Solved!

z800 shuts down during windows startup

HP Recommended
z800
Microsoft Windows 10 (64-bit)

Hello,

I have a z800. It was unexpectedly powered down when I got back from Holiday.

After turning it on it shuts down itself a few times during Windows startup.

Later I saw it doing a windows update. (win10).  I don't know if this is finished correctly.

When I go to the bios the computer stays up and running. So I guess it's not a power supply issue.

It keeps shutting down during windows startup.

Is that expected with the latest update and an old computer?

tnx

frank

Thanks guys,

Just as a test I replaced the psu and the machine is still up and running.

It looks like the energy demand is higher when the windows startsup/runs then when just in Bios.

Never seen this....

No, that is not expected.

 

On another computer, can you Download Windows 10 (microsoft.com)

and write the "installer" to one DVD-writable media, or to an 8 GB (or larger) USB memory-stick?

Then, boot your computer from this "installer", and choose "repair", instead of "install".

it's not rocket science,..................... your post STRONGLY indicates a corrupted OS or a misbehaving application

 

the one cure that is most likely to fix this is a OS reinstall followed by a application reinstall following a one by one app install procedure

you can do a "BIST" test on both supplies by removing all power connectors from the supply then connect it to mains  power, if green light glows, and fan spins supply passes self test
