hm, actually i don't think the mobo is in a bad position, i'll check it..... i mostly think that it's my bios that doesn't support conroe maybe, i'm gonna install a pd805 and flash to the 0903 bios version, then i'll reinstall again the conroe and check if everything works.
Is this beta bios supposed to work fine with B2 revision (official conroe release)?
I've read on the site that the official conroe B2 revision may only work with 0801 and above..... i probably have 0701...
