Alright, new installation checks out. The fact that you still have problems points to either the RAM or your CPU. If the system is still under warranty, I would advise having it inspected and repaired. If it is no longer under warranty, proceed to the next steps.


Test your RAM modules and slots as follows:
  1. Shut down and turn off your computer.
  2. Unplug all power sources to the tower (unplug the power from the outlet/surge protector or PSU).
  3. Hold down the power button for 30 seconds (for your safety and the safety of the components) to close the circuit and drain all power from components.
  4. Remove the RAM panel.
  5. Remove all but one memory module making sure you are grounded while doing so.
  6. Replace the casing and put the remaining memory modules in a safe, static free environment.
  7. If the problem persists, repeat steps 1-4 and move the memory module to another slot (while staying grounded, of course).


Do this until all slots have been tested. If all slots fail, the memory module may be bad. Test with one of the remaining modules. Continue one module at a time in one slot at a time until you find a good module and good slot. Test remaining modules in the good slot, test good modules in other slots to find bad slots, etc.


Test by doing the blend tests with Prime95 or Orthos.
