-Thanks for the prompt reply.
-Yes, I see the “Start Windows Normally” screen.
-I had tried both with and without the GUI opened when shut down or reboot but the result is the same.
-As you suggested to uninstall the ExpressCache software, the black screen is gone now when reboot.
-Questions:1)Would the 32gb SSD still work to speed up my PC without the installed software? 2)or you have other suggestions.
Many thx.
