EDIT 1/16/09: Gave the reformat section a bit more clarity
EDIT 4/1/09: Rewrote Services entery
EDIT 4/2/09: Added startup enteries
THIS APPLIES TO:
- Mainly Windows XP
Some still applies to older or newer versions of windows
Hardware stuff goes with everything except a mac (i think)
WARNING
Please read the instructions carefully! While some of this is harmless, most of it can damage your computer if you delete too much (i speak from experience here). Probably the 3 most dangerous places on windows are the Registry, Your boot files, and msconfig. I"M NOT RESPONSIBLE FOR ANY DAMAGE DONE TO YOUR COMPUTER. I'm though willing to help to a point with any problems you have
Windows
1) Defragment your hard drive
Probably the simplest thing you could do. This speeds up the time it takes the computer to read data from the hard drive. If you wish to know more, Google how hard drives work. IMPORTANT: Do NOT exit out the defrager once you've started it! I have corrupted almost half the video's on my hard drive by exiting out early. Due to the length of time it takes anyway, this is something you would run before you left for the night. (this can be run from the command line too, try defrag -? for help)
2) Disk Check
Not really that important, it checks your disk for errors. Just run it every month or so. (NOTE: In windows XP the only easy way to get to it is though the command line. dskchk -?)
3) Virus Scan
Instead of trying to convince you what virus scanner is the best, that is up to you. Check sites like PCWorld.com, PC Magazine's website, and your techie person for what people think is the best. (me, AVG free, because its the best one that's free). The reason to scan?: Viruses, Spy ware, and Mal ware can seriously slow down your computer. If your on a slow computer, its even worse because spy ware can have resource hungry methods of spying on you.
4) CCleaner
This is a replacement of windows inadequate Disk Cleaner. Download it from here. Install and run.
A)Now, you should see a whole bunch of check boxes on the left-ish. DO NOT START RANDOMLY CHECKING EVERYTHING! Some of it you might want. If you don't know what it is, don't check it. And try not to check everything in the last group. That's basically most of your theme for your computer. When your done, click Run CCleaner, and yes to the prompt. (this will go ahead and delete the files)
b)Next is Registry Cleaning. NOTE: THIS CAN BECOME DANGEROUS. Keep everything checked and run the scanner. When its done, you'll be given a pop up to say yes or no to each key if you want it deleted or not. Since i am lazy i do clean all, knowing that if something important was deleted, i could recover it. For most people, that's what i recommend, because 1) you probably won't know what the key is and b) I've been doing that for a few years and nothing bad has happened. For you paranoids out there, you'll have to Google Windows XP registry structure to get more info on what is what, since i only have a general understanding.
5) Autoruns - Logon Entries
This is where it gets dangerous. Autoruns is a program made by Microsoft that gives you a much better view of your computer than any other program I've used. Download it here. It doesn't install anything. Open the program, it should start scanning. While its doing that, read this: UNCHECKING OR DELETING ENTRIES HERE CAN MAKE YOUR COMPUTER NOT BOOT!! A general rule of thumb is that you shouldn't uncheck anything made by Microsoft. What were concerned with is the logon tab. This is a list of all the programs that start when windows does (if your wondering whats with the discrepancy with the programs in the list and the total processes now, you'll see with System Explorer that one or 2 or the programs that start spawn many different processes). Some notes: If your anti-virus program (IE AVG) does not have real-time protection, then it doesn't need to start. The reason is that the only reason it starts is gather updates and wait for a scan (which you can usually initiate through workarounds), which wastes system resources. Just remember to turn it on once in a while, update it, and run scans.
For the rest of the stuff in there, it takes Google or risk. I used more risk than Google for this, you might only if you know what you are doing.
(EDIT)Here's a list of stuff i disabled after a recent reformat:
IgfxTray and Hkcmd: Used for quick access to graphics properties for intel based stuff. Takes up tray icon. Since i don't change my screen stuff very often, i'd rather goto graphics properties the long way then have an icon taking up space in my system tray.
Smax4pnp: Used for custom "effects and environments". No idea what it is. Since i only use basic windows sound, i'm disabling it.
CFTMon: Read this (yes, i know it says its for vista but xp instructions are there as well)
SunJavaUpdateSched: Checks for java updates, but is always running. I just made a bi-weekly schedualed task that ran it instead of every day.
