Need computer maintenance help

[Deb]

We really need to dust inside our computer and replace a fan. I'm tempted to use a hairdryer or vacuum instead of canned air for dusting but will get canned air if need be.

Do I dare replace the fan w/o one of those wrist things for static?

Thanks

1. just be careful with the vacuum

and no, just touch the case before you work.

2. your help

Can air is great..watch it though it really blows the dust everywhere. Your safe if the Power is off and Power plug is pulled out. you dont need the static wrist thing if you touch the metal case while you clean it...touching case ground you.
Note how the old fan plugs in and replace it with another.

3. Thanks so much

I think we'd better get canned air, my fan just started making a different pitched sound so we bought a new one but forgot the air.
