Hi all,
I think I solved it. My situation;
- Windows 7 profession 64-bit
- HP Probook with SSD
- After login screen a black screen with mouse cursor and no activity for 20+ seconds and after that normal desktop and everything was fine
This bugged me since I have an SSD for fast computing - not waiting. And I tried a lot of the things that were recommended such as:
- Booting in low-res mode
- Deleting and re-installing graphics drivers
- Creating a boot log, which did show several drivers did not load similar to this log
- Inspecting BIOS and considering switching from AHCI to IDE like some threads suggested but after seeing the warning that this might require re-installation quit the process.
The boot log didn't help much but one forum suggested viewing the event log (specifically system events) and inspecting it for any errors that might indicate where things went wrong.
In the event log I saw 5 consecutive warnings during boot, followed by 1 error - all in about the time the black screen appeard. The error stated:
"the hp cue devicediscovery service service hung on starting".
Through this hint I found this advice and after I switched the HP CUE service to "manual" - tadaaa! I have a speedy boot again and all still seems to work fine.
I hope this helps others too. And please also check the event viewer first to see if this is your probleem too, don't just switch off the HP CUE service but see for yourself what might be causing your black screen at startup!
