Why does my computer shut down on it's own

Hewlett-packard / PAVILION

Specs: Windows 7, Intel Pentium D 925
This a revival of another post that was closed due to inactivity. I am sure the computer is off (no signal light), I have set the hard drive to never shut down, I have checked for cleanliness in the desk top (it was quite good, but did blow out a little dust), Windows checks for "why the computer had shut down", but still have the problem.

Would be nice if there was a real solution that Windows could ID. I'm hoping one of you might have another idea as to what I might check. Thanks a bunch, Uncle Dewey

Check your CPU temperature. If you have a Pentium D 925, it's a hot running CPU with a fairly low max temp of approx 63C, so it's very important that the thermal paste & heatsink are installed correctly. If the CPU temp goes too high, the system will automatically shutdown to protect the CPU from frying.

Spontaneous shutdowns are usually due to to hardware issues. Often this will be overheating or a weak or failing PSU. OEM computers are not known for having good PSUs.

Windows can't tell you much about hardware problems.

Did you clean the CPU heatsink, with care it can be done through the fan blades with a small brush and some canned air. As given already, getting temperature readings is really the first step.

Always pop back and let us know the outcome - thanks

I did not get behind the heatsink--I can try to look in there with a flashlight. Also, I'm not sure how to place a thermometer properly, or the what is the right kind of thermometer use. It may be awhile before I can respond--my doctors need more income. {;-)))) {:-(((

I now have more info, and thanks a mil, Uncle Dewey

Try this small app: https://www.techpowerup.com/realtemp/

It shows temps of your CPU and individual cores and possible GPU.

You use a program to get the temperatures off the existing sensors. Here's a freebie:

I have downloaded the program that Derek suggested. However, there are no instructions as to what to look for, or what action I might take to balance/correct temperatures.

Tx a bunch, Uncle Dewey

Look at the little thermometer symbols, particularly the CPU and any high ones. Better still take screen captures and put them on this freebie website (no account needed):

Just paste the addresses (URLs) they give you onto this thread. We can then have a look at them and let you know what we make of them.

Hi Derek,

I think the document is: http://www4.zippyshare.com/v/oigdtE... I had to capture the screen three times and paste them in to MS Word.

The temperatures are on the second part, showing around 31C. Nothing to worry about there. [Just for info, any problem with temperatures would have been a hardware issue which the program could not have corrected].

Can't add much more to what was already given in #2. A faulty PSU is likely but it is hard to prove without substitution.

I agree, since the temps are good, it is probably a bad power supply.

You have to be a little bit crazy to keep you from going insane.

Thanks a bunch for your analysis. Even though it looks good, I will eventually visually check the PS.

If I ever find a solution, I'll let you know. "Preciate it" Uncle Dewey

Yes, please do that. Thx.
