Question New Rig build: could post but unable to load Windows 10 flash drive also no signal to video monitor.

Nov 11, 2021
Hey guys how's it going? I was hoping someone can help me... I just recently built a new rig and I'll gladly share the specs with you! but my main issue is I get a post and everything was working fine but I have no video on the screen and in doing so I cannot load Windows 10 from a flash drive. I was able to go into the BIOS but I no longer able to do that! I've done a number of things, including reseating the ram and reseating the GPU, but still no progression. some other troubleshooting steps I took were reformatting my Windows 10 flash drive, by switching it from default FAT32 to NTFS, switching USB slots from front box to onboard mobo slot. any tips will be helpful!
Thanks Marco.
