I appreciate the help in advance folks. Ok, here's what I've got. Guy doesn't back his hard drive, and now I believe a power surge hosed the PS and mobo. Maybe some one can help me. When I replaced the ps, I get click, click, click off, on, off, on. The previous supply does nothing at all, at least this one lights the light in the front of the tower. My question is two fold, this emachines used a mini atx. I want to replace with a new mobo. I keep reading that I will need to reload windows xp. Ok, I'm fine with that, but I do have an extra HDD. Can I do a fresh load onto it, then get the data from the other by making it a slave even though it has xp loaded also. My plan is to move the data, save it (since the drive I have fresh is only 15 gig, and the drive in the computer is 40) to cd, then start fresh with the 40 that currently has what the guy wants. Is this all possible? The guys most important file is a huge data file of karaoke music for his buisness. Thanks is advance.
