Download a copy of memtest86 and let it run overnight. Only then will you know that your memory is good. Pretty much all other memory tests are too superficial to be useful.
I recently got another stick of RAM for my pc to make it run a little better. I made sure to buy the exact same one. Then ran that windows mem test on it and there is no errors on it, nor did it fail any of the tests on extended version. The RAM stick alone works smooth if it is in the first RAM slot as good as my old one.
I started to think it was a prob with the 2nd Slot. So out of curiousity I placed it on the 3rd slot and got the screen where it prompts u to start in safe mode or last saved config. etc etc and then it said I had a missing or corrupt
' \Windows\System32\Config\System '
It suggested that I place the recovery cd and press 'r' when i did so it just took me to this screen where i can partition my harddrive and/or install windows on it. I've never had a problem like this before so any help / insight into the situation would be helpful. Thanks in advance.
