Ok, a couple of months ago, my power supply burned up. Smoke and all, and computer shut down. I finally got around to purchasing a new power supply and installed it today. Now, when I turn on the computer, it shuts down after a few seconds, while booting up. Does it sound like something else was damaged due to the "frying" of my old PS? I have a 680i MB and 7950 GC. The new PS is a 680w. Should I take my PC to a repair shop and have them run a test on my system? Any insight would be great.
