I had a laptop with 2 sticks of 4 gigs of DDR3 RAM, but it is temporarily broken, so I took a stick out from it and installed it into my other laptop. Lately though, it has been given me a lot of BSODs, usually related to RAM, such as "page fault in non-paged area". Is that because the RAM is incompatible? I would have thought that if it didn't work properly, my computer wouldn't have started at all. I should also mention that the RAM is working fine in the new laptop. Let me know if you need more information (frequency, computer model, etc.).
