Hi i have made a boo boo ! i upgraded my c2d e6600 cpu to a c2d q6600 a nice 2 mimuite upgrade but after about 2 mins the machine shuts down ..damm when i put the e6600 back in everything is fine . the mother board is an asus p5vd2-x which supports socket 775 c2d cpus but does not actually mention the quads ? so if i am stuck with having to get a new motherboard what do you recommend ? i need a cheap board as i didnt expect the extra cost and i need a board that will take 2 x ide hard drives & i sata hd & 2 ide dvd drives & a sound card & nees to be pci-e. i am in the uk and tend to use ebyer.co.uk so could someone please give me some options as my head is fried with all this at the moment.
