3) Run memtest86+ version 5.01 for at least 8 passes. Memtest86+ - Advanced Memory Diagnostic Tool
This may take hours so plan to run it overnight.
Please make sure you use the Memtest86+ version 5.01 with the link below.
Memtest86+ - Advanced Memory Diagnostic Tool
The testing is done not by time but by passes.
The more passes the better.
There are a significant number of false negatives if fewer than 8 passes are made.
A false negative is a test pass when there is malfunctioning RAM.
There is 8 GB of RAM on the computer.
Memtest86+ version 5.01 testing takes approximately 1 - 2 hours /GB RAM
Just 1 error is a fail and you can abort testing.
Then test 1 RAM module at a time in the same DIMM each for 8 or more passes.
When Memtest86+ has completed 8 or more passes use a camera or smart phone camera to take a picture and post an image into the thread.
