How to Troubleshoot Computer RAM
If you have multiple RAM modules, you can try removing one pair or one stick. You need to make sure you still have enough RAM on the motherboard to boot the computer–which will generally be 128 MB. Be sure to take precautions when removing computer modules, such as make sure the computer is off and unplugged, work on a stable flat surface and be wary of ESD (Electrostatic Discharge).
If you are able to narrow the problem down to a particular memory module, you should replace it immediately. If you cannot isolate the bad stick, you will need to run a program called memtest86 to scan the memory for errors. Typically, this test can take several hours. If you have an issue with your RAM, memtest86 will show it.
If the above techniques fail to solve your issue with STOP 0x00000050 PAGE_FAULT_IN_NON_PAGED_AREA error, try removing any unnecessary components inside the PC and see it that solves the issue. If the problem still persists, be sure to join our free computer repair forums and let us know.
