Well, I got a BSOD when playing two games, both seemed to be the same error. Then I got one just surfing the net. Previously I had just installed two more sticks of RAM to total 4GB. Each time a log was write and it did a memory dump but I do not where they are. So the memory could be the issue. Or the motherboard does not like 4GB but had no problem at the start.
The ram I had thought faulty and had failed a memtest from my end, when sent back where tested and found to be working fine. So ethier the motherboard memory sockets are faulty somehow or something else is up. I will do a quick memtest on the current two and then the next two, tonight/tomorrow and report back. But I'm not sure how reliable it will be. Any thing else to check?