Windows Search: With Windows Search 4, a new icon is in your system tray. Err, no thanks. If i want to search, i'll just click the search button in folders or goto start > search.
Startup enteries before: 13. After: 6. 3 Are needed windows stuff, avg anti-virus, comodo firewall, and system explorer
6) Services
(This part has been moved to viewtopic.php?p=252275#252275)
7) Use portable applications
A portable application is defined as a program that doesn't leave any files or registry entries. This helps with the junk that many programs put and leave on your computer. Try Portableapps.com, Portable Freeware Collection, and just prefixing your program with portable in Google.
8) Make a virtual os
This requires 2 things: a fast computer, and time to learn. A virtual OS is an OS inside of an OS. For example, you can run windows inside of a window on a mac and Linux in a window on Windows. The advantages of this is that when your Virtual OS gets a virus, becomes horribly slow, or other things, your main windows isn't affected. (Due to the resource strain Virtualizing something takes, playing games in your VOS isn't the best idea.
9) Complete System Reformat
This is by far the most time consuming and risky option here. But its the best one. Why? Because Windows tends to collect junk after a while. Your computer begins to deteriorate. Me being a semi-gamer, i've watched Halo 1's boot times get longer, and Rise Of Nations to become excessively laggy. A reformat would solve this. It returns it back to (even better than) the way it was as it rolled of the assembly line. Pristine, new. I've done this several times on my computers, and i can tell you, it works. Suddenly you find that lost power, and can give you that extra FPS to make the game smooth.
But this is not for the feint heated. You will need several tools: Your Windows Reinstalation Disk, Another large storage medium besides your main hard drive, DriverMax, and a print out of this guide. I'll try to guide you through as much as i can.
Step 1) Backup all documents and folders through out the entire hard drive (yes, even that secret folder) to another storage place. DO NOT BE LAZY AND MAKE A FULL BACKUP OF THE DRIVE, OR COPY THE ENTIRE DOCUMENTS AND SETTINGS FOLDER. Only copy what is necessarily.
Step 2) Download and install DriverMax. This program will update, then backup all the drivers you have on your computer. This saves you the headache of staring at a 800x600 screen, trying to get your network card working so you can download the drivers (this is from experience). Back to DriverMax. After installing it (and running the driver index), open up Drivermax AGENT (right click on the system tray icon and click Show Drivermax Agent Window), goto the Avalible updates tab, and see if it ran an update. If it did, open up each of the drivers and download the most recent one. After you've downloaded them, install them by double clicking on their names in the Agent Status tab. Once your done installing EVERYTHING, run Drivermax (not the Agent), and goto Driver Operations>Export Drivers. Now click Next, wait for it to index drivers, click Select All, click next, select an empty folder on your backup drive (you can use a zip archive if you have very limited backup space), click next, and wait for it to backup.
Step 3) Download all the installers (try portables first! Tip 7) for all the programs you NEED (remember, were trying to get rid of stuff we don't need). Also, download the IT VERSION of XP SP3 if your run XP. This will solve alot of problems with Windows Update.
Step 4) If your sure you've written down and backed up everything, now its time to bring out your XP reinstalation disk. First though, get into your bios (try mashing one of the function keys as soon as your computer turns on.) and set it to boot from the cd drive FIRST. If you don't see it, then you need to get a new bios if your on a really old computer, a very complicated process, Google flash bios for help; or your in the wrong place. Look around in your bios. Its there 99.9% of the time.
Step 5) (NOTE: In this section the exact keys and setup menu's might be slightly diffrent) Once you get the CD to boot first, you'll see something after you boot saying Press any key to boot from CD. Hit enter. Wait for windows to load the necessary drivers. When its done, press Enter to start installing Windows. Read the EULA, and press F8 to agree. Now you'l see a screen listing the drives which windows is installed. Unless you have 2 versions of windows, select your main one (Usually C:\Windows), and press Escape to install a Fresh copy of windows without Repairing. Now select the drive that has windows on it, press D to delete it, press Enter, hold your breath, and press C. When its done, select the right Drive and press enter to install windows. Choose between quick or full format (full does a better job, but takes a while), and press Enter. Once its done, i'll start installing Windows. Sit in front of your compy till it gets to Installing Windows in the progress area. Here you will get bombarded with prompts. Anwer through any of them. Wait till you go a while with out getting asked any questions before leaving.
