Question

Is it my power supply???

Jan 1, 2013 5:41AM PST

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,
Adam

Also, I did have someone check the temp and load test it.

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.

Roughly how old is the PC ?

Have you checked the system TEMPs ? If not download, install, run and minimize PCWizard 2012. All the relevant system temps will remain on the screen in the upper right hand corner. Write them down after bootup....then check/record the readings later.

Is the system free of dust inside the case ? PCs are like big dust magnets.

This seems to be an older PC, based on XP media center. Further, if you had this for a while it's just showing it's wear&tear. Other posters pretty much covered what needs to be done. If you plan to keep it then replace PSU that accepts it and maybe slighter better wattage. Further, while PC case is open, clean it out. Once PSU is replaced and PC is up and running, be sure *all* fans are running too, everywhere. If the problem returns, then you know the mtrbd. is likely a bad one that has succumbed to age. If you plan to keep it, consider the cost and or if it continues to shutdown if the PSU doesn't keep it up and other problem exists. You can slo checkout the infamous, "bad caps" problem, google for example and closely inspect your caps, they needn't outright super bad, just enough is all it takes. Oh yes, clean out the PC of dust bunnies.
