I have experienced this problem on my desktop computer for some time now and have learned to live with it. I've done the usual tests such as memtest, hard drive tests and driver updates to name but a few. I am now considering replacing the motherboard as this is the oldest part of the machine. Before I do I would like to know if anyone as any further ideas. I run Windows 7 Ultimate with 4mb of ram, 3.2ghz processor with 2 500gb hard drives.
Aquariel, 1 to 3 could be a possibility because all are a good 8 years old now. I have however checked the ventilation which seems fine. 4 I have no cards fitted I use on board graphics and sound.
SlackAlice I will check the error code next time, I have looked at the crash dump all of which makes no sense to me. I remember that each time the possible cause mentioned is ntoskrnl.exe though.
