Windows 7: Random Computer Power Cutouts

Random Computer Power Cutouts

My computer randomly turns off. It doesn't shut down, but instead just turns off as if someone yanked the power cord out. I suspected an overheating CPU, so I cleaned out my heatsink, and I am running at a cool 50 degrees Celsius, but the problem still occurs. Also, I just upgraded to a new PSU, so i hope that is not the source of the problem.

An odd observation that I have made is that the power cutouts only happen when 1) i am actively using my computer , or 2) a background program such as "backup agent" is running. I can stream media from the PC for hours to my Xbox with no issues at all. Also, if the computer will be fine for days if I do not use it and none of those background utility programs run.

I was hoping that someone would be familiar with this situation and/or would have some troubleshooting tips. I don't want to go replacing parts until I know whats wrong.

Please let me know if any additional information will help, and thanks!

Hi and welcome to seven forums.

Sounds like something is killing it real quick, could certainly be a few things,guess you need to rule them out 1 by 1.

Do you have another PSU you could use temporarily to see if the new one is the culprit and faulty?

Shut down computer, remove all power sources, hold down power button
Why does shutting down the computer, removing the AC Adapter, removing the battery (if it is a laptop), and holding down the power button for 30 seconds fix problems in one's computer. I was recently corrected in a post of mine that this does not actually do anything unless one removes the 3 volt...

Computer wont power on after power loss
My computer wouldn't shut down, even with holding in the power button, and so I just let it run out the battery. Then it wont turn on. I tried holding down the power button to clear out any charge that might be remaining. I have managed to get it back on, but I have to make a connection at the...

Computer gets power, shuts off, gets power, repeats, never boots
When I got home from work tonight, my Win7 desktop appeared to be asleep, which is normal. I hit the power button to wake, it, walked away, and when I came back, it was not up as I'd have expected. I looked more closely and something really weird was happening. The fan would turn on and the...
