what is the best way to clean the insides of a computer? i have a 'megnetic' duster that i use to clean around the house. i was tempted to use it but i thought using it may build up static electricity. any suggestions on this? thanks.

The best way is to blow them out with an air compressor. I have one mounted in my store and I blow out customers computers all day with it. It makes it a lot easier and I think it's about the safest also. You can blow out fans, heat sinks, and inside floppy and CD drives. If you don't have a compressor available, use canned air, but keep it upright to avoid moisture. As you said, vaccuums can be dangerous because of the static charges that can build up Musky If the voices inside my head paid rent, I'd be rich!

Years ago I used to have a friendly local garage (auto repair shop) who would let me use their compressor and I'd just take it in there every 6 months and give it a blast! A small paint brush can also be used to gently loosen encrusted dust before using canned air.
