Windows 7: BIOS update BSOD no display on boot.

BIOS update BSOD no display on boot.

After about 2hrs of searching, I was unable to find a post the worked for my particular problem.

Earlier I was trying to fix a DCP latency issue and latencymon suggested I update my BIOS. I got the BIOS from Asrock directly. During the update I was given a BSoD and memory dump. The dump froze at 15 and I eventually turned off the computer. Upon rebooting I was unable to get a display.


So far I have reset the cmos, switched between gpu and integrated graphics, removed the gpu and other adaptors, let the computer stay off for 30min; all of which has not worked. When resting the cmos I used both the jumper switch, quick clear, and battery removal.

Dr. Debug shows no errors when starting the computer and it appears to continue cycling boots, despite the lack of error. Any ideas as to what should happen next?

Motherboard - Asrock Z77 Extreme 4
Gpu - MSI 550ti
SSD - Corsair Neutron Gtx 128gb

Hi,

Do you recall the BSOD bugcheck/code? Are you able to enter the BIOS? Does it look OK/reads HDD correctly etc.?

It sounds as if you might have to perform a system repair:

Apologies, but I don't recall what the BSoD code was. I would run a repair if I was able to see anything, but there is absolutely no display. The monitors don't even react to the computer being on.

I can hear and see that the hdd and SSD are running and working, but without the display I'm unsure If either is actually posting

So, you can't actually enter the BIOS? Can you confirm this?
