I7 laptop with SSD drive should boot in 10 to 20 seconds. After upgrade from win 7 to 10. The initial boot up to Win 10 logo is fast then screen goes black for roughly 2 to 3 Minutes. Thought it was the I place upgrade, so I did a clean install to have a perfectly clean system. This did NOT improve the boot time. (Once system is booted fully password entered it is fast and accurate.)

Forums indicate problem with laptops using dual Intel and AND video products. Tried following instructions to de install. Next, using native microsoft drivers for video, boot was FAST. Tried installing newest AMD SW and drivers returned the entire problem as it was before.

Clearly a problem between Intel chipset, microsoft win 10 and AMD. Seems many people have same problem and are reporting the fix does not work as it did not work on my computer.
