AsRock B450 Pro4
AM4, AMD B450, ATX
Hi i am building a system together with the mainboard asrock b450 pro4 (ATX) g skill ddr4 8gb And a ryzen 3 2200g power supply bequiet straightpower 400watt My problem is now that the mainboard ran the first day perfectly with two graphics cards and on the other day it has suddenly shown no more picture then I have replaced all the usual things and checked but none of the said hardware was broken then I sent the mainboard back to the manufacturer and they write that they have found no errors and sent me back again. Then i thought ok then maybe the fault has been fixed somehow i plug everything in i turn the system back on and it shows picture with integrated graphics card then i plug the first gpu back in it still shows picture i plug the second gpu in and it doesn't show anything then i unplug the second gpu and it still shows picture. second gpu out again and it also shows nothing and then the first gpu out and it shows nothing so exactly the same error as before no matter what i do it shows nothing and i am getting desperate because i have changed all hardware to something i had lying around but it just won't work And apparently no one on the internet has the same problem.
