Hey Tempers, My younger sister has been complaining about her computer shutting down during start-up of the system. She's running Windows XP Home Edition on an Intel Celeron 2.66GHz CPU, an ECS 661FX-M mobo, a SiS 661FX chipset, an 80GB IDE HDD, & I think (can't remember) 1.5 or 2GB DDR3 RAM. Its a really crappy machine but it worked before and that's all that matters because all she does is browse the web and sometimes does projects. Basically what happens is the computer boots up, gets through POST and the XP Logo begins to appear. About halfway through the XP logo, the computers shuts off abruptly. No error, no warning, just shuts off. I also tried an Ubuntu x86 10.04 Live CD and the computer shut off the same way before I could even choose to try Ubuntu as a Live CD. Luckily I have spare IDE hard drives, an "obtained" Windows XP disc, and a power supply on me. I'd suspect a faulty power supply seeing as its so old but I'd like the Temp's feedback first. Thanks a bunch.
