Product: Pavilion 550-103na
Operating System: Microsoft Windows 10 (64-bit)
Pavillion Desktop 550-103na
On starting the black screen with the HP logo appears on the monitor and then the monitor goes into power saving mode. I have tried all the recommended resets and none seem to work.
The desktop will start in safe mode.

Since it starts in Safe mode, this means an app or driver that is being loaded as part of StartUP is the issue -- and that is a long and tedious process to diagnose.
You have to do the following:
1) In safe mode, do ctl-alt-del and select Task Manager
2) Select more details and select the startup tab
3) Disable all the tasks
If now, the PC boots OK, then is is definitely one of the startup items.
The process now is:
1) Go back to the startup tab
2) Re-enable the first task
3) save and reboot
4) If the PC boots OK, you have found the culprit -- if not, repeat steps 2 and 3 with the next task
5) When the PC fails to reboot properly, you have found the culprit

Thank you for your help in this.
I disabled all of the tasks in the start up tab and tried a reboot but got the same response as previously with the HP LOGO and the spinning wheel and then the monitor just goes to power saving.
Hopefully you have some other ideas.

I have done some further work analysing this fault and having exhausted all of the help for windows 10 and HP I was beginning to come to the conclusion that there was a problem with the graphics card. As a result I removed the AMD R5 card and rebooted. Low and behold the computer booted up. The resolution on the integral circuits doesn't seem too bad for my uses so I may just leave it out. I noticed the removed card had dust on the circuits that had not been rmoved by the vacuuming. So I removed the dust with a soft brush and some alcohol. On refitting the computer booted up but after a shortwhile it reverted to black screen presumeably as it heated up.
These graphic cards are largely unavailable so I cannot just purchase a new one.
