[nach0 party]

ok well someone directed me back to my old thread because they were very bright and noticed the name of the same person who started both threads so hell ill just continue my old one. either way i have another question about the 3870x2 that i bought say 2 months ago.
its still a headache, of course. in the past 2 months i ordered 2 different motherboards, 1 did not work with the card, RMA'ed it back to newegg, got the one i have now, it did not work (ATX main psu cable wouldn't go in correctly) and i just recieved my new motherboard.
Good news: the motherboard works
Bad news: the card does NOT work with the motherboard.
Motherboard name : DFI Lanparty 790fx
Newegg reference: Newegg.com - DFI LANPARTY DK 790FX-M2RS AM2+/AM2 AMD 790FX ATX AMD Motherboard - AMD Motherboards
I even checked all over the web, it was seemingly common knowledge that the 3870x2 works with this motherboard. the brand i ordered was powercolor, maybe they just don't work well with systems or what but any help / suggestions aka: update bios, clear cmos (tried that actually), or if theres anything simpler before updating my bios that i should check for please let me know im just about ready to sell this piece of junk
