Years ago we had a machine like that. It was a stumper as we changed power supplies. Eventually the motherboard failed and a new motherboard cured the issue. Quite odd but understandable how ATX systems work.
I'd go for a bigger PSU first as its cheap. Then the motherboard.
Hi. Newb here. Need PC help.
I have a hp m7250n media center. It keeps shutting off at random times. The light stays on on the front while its shut down. The fan does not run on the power supply while this happens. The light on the back of the power supply turns off as well. I can only get it to turn back on if I toggle the voltage switch and plug and unplug the power cord. After I do this, the green light comes back on and it works until it does it again. The power supply is a hipro. That's all I know about it. Thanks for any help. The only think that has been done to the computer in the past yr is that we ha the hard drive replaced because it crashed. Thanks again,
Also, I did have someone check the temp and load test it.
