well thats something I really could'nt tell you.I guess you would have to work out how much juice your pc is using and take it from there.The documentation that came with the chip should tell you the voltage needed but all that is way out of my depth.
The only other thing you could try is the old process of elimination.Slowly take things out one by one and try booting up.Dont go as far as taking your chip out but try taking out a few PCI cards and then your graphics and try booting after each one.Of course theres also the possibility that something is not right in your BIOS,but again am not experienced enough to go don't that road.
Hope you get the help you need soon!
