I've just bought a Q6600 today to replace an E2160 in my Gigabyte GA-P35-DS3. But after I installed the Q6600 and started the PC, it just kept resetting over and over. It turns on and runs for a few seconds, then resets and does the same thing (the fans run, no weird beeping). When I changed back to the E2160 everything ran fine again. The only thing I can think of is that the Q6600 is faulty. Is this correct?
