The gold reclamation process from computer parts (primarily cpus and connecting pins) involves the use of dangerously strong acids and should only be attempted by someone who has researched the process carefully. The 2 items which contain the most gold use similar processes with slightly different acids. I have tried this approach and found more effort in the process, required chemicals, and discarding of the waste products than the value of the gold I recovered.\nThere are a few sellers on EBay and other sites who will gladly sell you the information you need but rest assured that there is more money selling the process to individuals than thay make recovering.\nMay I suggest you sell your CPUs and "finger connectors" on EBay, (just use sheetmetal snips to cut the connector section from the board) they will fetch you a good price with a LOT less effort.

You could use the file transfer wizard, but I need more details like:  What operating system are you using?  Do you have a network set up at home?  Do you have a dvd burner?  If you provide any details from the following questions I asked, I could definitely help you out.  Nice work by the way, I saw the 360 page.  I like the golden toilet seat!  LOL

Sorry I don't have the link right now, but do a Google search for ccleaner (yes, two "c's"). That should do it for you, and it's a free program. Also, after running it, it's good to run defrag just to tie up loose ends.

I saw a very weird program on BBC America (or the discovery channel) where they made a furnace and put the ore in a cruicible with crushed glass.  After they melted every thing down, the impurities from the gold bonded with the crushed bits of glass, freein the gold from the ore.  You need a lot of heat and high temps, but no arsenic is required.\n\nAnother guy on the same program did the same thing by taking a carbon rod from a battery and hooking it up to 24VDC with two car batteries.  It heated it VERY quickly.  I am sorry I cannot remember the name of the program!!!!  It was using only 19th century technology to replicate settlers in Canada during the Yukon gold rush days.

Articles from the HTPAA Quarterly Publication - Tool Chest  \n\nFeatured Article on Rust Removal\nPart 1 - Electrolysis\nHome  \nElectrolytic Removal of Rust \n\nby Kevin Chamberlain, Member HTPAA ( published in Tool Chest #63, February 2002) \n\nIntroduction \n\nAt our last Tool Conference, there was a Panel Discussion dealing with the cleaning and restoration of old hand tools. This is a key concern for anyone interested in collecting old tools, since one rarely finds tools in mint condition in an original box. It is much more common to find tools showing the combined effects of correct usage, abuse, neglect and simple ageing. The primary question is: should cleaning and/or restoration be attempted at all?\n\nThe answers are conflicting; some aim to restore the tool to a brand-new appearance, eliminating all evidence of its life history. Others think any attempt at restoration will destroy the character and value of an antique tool. \n\nMost think some intervention is desirable to remedy the effects of abuse and neglect, while still retraining as much patina and character as possible. There is an important caveat - "when in doubt, do nothing". Cleaning and restoration of antique tools should be done in a careful and meditative mood - otherwise rash actions may cause loss of valuable information and/or further damage. \n\nRemoval of rust from old tools or other artefacts may or may not be a desirable goal. In some cases (museum specimens) stabilization to prevent further deterioration may be all that is necessary. Rust may be regarded as undesirable by tool users or collectors because it obscures identifying marks, causes seizure of moving parts, creates an unpleasant rough texture to the touch, stains the hands and/or the workpiece, or is simply unsightly. I believe rust removal is often justified, but the method chosen should not alter the surface in other ways and should result in a reasonably attractive surface appearance.\n\nThe electrolytic method of rust removal meets these aims very well and is also a gentle, cheap and adaptable method. Electrolysis is now being used by a wide range of artefact restorers, from tool collectors to marine archaeologists. \n\nIn this article, I mainly aim to outline the practical aspects of the electrolytic method so that members can try it for themselves. Several HTPAA members have been using the method for some years and find it very useful\n\nWhat is Rust? \nRust arises from the surface oxidation of iron or steel in the presence of atmospheric oxygen and moisture. As the rust forms, the surface of the iron is eaten away, sometimes evenly, but often deep local pitting occurs beneath wart-like protuberances. Rust occupies more volume than the iron it replaces, and so moving parts will tend to seize as they rust. \nChemically, most red rust is hydrous ferric oxide FeO(OH). If water enters this chemical structure, yellow-brown limonite may form FeO(OH).nH2O. Quite often, black iron oxides are also present usually magnetite (Fe3O4), an iron oxide which both conducts electricity and can be magnetised. The rusting process, and the conditions which promote, inhibit or stabilise it, are all important topics which are beyond the limits of the present article. \n\nMethods of Rust Removal\nRust usually binds strongly to the underlying iron or steel. Various methods have been used to remove rust. Mechanical methods include the use of emery paper, sandpaper or wire brushes (either manual or powered). More aggressive methods include sand blasting or shot blasting. Plastic bead blasting is a more recent and gentler variant. Clearly these methods will scratch the metal surface if the abrasives are harder than the metal. Wire brushes, for example, do not appear to scratch hard steel surfaces but they can be quite damaging to soft iron surfaces. \n\nGas flames are sometimes used to dislodge rust, relying on the different expansion rates of the oxides and the metal in response to heat.

Use a Cleaning program like CCLEANER .  This is my favorite program which only uses 1.31 MB of space and yet does a enormous job of cleaning all the junk out of your machine. Its also for free.

Since you no longer have a PC the least expensive way would be to take it to a shop and have them burn the files you need on CD's.  If you had or possibly have access to another PC the procedure is pretty straight forward.  Connect this drive as a slave drive.

they send thousands of tons of old PCs overseas and nothing is done with that material. if you want to get into something worth while get into aluminum. the price of that is real high right now.

check in dumpsters in buisness parks.  usually they just throw old computers and monitors away once they get new ones.

Quick clean would be the best in this case, because defrag will not of much effect in this specific case, and defrag takes a lot of time.

Why not just reformat it, and take it outside and beat it with a sledgehammer? (make sure to wear eye protection and gloves!)\n\nReformating it alone will not entirely remove the information! If someone still wanted to get to your info after that, it's possible, so reformat for good measure and physically destroy it on your own!\n\nEdit: You're not going to get anyone to help you if you're being rude to those who are already trying to - if you know so much already, why are you asking for help? We're trying to tell you how to do it completely without paying someone, which I think is better advice than shelling out cash for something you can do yourself.
