HI After about a week my new system just wouldn't boot, after running perfectly the night before. It was not even beeping on startup. I took it back to the shop I bought it from and the ascertained it was a dead motherboard! Now the new system has only ever been run through a new ups that I bought with the system. With reference to the load on the ups, I was running both of my systems through the ups (it has four outlets. ie 2 monitors and 2 computers).The second system is a 450 AMD. with 94 meg RAM, I was gaming on the old system (starcraft, ;not that heavy on resources) and windows trouble shooting on the new system. The shop requested the ups back for testing and have been unable to fault it, they are currently replacing the mainboard. I guess the question here is: why did it die? did I just get a dud, what other causes for a dead mobo except a power spike which the ups would have stopped?
