HP OMEN not starting up or sending signal to monitors, keyboard, and mouse.

So I recently updated my graphics card drivers and when I went to restart my computer as recommended, my PC lit up like usual but I wasn't receiving a signal to any of my monitors, to my keyboard, or to my mouse. My monitors kept giving me a no signal prompt, my keyboard wasn't lighting up to indicate it was in use, and the red laser at the bottom of mouse isn't lighting up either which leads me to believe that the PC isn't responding to them. I've tried switching display cables, using different ports, and I've tried a lot of methods I had to research online. Before I restarted the PC I did accidentally install the drivers update twice but research online has told me that that shouldn't be an issue. I've also tried reslotting the CMOS battery, the RAM modules, and the SSD but at this point I'm not sure what else to try.

hi

Graphics driver update may have nothing to do with it.
If so, you should be able to at least boot, to browse the bios
booting into safe mode should also work
if not possible, your problem may be more serious than just a recalcitrant driver

exact model?
