In this Instructable, I will give a full documentation of how to disassemble a desktop PC, for parts. The specific computer that I will demonstrate with is an HP Media Center PC m7640n with a dead motherboard. Every computer is different, but this is a general guide.

If you don't fully grasp what I mean when I am describing something, please refer to the pictures!

Picture Quality Notice (and HD pics!):

Due to the amount of pictures I uploaded, they are of lowmedium quality. Click the "[i]" in the top left corner of a picture, then click "original file: (3072x2304) 1 MB" to see the high quality HD pictures!

Step 1: Unplugging

The first thing you do, is unplug every cable that's plugged in to your computer. That includes the following cables:

  • Power
  • USB
  • Firewire
  • Mouse
  • Keyboard
  • Internet
  • Ethernet
  • Modem
  • AM\FM Antenna
  • Cable TV
  • etc...
So pretty much just unplug every cable from your computer.
<p>no its not like that</p>
<p>wassup </p>
<p>LOL!Too bad my mother won't allow me to do this though...</p>
Here are some How to Guide on Computer <br><br>For more information visit.<br><br> www.baatkar.com<br> <br>thanks
<p>Thanks so much for your help! You really helped me make my science project at school; this took all my stress away. Thanks a million!</p><p>God bless you</p>
<p>Great job!! It helped me out considerably, I'm not terribly computer savvy but I do enjoy taking anything apart that I can to learn how it works. You said your mother board is fried, is that a Bios code or will the computer just not function? Also my computer is having a continuous beep, its done that before and I manage to push some cables back in and get it to work ,however not this time so I'm wondering if it's the motherboard or CPU..maybe someone can help? Thanks!!</p>
<p>Fantastic illustrations,I suggest that you may use arrows point at some features in the diagram</p>
<p>Very good instructional manual. Detailed step by step instructions. I love the Pictures. The only thing I can suggest is that you include a list of tools needed.</p>
<p>great instructions....my hp m7250n is loud and reboots without warning...would like to clean it well and rebuild it. It is 10 years old and I have already replaced the power supply a few years ago. (Could I; Would I; Should I) replace any components or add things to it before I rebuild it?</p><p>I noticed that the tv card will not pick up the new digital channels from my over the air antenna; it did when they were analog. Trying to cut the cable (Direct Tv) and use this computer for a DVR in the living room. Is this possible?</p><p>Thanks again for the instructions!!</p>
It would have been much wiser to buy a new mainboard and replace it...
Nah, I got a new <em>super computer</em>. 9GB of RAM! But, I used all of the parts from this computer, and hooked it up to another mainboard I have.<br/>
<p>i dont believe you</p>
<p>so how did that work out for ya?</p>
9GB of ram? Run cpuz and put the memory tab, take a screenshot and upload it here, I want to see proof...
It won't let me add a pic to the comment... I'll try again later...
upload it to www.willhostforfood.com and link to it.
If you want it that bad:<br/><br/><a href="http://www.instructables.com/files/orig/F71/QI3E/FVW22F2E/F71QI3EFVW22F2E.jpg">http://www.instructables.com/files/orig/F71/QI3E/FVW22F2E/F71QI3EFVW22F2E.jpg</a><br/>
You are aware that any more than 4 GB is invisible to windows...right? Well, I recommend that you dual boot XP and 7, And screw vista. With XP, you would get blazing speeds, in fact, you could turn off the pagefile to get even faster speeds, and with windows 7, i think that there are some features to deal with massive amounts of ram. What is your CPU speed? Take a screenshot of the First tab in CPUZ and upload it...
even better, TRI boot them like i did!!! P.S. I have a forum about this so check it out!!! PLZ
Tri boot them? I was planning on Tri booting Fedora, But my HDD is full now...
I was too, but fedora was stupid and wouldn't let me install it, but I could run it. A tip for clearing space, but try running ccleaner. It freed up 19 gigs if space on my drive. That's the only reason I'm tri booting not dual.
Yeah, Fedora and similar oses don't want to install to their own partition, they want to stay on the same partition XP is not XD I can't imagine how a program could clear 19GB of data, I Can count about 40GB of files that i need and are important, all of the files i have are taking up that space.
i don't know either, but it worked magic on my computer. just try it, and i bet you could clear up at least 2-3 gigs.
