It powers on but screen is black. I can use the USB and plug into my Windows 10 PC and it logs it as a storage device on the PC, but the ACER screen comes up on the Tablet, then sometimes I can get as far as searching for WiFi, but most of the time it just freezes on the Acer welcome screen, any help would be appreicated
