I just assembled a new system and it does not power up. It as a Gigabyte m/b (P67A-UD3-B3). Did the following:
Power switch to m/b pins - check,
A/C power to PSU block - check,
CPU fan connected to m/b - check,
ATX 6-pin and ATX 24-pin on m/b connected - check.
What am I missing?Should I check the voltage out from the PSU? Do I need plastic standoffs between m/b and case? On my last system upgrade when I switched from conductive metal to plastic it powered up after similiar situation.
