BIOS froze

[anglingPC]

BIOS froze when making changes so I had no alternative but to turn PC off, then it would not start and black screen.
Monitor hp w1907 I was troubleshooting it since it was giving me problems prior to this by going blank.

Welcome to Tom's Forum!

Most all MOBO's have a CMOS jumper, use the Jumper Clear CMOS procedure -> http://www.youtube.com/watch?v=rdHH9KrceR0

Thanks, but I did not have success with this. Tried on a good monitor, too and still black screen. No beeps from system. Doesn't look good.

Then it comes down to a failed component. To rule-out:

1. RAM boot with (1) stick; failure try another ; failure:
2. Remove the GPU and if possible use an iGPU (onboard video). You can also boot without a GPU and 'sense' (sound and looking at components) if the PC can boot. Otherwise try a different GPU ; failure:
3. Try a different and minimally sized PSU for your PC. Choices: (a) from another PC or (b) local store offering an open box or with a good/acceptable return policy ; failure:
4. Disconnect ALL peripherals including Mouse, Keyboard, HDD and DVD, and all USB devices and USB headers connected to the MOBO ; failure:

Now it get complex, the failure rates for MOBO 80% and CPU 20%. A local PC shop can diagnose the problem substituting parts to determine the failed component(s).

Were you flashing your BIOS with a new release, or just updating parameters within your existing BIOS?

 

[anglingPC]

I was editing the BIOS when it froze. Yes! updating parameters.

Thank You. I will troubleshoot for a failed component as you described.

I didn't mention that it is an integrated video. Which brings another question.
If I install a new video card since the integrated video may be dead, then how do
I access BIOS to change it to disable on board video to recognize new video card.

thanks for your help , still troubleshooting.

 

[clarkjd]

Most boards automatically disable the integrated video when you install the discrete video card. Just be sure that your monitor is attached to the card and NOT the motherboard.

 

[jaquith]

Obviously, connect your monitor to the GPU's video output ports, and in the BIOS look for PCIe Initialize -> PEG/PCI. If the MOBO itself is 'bad' then I doubt a discrete GPU will solve the issue. However, I sure 'hope' very much it does!!!

 

[anglingPC]

Thanks...I hope so too that new video card will work and mobo is fine. My concern is if it does work, then will it disable my onboard video so I can access BIOS.
It should disable from clarkjd's post. If the video card doesn't work at least I will know that mobo is bad, correct?

 

[anglingPC]

thanks for the info

Your BIOS 'may' have a setting 'Onboard Video -> Disable', but if it does not then look for 'Onboard Video Memory -> set to lowest MB value' and in the Device Manager look for Display Adapter [+] 'whatever your onboard VGA 'is' / right-click and Disable ** Warning don't accidentally Disable your 'NEW' GPU!!!

Let us know!
