Hi,

I was trying to play a game that requires secure boot to be enabled. Weird thing is that secure boot was enabled in the BIOS menu but showed in msinfo32 as Secure Boot state off. I ended up going to my BIOS, turning secure boot off then on, and now my PC is not displaying anything. 
I’ve tried clearing the CMOS Battery by unplugging the power cable, removing the battery for 10 minutes and plugging it back in. Jumping the clear cmos pins, reseating my ram stick, removing and putting back the GPU. I also tried flashing the BIOS with a usb stick formatted fat32 with the 2.10.0.exe 

I’m not getting any display at all, just a black screen. 
The Alienware logo used to flash in a 2,1 pattern in white instead of amber. I jumped the pins and it no longer flashes but there’s still no display. To make sure there wasn’t anything wrong with the light, I took out the ram and powered on, it flashed 2,2 in amber. 
now there is no flashing, my wired keyboard lights up, but there still isn’t any display.
