I have the following: - Windows10 Home 1903 - 2 x 16GB G.Skill PC4 19200, 2400MHz - F4-2400C16S-16GRS - 1 x Crucial P1 1TB 3D NAND NVMe PCIe M.2 SSD - Laptop power supply - PowerTech 19VDC 80W max - Intel Wireless AC 9260 - vPro I believe that I have isolated the screen flashing to a driver or BIOS issue. The issue does not occur unless a game is running in full screen. I've been using Minecraft as the starting point. Windowed fullscreen works fine. Fullscreen creates issues where the screen goes blank for seconds at a time making the system unusable. The Intel wifi card is recognised, the BT component is recognised - the card is listed as disconnected. Similar to what would occur if a laptop had a switch to enable or disable the hardware. I have removed this for now to simplify troubleshooting. The main issue that is causing grief is that every time I reboot the machine I need to switch the BIOS restore default, repower, switch off the reset, repower again. If the reset sequence is not done then the system hangs at the UDOO Bolt boot screen - it does not progress. I have gone into the setup menu and reset the device to factory defaults and also optimised settings and the reboot sequence continues to halt at the same place. Any assistance in troubleshooting would be greatly appreciated.
