Yeah i was afraid of that, I am actually ordering a new motherboard completely if this is the case. I have an Athlon II processor that i cant use, so I was think just a new motherboard completely, will fix this and I could use the new processor.
good choice for the asrock 970 board; be sure it will fit your dell case; many have a funky half #$%^ board design; a cross between atx and micro atx. You may also need a new windows coa; dell windows installations won't run with non dell bios'. The dell windows installation actually checks for a small bios string everytime you power on.
