Made a big BIOS mistake.

**Maheriano** · 04-22-2009, 12:23 AM

I was optimizing my BIOS settings and removing things I don't even have like floppy drives. One of the options had my screen set as CRT+LCD so I changed it to LCD thinking there's no point in having the CRT there. When I reboot the machine now, it turns the screen on for 2-3 seconds and then the screen says POWER OFF and turns off. I turn it back on with the remote, it waits 2-3 seconds and powers off again. Any ideas at all how I can fix this?

EDIT - I do not have any other monitor, television nor any other type of screen at all except for a 42 inch LCD which is not mine and a projector which is bolted to the wall.

There are pins on your motherboard that, when shorted, will reset your BIOS. Look them up, short those pins, and start over.

Usually they are located for them selvs. (3 pins) but to be on the safest side... find the manual and look up FLASH BIOS

no no need to flash the bios.. just remove the small battery from the motherboard (or short the 2 pins next to it) one of these (or both) will reset the bios to default values

As everyone else has advised, You will just need to reset the bios on your mainboard.
There are two options here as both have been listed above.

The first is to move the jumper from the current pin setting to the other pin and wait upto 5 minutes then move the pin back.
Do not power on the computer while having the pins set to "Reset"

The second is to remove the flat battery from the mainboard and leave that out upto the 5 minutes. Once again do not power on the system while it is removed

Do not do either of these options while the computer is running and do not turn the computer on while either of this options is in progess

Do not get me wrong, I have many times powered on a system or done this while they have been running and never caused any damage * Noticeable damage*

Now that's some strange ways to flash the bios...

If you do it with the jumper... just power on, wait for the beep, and power off, replace jumper and power back on again... done in max 2 min.

Crinos, The above methods are not flashing the bios.

Flashing the bios involves running a boot floppy to reflash the chip on the mainboard..
generally you would flash the bios for a update.

The reseting the bios will reset all the settings back to default... Hence if the wrong video item is selected and you get no video.. This will reset it to the default it was supplied as.

And you do not want to power up with the jumper set to reset, This has been recorded to cause damage. By shorting the pins with the system of this will drain the memory on the board.

I assume you access the bios by pressing Suppr. or F2. but maybe your mobo can reload "optimize default" by pressing "Insert" just after post.

Or do a cmos reset.

Reset the CMOS with the jumper and all is well, thanks fellas! I also changed my 16:9 Xenarc 700TSV from 1024x768 to 800x600 for the first time.....EVER! Didn't really make a difference since the front end forces the resolution anyway but I like to think I optimized it. Back in business!
