My computer started blinking out a few times, and then quit and would not turn on. I decided it was the power supply, went to Best Buy and bought an off-the-shelf power supply and installed it. My computer is a Dell XPS 400 and originally had a 375W power supply, and I replaced it with a Dynex 400W power supply. I was able to get it to boot up to Windows (7) just once, although not on the first boot. Currently when I start the computer, I get past the splash screen, and then reach a black screen with the blinking underscore in the upper left corner of the screen. At one point, while the computer was sitting on, I heard a series of clicks, but it had no effect on the blank screen. Could a difference of 25W make a difference? I would think slightly more wattage wouldn't be a bad thing, but wonder now. Does anybody have any ideas? Your help is most appreciated!
