OK... I AM a computer tech and I can give you advice based on experience and training. First of all, if you want to clean out your computer, the ONLY way to safely do it is with canned air. It's really expensive, something like $4 or $5 at your local office supply store. IF, and only if you must reach your hands inside for anything a few things must be taken into account: ESD - Electrostatic discharge. No, this is not mumbo-jumbo it is very real and deadly to computer parts. If you remove the power cord from your PC you have effectively isolated it from natural ground (that little round hole on your electrical outlet) and ESD becomes MORE of a problem then believe it or not. With the power cord disconnected, grounding yourself off to the metal of the case is OK, but it is not fool proof and actually not advised. People do it all the time... I have done it and have not suffered immediate consequences that I am aware of. However it does not take you actually feeling a shock from static to cause a problem. I will not insert all the facts and figures here because I do not know them off the top of my head, but you can damage a computer part or drastically shorten the life of a part and not even know you have done it. Also, keep in mind that some warranties for a part will be void if it was ESD related. If you must change a card or some other electrical component then I would unplug the machine and the monitor and phone line or network line. The printer might be a good idea, but if you unplug that you shouldn't have any problem. The keyboard and mouse do not retain any electrical charge and therefore are harmless. There are devices that can connect you (it really is you that must be grounded AND the machine if you can)directly to a grounding source so that ESD will not be an issue... however, if you don't know what you are doing then have someone that knows what they are doing install your part. Look, I am not drumming up work for techies... but the fact is that it is your machine and if you care to be reckless with it, that is up to you, but you have no one to blame if something goes wrong. People CAN do this stuff if they follow guidelines, the question you must ask yourself is if you feel comfortable doing it. If you do feel comfortable, then do it but follow the rules and instructions to the letter. Dust is a disaster to computers and the only real way to prevent excess dust (which you will NEVER do unless in a clean room environment) is to keep your computer area constantly cleaned. NEVER... and I do mean NEVER get your vacuum cleaner anywhere near your computer. Your vacuum puts off static like crazy so, move your machine if you must in order to clean... and for obvious reasons (unless you have an ESD proof vacuum system) do NOT use your dustbuster or vacuum inside your computer... EVER. Get a surge suppressor. No, the $5 one at the Family Dollar store will not protect your computer. Nor will the $7 one at K-Mart. Expect to spend $20 on up for a good surge suppressor... Let's face it... this part is what is going to keep your machine safe or relatively safe from surges and brown-outs so if you skimp on it... blame yourself. Nothing will keep your computer totally safe, but most of these good suppressors have a guarantee that covers a certain amount of equipment dollars attached to it, so research BEFORE you buy. Messing with the registry is really tricky but some utilities are very nice and user friendly and will take the guesswork out of cleaning it up for you. Before you do ANYTHING with the registry... BACK IT UP! I have had more people tamper with the registry and then call me and tell me their machine doesn't work and they tell me they were messing with the registry. I ask if they backed it up before they tampered with it and almost all of them went, "Huh?" So, get a good registry cleaner and check if it backs up the registry before cleaning it. One last item... Invest in or begin good backup procedures. If your computer contains ANYTHING that you would be devastated if you lost then back it up. Look folks... shit happens and when it does, if the answer is that you MUST reformat your disk, you can wave bye bye to all those precious pictures, songs, school papers etc., unless you have regular backups made. Look this stuff up and find something that is right for you. Some are really easy, others are "geeks only" software so do a little fact finding before you purchase anything. OK... Off the soapbox. Edited to add a few things that, after reading what I posted made things a bit more clear.
