I have a computer running Windows 7 that has a weird problem: it's constantly showing the "blue screen of death", but only when the system is cold. If I leave it on for a while, after a couple blue screens/reboots, it starts to work normally, and doesn't show any other problems as long as I keep it on.
The blue screen is always of the same type: "MEMORY_MANAGEMENT". I let memtest run a couple of passes yesterday, but it didn't find any problem. I also ran a complete "chkdsk /B" (no errors) and recently switched the video card to a new one, but the problem was already happening before.
Although the problem seems to be related to the temperature (once the computer is "hot enough", the issue disappears), I don't live in a cold place at all (I live in a hot/dry city in Brazil). Computer starts at about 35 degrees celsius (according to the BIOS hardware monitor).
Is there any relation between failing memory and low temperature, or any other tests I could make? It's pretty hard to investigate this issue with common tests, because since they usually make the system hotter, the problem disappears once I start testing.
