PC restarts after turning on

[Spikey33]

Hi,

This problem has started in the last couple of weeks. Every morning when I turn on my PC, within 20 minutes it reboots. That's it for the day, it doesn't do it again. Suddenly the screen will go black for a few seconds, the power stays on and th HP logo appears and proceeds as if I had just turned it on. Any ideas? As it's driving me mad, as it always happens when I am in the middle of something! Thanks.

The default setting when a PC crashes is to immediately reboot --which makes it impossible to see any kind of diagnostics messages or screen.

Here is a thread explaining how to disable that function:  (9) Enable or Disable BSOD Automatic Restart in Windows 10 | Tutorials (tenforums.com)

Hope this helps

Hi,

Thanks. Although I tried this a few days ago and has not made a difference. Also meant to mention there are no error messages or blue screen! Thank again

Regards,

Mark.

If the PC is suddenly simply turning off, and there are no messages or BSODs, that is generally either a failing drive (which hangs when trying to read a bad sector) or overheating.  The second is more common in laptops and rare in desktops, so I would not suspect that is the case.

To determine the cause with hardware failures, you have to be able run diagnostics. We have no way of accessing your PC from here, so we can not do that for you. You have to do it yourself.

You do this by pressing the Esc key repeatedly when rebooting and then, when the HP Startup Menu appears, selecting Diagnostics (usually F2) and letting it run.

If it is NOT possible to run diagnostics, or if that does not work, then there is NOTHING more you can do by yourself -- and there is NOTHING we can do because we have no way of accessing your PC from here to run diagnostics or repair hardware.

You will need to have the PC physically examined in a service facility by folks that can run their own diagnostics to determine what is wrong with it.

Hi,

It doesn't turn off, the screen goes black (power never goes off), for a few seconds, then the HP logo appears and it boots as normal. It then works perfectly well all day untill I shut it down. I will try the diagnostics.
