My CPU started to smell like burning after I was trying to convert a divx file to DVD format. My CPU is 800MHZ 512MB RAM and 8-9 years old and I finially think I cooked my processor. I've done alot to keep it updated over the years-new powersource, USB 2.0 port, internal DVD burner, and upgraded RAM. I'd like to try and build my own tower, but I'm clueless on where to start. what parts would I need to build a tower that can encode different video formats ex: divx to DVD, download, burn, listen to music, watch my college webcast class and play poker all at once? I dont understand processing speed capabilities or how much RAM it would take? I dont use it for games(Keep that to 360/PS2) so I think I can recycle my tube monitor, speakers are good enough, A wireless keyboard would be nice so I could hook it up to my 100" projector and run HD-DVDs or Blue-Ray files from my CPU, if thats even possible??? Thanks for any advice. Keep in mind my budget is a 27 year old married math teacher. This would be real nice too: Entertainment System/Media Center Computer This is a computer designed to sit in the living room with the rest of your A/V gear. The idea is that it will record and serve audio and video files for replay via your existing television and stereo. The current notion is that this computer should be built in a special case that makes it look more like a stereo component, the size of which can present a challenge when it comes to getting all the necessary parts fitted. For this system a mid-range processor will be fine, along with a generous amount of RAM. A fast Ethernet connection will facilitate sharing large files. You’ll also want a TV tuner card (or two) to get video in and out of the machine. Many of these also provide DVR functionality, often without the monthly subscription fees and DRM restrictions required by companies like Tivo. A wireless keyboard and mouse provide for couch-based use and a separate monitor may be unnecessary as your TV will fill that role. All components should as quiet as possible since you’ll be watching/listening in the same room. For this application it makes sense to trade a little power for passively cooled parts.
