My PC has been restarting itself and not posting for a couple weeks now, from my past experiance these issues should lead to the ram. However, I tested each stick individually for 2 hours and got no memtest errors, I also rotated slots for this testing. What confuses me is when i run the test with both sticks of ram in at the same time, i get errors on test 5. Would this lead the problem to the motherboard or cpu?
