I have a Dell SC420 server that I use as a regular desktop computer. Intermittently when I press the power button I get an orange blinking light, most of the time I can pull the power cable, wait a few hours, plug it back in and press the button again and sometimes I will get power. Sometimes if I change the power cord the computer will boot up right away. This problem didnt happen until we moved about six months ago. I mostly use the hibernate option when I leave my machine for extended periods of time, could this be the problem? Or are we looking more at the internal power source? Or could it be as simple as just getting a UPS for the computer since the power lines into my house are old. Thanks in advance for any help.
