I think it may be very useful to post this, as I have seen more than a few people that just don't keep their PC's clean on the inside .Where it counts. So many issues can be prevented by simply opening it up at least every 3 months and using canned air, blow out the CPU heatsink & fan, the exhaust fan/fans, the intake area & fan if it has one, and the RAM, and chipset area. A $3-$4 can of air is cheap insurance if used regularly. The PC's biggest enemy is Heat! I hope this thread becomes useful to anyone out there in "Cyberland".
