Troubleshooting unwanted shutdown.
This is an ongoing problem that comes up at startup. I hit the power button on the pc. It turns on, POST,boot up is fine, windows loads. Then just as the logon screen comes up the pc shuts down (well more like turns off!). Most times it doesn't make it that far. Sometimes it turns off at POST. It will even turn off after I log into windows. After it turns off it takes two or three tries to get it to boot up. At first I thought it was the Motherboard but Now I think it is the power supply. Does anyone have any ideas?
