z800 shuts down during windows startup

[knarfoetje]

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

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

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....

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
