Recently upgraded my old i5 cpu to a new i7. On startup with the new i7 all fans and lights turn on in the pc, but after about half a second it all shuts down. It doesnt attempt to restart or anything afterwards but rather stays off. I have switched back to the old cpu temporarily and the pc continues to work fine. I have updated the BIOS for my motherboard to the version which includes i7 support. Im not sure what next step to take from here.
