Hello everyone,

I have a Dell XPS 9530 which could not boot to OS (two beeps).  I discovered that it meant no RAM is detected.  After inserting two new memory cards (DDR3 as indicated from Spec), it still produces two beeps. This is what I did so far:

1. Drain the power by holding the power button for a while

2. Reseat the DIMM

3. There is no SSD card, but the HDD is not connected (missing cable)

Could you please tell me what else should i check to fix the beeping issue? 

Thanks
