Tony, they guys hit it on the head. Check the connection first then try a different monitor if you can. If you recently disconected the monitor check and make sure you didnt bend any of the pins in the connector as well, they bend easily.
me, in some cases you can buy just the computer and not have to package it with a monitor. It all depends on what you are looking for and what you want to spend. The options are really endless. You will just have to do some shopping and find what you want. They really build these machines to be disposable these days thats why they are so cheap. Wahtever you get just make sure it has some ram memory in it. Most come with 256 meg of ram, get it upgraded to 512, ram is cheap and windows xp will run much better with the extra ram. As far as moving the data theres ways to do it. If you have something like a zip drive you can just copy it there and more it or you coult take the hard drive out of the old pc and put it in the new one and copy it. you could also put network cards in both machines and setup a home network and copy it over. The zip drive is the easiest option by far. If you have any questions let me know, im more then happy to help.
