Hi all, I followed the guidance on this board prior to posting these dump files. This is a very strange problem and I'm having trouble figuring it out. Here is the short version: I have windows 7 x64. I have a i7 processor with 6 gb RAM (3x2GB) After having the computer up and running for a few weeks and went out of town and left my computer off. When I came back and tried to boot it BSOD. I messed around with it for a while. Ran Memtest 86 with no errors for 24 hours and it finally booted. I left town again for a week. Came back and same thing. BSOD on boot. This time Memtest spit out ALL errors and no passes. It also only registered 2 sticks of mem (4gb). I ran the repair console and windows finally booted. Then I ran Memtest again for 24 hours with no errors. I ran LinX for 20 passes with no errors. I did a chkdsk with no errors. Then I left my computer off for a few days and turned it back on.....BSOD. It was then I found these boards and saw you could get the DMP files. To get my computer to boot this time, I removed all but 1 of the memory sticks. It booted fine. I powered down and put all 3 sticks in....also booted fine. I have tried each stick in all the slots single and together. It seems like after the computer has been "on for a while" that there are no issues. I only had 2 of them for some reason. I analyzed them, but was unsure how to interpret the results. I have attached them to this post. There are just a few things that don't make sense to me about this problem: I only get this problem on boot after long periods of power off. Once I get windows booted, I can stress test the system with no errors. Problem only seemingly started a few weeks after I put the system together. It will boot with one stick of RAM in any slot, but not with all 3. It will boot with all 3 after I get it to boot with 1. Please help me, I am at a loss here. I had to .zip the dmp files because they were over the 200kb size limit.
