Two days ago I bought a Sapphire TRI-X R9 290X (OC edition) to replace my GTX680. However, upon first installing the drivers I will get after 2 - 5 min from boot-up a blue screen with error code 0xa0000001. Closer inspection of the logbook and crach dump reveal Kernal power (41) and atikmdag.sys as the main culprit. Since then, I've tried numerous driver versions (all full clean install) to no avail. Furthermore, I even upgraded my PSU, disabled ULPS and clocked back my OCed CPU. Again, nothing helps. If I install my GTX680 back everything works as ever, no BSOD nothing.
However, the odd thing is that the R9 290X does work in my brother's PC (x58 chipset) and a almost identical system of a friend of mine. Something is messing with the drivers/the card in my system. Does anybody have any suggestions how to get this thing to work because it is very frustrating
