Having issues with my mom's dell.At first when I checked it out last week lights 3 and 4 were lit on the indicator. The system was running two 1Ghz sticks. I took one out and the system was able to post into windows.I figured the other stick must be 755 error codes bad. I bought ram, used but should still be covered under g skill warranty. Installed and then nothing. No post.I switch around the ram, and it posts but then I get a BSOD. Something about bad pool header. I try switching in and out the old ram, the new ram, in various configurations.Right now, it's running one stick of 1Ghz, the old ram. Some dell diagnostic "preboot system assessment" is running.How can I see whether I have a motherboard problem or a ram issue? I do not have another system to test ddr2 ram on. · actions · 2013-Nov-9 3:04 pm · asdfdfdfdfdfPremium Memberjoin:2012-05-09kudos:3 asdfdfdfdfdf Premium Member 2013-Nov-9 3:29 pm When you say you switched around the ram did you swap the stick you took out for the stick that was able to boot (i.e. did you try both sticks individually in the first slot)? Did they both boot alone in that particular slot?Did you try both sticks in the other 2 slots that were not used before? · actions · 2013-N
