TOP tells you that your CPU usage can be the cause i think: "Cpu(s): 85.1%us, 7.6%sy," Try to go into WHM / Server Status / Apache Status and see the processes... any suspicious? one IP many times? Also check WHM / System health / Process manager if nothing strange, try "ps auxf" try "top -c" then try: "iotop -a" . If dont have iotop, install it. It will tell you which processes using the HDD. also check your log files in /var/log (tail logfilename -n50) --- Have doubts? try to keep calm and type proper phrasses/questions into google