Step 6) Once its done, your computer will restart. DO NOT BOOT FROM CD! Ignore it and wait till it goes to more configuration screens. Answer an questions. NOTE: One of the things is Activate Windows. I would recommend waiting until your sure your internet is working before activating windows. Another screen askes for internet configuration. If your on a WIRED network or hooked up directly to internet through ETHERNET, then select I connect to internet through My network etc. Unless you have fancy connection setups, just check Obtain IP Automatically and Obtain DNS Automatically. If your not on a network or hooked up to internet, just skip.
Step 7) Once your done configuring, welcome to your new Windows in your video cards native resolution! First, install Windows XP SP3 with that IT Version you downloaded. When its done, remember that DriverMax backup we made? Well, now lets use it. First, install DriverMax. Now, goto tools>import drivers. Find the file, select all the drivers, and start importing. When done, RESTART!

Hardware
Now i'm not all knowledgeable about hardware, but i know enough of the basics.
Essentially you can upgrade almost anything on your computer except motherboards.
To do this you need to be comfortable opening your computer, steady with a screwdriver, and a screwdriver. Before you start touching sensitive electronics, GROUND YOURSELF. Do not go into your computer after shuffling down a shag carpet.
These items are very fragile. Their not supposed to bend. Their not made to be rammed into their slot. A LIGHT push works on most things.
These items are very expensive to. If you shock your motherboard, you have to shell out over $200 for a copy of your motherboard. Handle gently.
This only applies to desktops. Laptops are very complex and isn't recommended for newbies
RAM
This is very easy to do. First, do you need ram? Ask yourself what are you doing that needs ram. Do you consistantly multitask so much you computer laggs horribly? For people that are wondering if they need ram, here are some general stats: 1 GB is ok for general use. Not that much. 2 GB is almost standard. 4 GB is quickly becoming the standard. Most likely you don't need 4 GB ram unless you do very resource hungry tasks at the same time. I'd recommend 2 GB for anyone that has intigrated graphics. That should give you good FPS in games. (NOTE: I have a P4 processor and 256MB ram and only when i multitask does my computer slow to a crawl.)
Now to upgrading, first, the ram is the long skinny sticks sticking out of your motherboard. Looks like this. They have tabs on the sides holding them in. Slide them out, then GENTLY pull STRAIGHT out. Look on there for the ram type (IE in that image its PC-3200U). Now, look at the slots you have and the size of your chips. You want to try to have 2 identical sticks for better management. I have 3 slots so if i had money i'd get 3 512MB ram chips. You might want 2 1GB + some random ram for your setup. Take into account money and slots. DON'T GET DDR3 RAM! Its not that good for the price.
To put ram in, slide it in STRAIGHT. DO NOT FORCE INTO SLOT. Once its in there correctly, slide the locking mechanisms on it. YOUR DONE
Graphics Card
This is where i get lost in the multiple types of cards, speeds, and ram. For me, unless your playing games and study FPS OR you don't have that much ram and multi-task alot. Having a GPU free's your system ram for important stuff. Its up to you
IDE DVD/HDD/Floppy Drive
Since i have only been consistently around IDE (ribbion cabble) based motherboards, thats what i'm focusing on. Unless you have a nice motherboard, you have 2 or 3 IDE connections on the motherboard. This splits out to 4 to 6 TOTAL connections. This includes HDD's, DVD drives, and Floppy Drives.
Upgrading any one of these things is pretty much the same. Open up your case, and CAREFULLY disconnect the cords. (IMPORTANT: DO NOT TRY TO TAKE OUT THE RIBBION CABLE BY THE CABLE! You will just tear the connection making that cable useless). Now try to find all the screws for the think your taking out (HDD's usually have their own covering. Take off the covering with the HDD in it, then take off the covering.) If it still doesn't come out, try opening up the front case. Usually (don't know about Le Fancy cases) its held in with tabs. Just squeeze where the tabs are and it'll come out. Screws should be revealed. Slide out. Take out any covering. To replace, do backwards.
Overclocking
THIS CAN RUIN YOUR CPU! -- Overclocking bumps up the GHZ of your processor, making it faster. But it also increases heat. Also, most CPU's are locked. Get into your bios and see if you can change it. If you can, google around for Overclocking X processor.

I can't think anymore. Hope i wrote everything clear enough.
