A client brought an HP probook-corei5

It turns on but won't display on monitor, 

i tried replacing the RAM severally, after many trials, it came up and works perfectly for hours.

When the client came for pick up it refuses to display. i have tried repeating the previous process but the problem still persists.

What is the full model of this probook?
Have you tried using an external monitor to see if this persists?  
Set the computer to boot into Safe Mode.
Open the Search charm and type in msconfig.
When System Configuration opens click/tap on Boot
Click/tap on Safe boot, then Apply, and OK.
See if the problem continues in Safe Mode.  Safe Mode uses a limited number of applications and drivers.  The graphics driver used in Safe Mode is a native Windows driver.  If the problem doesn't reoccur in Safe Mode the problem this would be an indication that the problem is driver related.
Look in the Device Manager to see if there are any yellow warning icons or red error icons under Display Adapters.


To open the Device Manager press press the Windows keywindowskey_zps092d5c75.png and the X key at the same time.  In the menu that opens select Device Manager.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.