I'll try it, Where is it at?
I'd try ccleaner.com, but if you can't find it, I'll post a link.
I just tried it, it cleaned about 120MB of data -_- I simply need a new HDD...<sub>stupid tiny 80GB-er</sub><br/>
Yeah, I guess that my computer is pretty old... Some guy used it before me and filled it with a bunch of crap. I guess results may vary. ;)
So, where can I check this forum out??
If you can't find it under my profile, then do a search for something like " tri boot xp". It won't come up with anything at first so change the filter to forums. If you still can't find it, tell me and I'll send you a link.
Nevermind, here it is.
That's only in 32 bit versions, isn't it? The ram limit?
Yes, In 64 Bit Versions, Which are Unstable, The limit(i think) is 128TB
It runs Vista Ultimate with all of it's effects, smoother and faster than Windows 98, and it's even faster than many Linux distros!
CPUZ, Here is the direct download link.<br/><a rel="nofollow" href="http://www.cpuid.com/download/cpuz/cpuz_151.zip">http://www.cpuid.com/download/cpuz/cpuz_151.zip</a><br/>
And open the memory tab, The tab that is labled memory, and click it...
&quot;<em>this computer</em>&quot; as in the disassembled one.<br/>
Not my new one!
<p>thank you for your help. I really needed it.</p>
Thank you so much for such good info. My computer is shot so I want to remove any important info before I take it to recycling. It won't turn on so I can't use any &quot;wipe-out&quot; software. Thought I'd have to run it over with the lawn mower, but this method is much more civilized.
<p>i find that a sledgehammer is much more effective</p>
Haha! More civilized to the lawn mower.
<p>all u niggas is ugly as fuck</p>
<p>this is omar farooq the tuttie man</p>
HI-to all of you who have mastered the art of dismantling COMPUTERS, TV SETS, REFRIGATERS, WASHING MACINES, AIR CONDITIONERS, MOBILE BATTERIES. <br>you could save the universe from this E- WAST TIME BOMB which is is developing with so many of these products being dumped into the garbage specially more in the developing countries. in 15 years the lithium chloride &amp; other toxic compounds will leak &amp; enter the groundwater &amp; from there into the crops causing untold diseases of the kidneys ,INCURABLE CANCERS ETC. sometime back i had written a article that i wish to open a COMPUTER DISMANTLING SCHOOL IN PUNE CITY IN INDIA. but i am now 73 with all the ZEST in my life as a chemical engineer am willing to travel to any place for 2 months with a free stay where some expert can teach me the dismantling of the abovementioned items safely, which i will teach to my batch of 10 students at a time who after learning all this can set up their own business in a 30 ft x 50 ft tin shed wiith just 1 impact plastic impact crushing machine. <br>at a later stage we can call one enterprising tecnocrat from each of the 50 odd countries of africa plus 25 in south america &amp; which ever OTHER country there is a need. <br>our work will; be only upto the sage of dismantling, with the extraction of the precious metals given to the big companies doing this work. <br>THANKING YOU <br>balbir singh-mail- om.pune@yahoo.in
many thanks 4 the info, as i wish to set up a training school in india for COMPUTER, TV ETC RECYCLING where we will teach unemployed science students this work so they can set up small workshops(1-5 EMPLOYEES) on the city outskirts to take the parts apart &amp; sell the plastic, aluminium,copper &amp; melt the costly metals to be given to big recyclers. also removing the pvc from all electric other than from the computer wires by mechanical means.please let me know the size of the shredder in inches for the mother board. any info u can give on any aspect will be welcome as i am still in the learning stage. <br>many thanx &amp; awaiting your reply <br>balbir singh
Thanks for the tutorial. This just happens to be the same computer I needed to take apart.
I realize this guide was posted May, 2009. But thanks to author for showing how to remove the heatsink fan ONLY. Most online guides focus on removing fan, heatsink and processor. (Removing a heatsink on a Celeron D can cause processor pin damage and new thermal paste is needed if the heatsink shifts even slightly). And thermal paste ain't cheap. <br> <br>I nearly unlocked the two metal levers on the heatsink, thinking these are part of the fan locking mechanism. Due to Arbitor's guide, it's obvious fan screws just screw into the metal heatsink itself. In my case, I'm just cleaning heatsink fins for better heat dissipation.
