I received a P35-DS4 and I think it's DOA. With or without hardware installed it always gives 3 beeps, then a pause and then it gives another 7 (making a total of 10). PSU is tested and proven to be working fine. I tried resetting the CMOS and reinstalling the cables: still the same. There is nothing shorting. I pushed the reboot button many many time, but to no avail.

Is this a known issue, or is it just faulty?
