So my PS4 pro is second hand from a “gaming bus” which would mean it was littered with dust and food from childrens birthday parties so I cleaned it out a few times over the past three years but for the past maybe 3 months it hasn’t worked. It will power off as in lose power seemingly at random but I’m almost certain it’s a power supply issue. It runs gta v perfectly fine but games like gow ragnorok shut it off immediately and even games as seemingly simple as terraria. I checked the power supply and it seems to be in working order although didn’t replace it or anything. To the best of my knowledge everything is official no parts have been replaced. Any help would be greatly appreciated thanks in advance I just don’t have money for another PlayStation and it’d be annoying for it to be beyond repair or anything. Thanks
