Does the VisionTek card have its own drivers? Try booting after installing the card (and drivers) with Secure Boot enabled. If it won't boot, disable Secure Boot and try again...
I previously asked will the VisionTek 2 Port USB 3.0 PCIe SFF Internal Card - 900598 work in the Dell Inspiron 3670, and got the answer. My new question pertains to the Secure Boot. I had asked about installing a non-Dell video card which I got the answer that I must turn the Secure Boot function off in the BIOS. I purchased a Dell video card so I did not perform this function. This question pertains to this VisionTek card. To work, will the Secure Boot function need to be disabled?
