Press and hold the power button so the fan goes off. There are no four short BIOS error beep codes for HP Desktop PCs released for. If any of your RAM goes undetected, also the chime doesnt happen and the only sound is of 3 concorrunt beeps then: 1. I've tried using 3 different sets of 16gb memory (all known good. Although if I put the sticks in 1 at a time (either slot), it boots up just fine. The odd thing is, if I put in 2 8GB sticks (correct type), it just does the 3 beep sequence (memory error). Some number of short beeps that are sounded by the BIOS upon startup when a memory, cache or processor error is encountered. On Mac, a startup beep represents issues with your memory or firmware.
