|Cleaning out dust is always a goof thing (part of annual maintenance), but if it does this at start up it is probably something else. You can install Speedfan or similar program and monitor your internal temperatures to see if it is heat related and verify if this is needed to solve the problem. I do believe that your problem is a bad memory stick or possibly other hardware issue. To check your memory use Memtest86 and run the full set of tests, or until you get errors. If you get any errors you will need to replace the memory, but you can rerun it with one stick at a time to find the bad one, though if you are using dual channel memory you should replace them as a pair. Post back results.|
You have to be a little bit crazy to keep you from going insane.
