Hi Guys,

My PC build:
i7-2600
8GB DDR3 1600MHz
MSI R7870 Twin Frozr III
Asus Sabertooth P67 Rev3.0

So when i installed the Sabertooth today, my pc refused to boot and the vga led was turned on. Tried everything (removing battery, ram etc). But now i found out that the gpu does work when i plug it into the second PCI-E 2.0 port.
Funny though, the same happened to my other motherboard, MSI B75A-G43 Gaming, and it also only worked in the second slot. So, as i am new to socket 1155, is this common? How can i get the first to work?

Thanks

Okay, so now tried an nVidia GT 9600, and ***** ****, it worked! I don't know what to do anymore, because the 7870 just refuses to work in the first slot :(
