Just a thought - before going to Geek Squad and paying an arm and a leg, I would call around to your local computer repair shops - one will likely let you bring your computer in and test it on their diagnostic boxes for free - or at least for really cheap (not more than $5).
Also, The_Other_One - how could he upgrade his board BIOS? All I know is to put another (supported) processor on the board, reapply the paste, heatsink and fan, boot it up, flash BIOS and then reinstall his new processor?
Is there an easier way?
BTW - a local computer repair shop might let you do all that at their shop for free or cheap too...
