Very Slow after updating to windows 10 after updating the AMD Video Card

[Nella1623]

I have an HP Pavilion dv6 Notebook PC Product No. A6N99EA#A2N Just updated to windows 10 which went very smooth. During the overall upgrade process I was prompted to update my video driver which I did. My Video Card: AMD RADEON HD6700M Current version is 15.201.1062.1151 Before the update no problems. After the update the pc is having long delays (BLACK SCREEN) at cold boot time and waking up after sleeping. Eventually it does boot and all is well after windows comes up. At boot time the windows 10 circle is rotating for a short time then I get a black screen for about 1.5 minutes then I see my mouse then a rotating circle again for maybe 10 seconds and then I get the windows 10 splash screen. All is fine after the splash screen. Same thing happens during wake up procedure.

All windows updates are current and I simply followed the download procedure when I was initially prompted to do the driver update. I have checked for updates several times from AMD but I always get the current driver is up to date message. These black screens are so long it is very unacceptable. HP support site is no help for they just point me to windows 10 and manufacturer of the device, card, whatever. I have uninstalled the entire update and reinstalled at least twice with exactly the same results.

The black screens make me think the system is waiting for a response from the video card and finally times out.  That's the way if feels. I have tried disabling the AMD services in the startup process but that didn't change a thing.

What can I do to stop getting the black screens and get back to a clean prompt boot?

Any help would be most welcome!!

This is how to fix the problem of slow boot-up with windows 10. This is mostly observed after upgrading from windows 7 or windows 8/8.1 to windows 10, it could also happen for various other reasons including system updates. Certain laptop models are also more prone to this problem than others. For instance, HP Pavilion DV6 has been reported to frequently have this problem after upgrading to windows 10.

The processes involved in this fix are as follows:

1. Open REGEDIT, Control-F then copy paste this EnableULPS configuration file to 0.

2. Turn off processes with high start-up impacts.

3. Disable the fast start-up utility function.

4. Enable the fast start-up again after restarting your computer.

Your computer should start a lot faster.
