HP elitebook 8530p

I have several HP 8530p and get the NumLock & cap lock LED will Flash 5 times indicating a Board of Directors of the general system error. Bought new boards still getting the same problem.  Note all units start up for windows very well, but there is a delay of 10-15 sec in response to the hard disk during pc usage. The mouse is responsive in real-time, but once clink you on an element of lag appears.  Need suggestions on what to look for the problem, CPU, memory changed, fans, cooling system.  BIOS versions have been updated, I have demolished unit, cleaned up and added the new paste heat for CPU, GPU and added the copper shims in order to promote the best heat transfer. The System Diagnostics indicates material is ok.

After testing my computers, I found that the power support as cuasing the issue. I had tested all the 8530p with this same food tested that work very well on other fine HP systems. I changed my power adapter all the 3 8530 computer laptop p are working fine now.
