How much you looking to spend on this little computer repair shin-dig? It sounds like you have an older computer, and I can certainly understand just keeping what you have alive. However, if you want to upgrade, I bought this for my parents with great results: http://www.newegg.com/Product/ComboBundleDetails.aspx?ItemList=Combo.390682 The above combo deal comes with motherboard, RAM, and processor. The processor is OEM in that combo though, so you'd need this too: http://www.newegg.com/Product/Product.aspx?Item=N82E16835106135 So thats $155 plus tax and shipping for a new dual core computer, not a bad deal at all. I just recycled their case, CDROM drive, hard drive, and power supply. Not sure if you could reuse your power supply without knowing what it was and what connectors it uses. The motherboard needs a 20+4, and an additional 4-pin connector Anyhow, it worked out great for them, they love it. Its blazingly faster than their old P4 computer. If that sounds like something you'd want to do I'll help you out with it. Making sure it'll all work together and actually putting it together. I have thermal grease, extra screws and cables that come in handy.
