i bought this mobo a month ago with:
amd phenom ii 965 BE
nvdia gt 9600
kingston hyper x blue 2x4gb
xilence 700watt psu
seagate 500gb hd

everything worked great without having any problem with my pc..i first upgrade my gpu with an asus gtx 650 direct cu with no problems...every single part worked fine until 3 days before when i upgrade for the second time my gpu with an evga gtx 660 sc edition...i closed the pc turned everything off unplugged the psu wire opened my pc unplugged the mobo,cpu,hd,optical drive wires and one ram of two...i put in my gtx 660 tried to opened the pc but nothing happened only a black screen sometimes with a cursor at the top left on my screen...i unplugged the wires put them back again change ram slots tried another ram another hd but same again...the only thing that's happening is one sort beep sound and the DRAM_LED flashlight flashes two times..i pressed the MemOK! button but no bios appeared again...the keyboard doesn't seem to work too i pressed num lock,caps lock but nothing....the mobo also shows the green light that meens POST ok and the fans works...i'm very confused...i thougth it's the mobo or the psu but i'm not sure any ideas?
