Video Computer Died

Well today we had to go out and run some errands. While we were out I thought I would download the video for our TV broadcast on to the computer we use for our editing. I started it up, and off we went. When we arrived back, the computer screen was blank and the computer was making a weird noise. I turned it off and back on again, and the same thing happened. So I opened it up and the problem became very apparent, the cpu cooling fan had stopped so the Athlon XP 2100 processor is now toast (sort of literally.) It is totally burned out. That means at the moment we don't have a video editing computer, which is a problem since we have a broadcast coming up this Sunday. After some thinking, I decided to take out the hard drive that has the raw video on it and put it on another much slower computer on our home network. That would allow me to copy the video file (if it was downloaded before the computer died) to my laptop (the only other fast computer we have which has a DVD writer) and do my editing on it. I did that, and after some trouble found that the video file was there. Now to copy a 16 Gigabyte file over a network connection. This is not a fast process. It will work for now, but I think I need to find a way to get my video computer back up and running. I figure since AMD has stopped making the Athlon XP processors a long time back, to do so will probably require purchasing a new motherboard, processor and ram (my current machine used SDRAM not the DDR ram that most current motherboards use.) Best case situation is probably about $200 before taxes. If editing works well on the laptop I could go a much less expensive route and purchase a firewire card for it. That would allow me to do all my editing on the laptop from taking the digital video off the tape to writing it back to DVD or videotape. Cost wise, the second option is much preferable. I guess I have some decisions to make.
