I moved my Asus PT6 Deluxe V2 motherboard into a new case and fitted a new cooler to the CPU (i7 920) and the thing refuses to boot. I always take care when handling components and to ensure the board wasn't shorting I removed it from the case and tried booting it on a bench with a single stick or ram and a graphics card only but nothing. I have tested the PSU is outputting the correct voltages with a PSU tester and that's fine. But there isn't even a beep out of the temporary speaker I fitted. The CPU fan spins up as does he graphics card and the on-board on/off and reset switches light up but it won't POST. Having tried 3 different sticks of ram and 2 different graphics cards I can only assume either the CPU or motherboard is damaged in some way. Is there a way to tell which one it might be?
