ThinkCentre Edge SFF not booting - 2 beeps

Hi,

 

I have a ThinkCentre Edge SFF pc. I went to add some (compatible) RAM.

Upon reboot I now get 2 short beeps (black screen) then the system shuts down after about 10 seconds.

I have tried the ram in a different slot , reverted to the original ram, tried new ram but all to no avail.

 

Tried disconnecting everything one by one but no joy.

 

Any help would be greatly appreciated

Howard

I suggest reinstalling the original memory, and then doing a full CMOS reset.   In addition to moving the jumper for a  CMOS reset as detailed in the HMM, pull the battery, and press and hold the power switch multiple times with the power cord unplugged to drain the static charge.
