Sorry that i forgot to mention all of that.
I am using the MSI h81-p33 with Windows 10 the newest insider preview(16257.1). The GPU driver is version 384.94. Not sure what PSU im using but its real 500w. And i have an i3-4160. This is the only card I am using at the moment because I am planning to buy an RX 570 and I want to make sure the riser works properly. Yes, it works when its plugged in the PCI x16 slot without a riser. I tried connecting the riser to the x16 slot but it did not work, and I made sure that i plugged it in the right way.
