bios flashback Bios flashback on no display computer

[Iain399]

I have a m1h61r mb dell motherboard. Recently I reset the bios and now I need to flash the bios onto the motherboard. It does not display anything on screen but it did before. How do I flash the bios on a motherboard that doesn’t have a flash bios button? And that doesn’t display to a monitor.

resetting the BIOS doesn't wipe the BIOS, it clears the settings from CMOS is all, so back to default board options. You don't need to re-flash it.

If it's not displaying to the monitor that's a different problem. Could be many things, but some background info might help here, like what was the problem that made you reset the CMOS?  FULL system spec, and anything else that could be relevant.. the more info you give the easier it might be to tell you what the problem is.

Okay. It is an optiplex 3010, Core i5 3470, 4GB 1600mhz ram. No gpu. I reset the bios because there is a bios password I was trying to reset. @paddy-stone

OK, teeth pulling commence... only time I'm doing this.

 

Do you have two monitors? if so try the other monitor for seeing bios options etc. Does the machine stay on, or bootloop, or nothing at all?  what did you do EXACTLY to try and reset CMOS?

I have one monitor, it says no signal when I turn the pc on. I took out the cmos battery for 30 minutes then put it back. @paddy-stone
