Elitebook 840

Hello everyone,
My laptop hp elitebook 840, 16GB Ram wont start when turning power on but I hear 5 beeps and caplock blinks
I tried following steps until now and nothing worked
-took ram out, changed their position reconnected
-took battery and cmos out and reconnected
-took hard drive out and reconnected
I cannot even open bios setting , please give your valuable suggestions what else i can try or replace?
