[SOLVED] Windows 10 wakes up from sleep but black screens

[vanboom]

Dell T3500 upgraded from W7 to W10: computer wakes from sleep mode after moving mouse or pressing keyboard, but screens stays black. Have to power down computer and restart. Latest Bios, latest drivers for AMD Radeon HD6700, NVIDIA Quadro 2000. Short of fresh reinstall of W10 what can I do?

By upgrade, did you use the internal upgrade path? If so and you haven't performed a clean install of the OS after said upgrade, then yes you will need to reinstall the OS.

If you, performed a clean install of the OS as a migration away from Windows 7, then check and see which version of the OS you're currently on. Why would you have two different GPU's on your system? You should be working with the single most powerful card on your platform.
