Hamood_d10, please let me know if this is new integration or if this behavior started recently?
If you restart the system without memory, are you getting 3 beeps?
Please keep in mind the blue DIMMs needs to be populated first. Would you please test one memory stick at the time on each blue DIMM, restart the system and check if it is being recognized? I just want to find out if there is a defective slot on the board.
Then, if you are able to boot using 1 memory stick, please add a second one using only the blue DIMMs. If both memory sticks work fine, try to clear the settings on the BIOS taking the battery out for 5 minutes then put it back in the same position, boot to the BIOS and set the data and time and give it a try with both memory sticks.
