I have an AMD RX 280 or HD 7900
(Looks like a RX 280 in real life, but my PC sees it as a HD 7900)
It bluescreens after starting windows, on occasion after Welcome screen(On the bluescreen I noticed atikmpag.sys). But it's only happening on This Computer, I tried it on my dad's PC and it worked. So now I have no other option than the old HD 5770 with 1GB..... I can't play Mafia III :( Any help?
 
Solution
Sounds like your power supply cant handle the video card. If your old 5770 worked and the 7900 worked on your dads it has to be the PSU. I suggest getting a new powersupply.
