My desktop computer is only turning on for a few seconds after that it turns off. I assumed it was the power supply so I bought another one. Last night I installed the power supply. It took awhile with me reseating everything and taking out the cmos battery to get the computer running. After that I used it for about an hour. I went home and came back to the office the next day. Unfortunately it reverted back to the behavior of only turning on for a few seconds after that it turns off. Can I please get some suggestions on what to do?
