Hello, everybody, this is my first time here, so I hope I will be welcome and I've heard that here are people smart in tech. I'm not dumb in computers, I know a lot of stuff, but I literally haven't heard ANYTHING about this. So, here is the problem. Recently I built a new desktop PC for myself, so I decided to give my old one to my brother because it wasn't that bad and everything worked fine, it could run all the games he wanted etc. The computer was bought in 2011, and for 5 years everything was great when I gave it to my brother I cleaned the memory so it was faster and crap. I gave it to my brother, after a month or so it showed that the Windows is not genuine. I was like ''Dafuq?'', I don't have the code anymore. I restored it to an earlier point and it was fine for another two or so months. Then it went to a non-genuine version again, but this time I had no restore points for some reason. OK, that wasn't that big of a problem really, but then after some time my brother wanted to record some videos, so I downloaded AMD Radeon official software (it has an AMD Radeon HD videocard) and with all the recording stuff it asked to update drivers, so I looked that they were like 3 years old and updated. Then everything went to crap, the screen turned very, very dark (you can't see almost anything, only if you like glare from under you can see the outlines of the icons) and at first, I thought that the screen broke or something like that, so I connected an external monitor with a VGA cable and it worked. I tried to uninstall the drivers when it went to the Windows Basic drivers the built in screen was showing, but in low resolution and you can't run any games. I tried installing beta drivers, older drivers, nothing worked. Now my brother has a laptop with an external, old as ass Samsung SyncMaster hooked up to it. Can someone help, I dunno what to do! I can tell the stats of the computer, it has a 64-bit Windows 7 Home Premium, apparently non-genuine now.
