A bit of a problem....

[Rickster]

So I felt like formatting my C drive today, i went into my UEFI Bios and i dragged the installation disk to the front of the boot queue, rebooted, and now the screen wont display anything and my keyboard wont light up. What could of happened?

PS: I did remove the mobo battery but its still the same.

Any related suggestions will be much appreciated, thank you.

Removing the battery on this board will NOT reset the BIOS. You need to locate the "CLR_CMOS" pins on the board. There should be a jumper over pins 1 & 2. You need to remove the battery, then move jumper to pins 2 & 3 for at least 10 seconds. Return jumper to original position(pins 1 & 2) - then replace battery & see if it boots.

No? So what powers the CMOS if not the battery?

On most PCs removing the battery & shorting out the battery + & - does the trick.

a mate had a similar problem, had him forward this address to me, there may be something in there to help you - in his case it was a dodgy power button.

Some boards store BIOS settings in non-volatile memory - the battery only powers the RTC(Real Time Clock).

Did you return the jumper to pins 1 & 2?

Yes, i even bridged PWR_SW and nada....

No beeps, LED's, nothing? Resetting CMOS will not cause that. I have a mate with an Asus P8Z68-M board & I have reset it twice so far...

Ok i got it to power on but, no signal to monitor or keyboard.No beeps (it never did,no mobo speaker) 1 Green LED on and i reset the Cmos with the battery in.

Like so

Good to hear it powers up. Have you tried connecting monitor to onboard video output? This may be the default output which you can change once you get access to BIOS.

Ill remove the gcard tomorrow (later) going to bed now, thanks so far.

No need to remove card, just remove monitor cable & connect to onboard gfx output. No problem, let us know how you get along tomorrow.

*Update*

I removed the GPU, still no signal from onboard GPU,USB and ps2 ports are dead. I think i may have bricked this board...

I would check voltages on power supply in the first place.

I dont understand why the PSU would be the problem, all i did was change the boot priority to a UEFI device (TBH, i dont know what that is)

The reason i wanted to format is because my PC was locking up even in safe mode, could this be related to the PSU?
