Right, I build my computer six months ago and every thing was working fine untill two days ago.

I got an asus sabertooth z77 motherboard and dicided to update the Bios.

I used the asus utility software. So I updated the bios and restarted the system.

And since that restart, it's giving me a black screen. All the components are making the right noises when turn the pc on, but nothing on display.

Here is a list of all the things I tried.

• took out my dedicated gpu and used the on board gpu. Did not work.

• flashing the mother board using USB. Did not work.

• cleared CMOS like 200 times. Did not work.

• Hold the del key during POST. Did not work.

Please.

Also, I just realised that the reason why it's not flashing the motherboard again, is it does not detect any external hardware. So, USB ports, keyboard, mouse etc are not working.
