I was a bit confused so I looked into and I was using integrated graphics, no matter what I tried I couldn’t switch it to the gtx 750 inside it I checked it was getting power and seemed fine later on I decided I’d try a different card so I bought a cheap gtx 460 and same thing gets power seems fine but I can’t use it.
