Unplug your desktop from mains power.
Open the case.
Locate the 3 pin CMOS password reset jumper on the system board. It has to be near the small bios battery that looks like this

Remove the jumper plug from pins 1 and 2.
Place the jumper plug on pins 2 and 3 and wait approximately 5 seconds.
Replace the jumper plug on pins 1 and 2.
Power up the system and check the results.

    This is the suggested solution from Dell for the OptiPlex series. Are you sure about the model, because there are variations between Dell models.

    Waiting clarification, don't hesitate to post.

even though I am ARMY... I'll give it a try. :D
you will need to open up the laptop (video embedded) and remove the watch battery to reset the BIOS password. I would suggest leaving the battery out for a few hours as there are capacitors installed to keep memeory going incase of battery failure. but capacitors dont last forever.

I had problems with my monitor. I am purchasing a new monitor. When the new monitor is connected to the computer does the BIOS default setting adjust to the new monitor? I am just a computer user not,...

Sometimes the BIOS doesn't display properly on the widescreen monitors if your video card was built before widescreen monitors were acceptable. I have an old ATI Radeon video card from 2006 and it cuts off the BIOS setup screen when setup. If a 640 X 480 monitor was plugged it, the problem would go away. The graphic drivers aren't going to initialize in your computer until the computer is booted which compensate for the current resolution settings.

Another solution is to see if you have a BIOS upgrade available for your computer that will create a resolution and refresh rate that will work for your monitor.

How do I get rid of the soyo dragon off my computer. It is the first thing I see after I turn on my computer

You can turn this off in your Bios settings.
To do this, press delete when computer starts booting up and this will open the bios screens.
Go to Advanced Bios Features and look for 'Full Screen Logo Show', set this to disabled.
Some of the soyo boards will vary in how you do this so just look at what yours has in the Advanced Bios page, some you will change the Logo size to make it go away and another you switch between Logo-0 and Logo-1.
Lastly, if you are running the p4i865pe plus dragon 2 v1.0 board and/or bio version 865dp1a2 there seems to be no way to get rid of it (updating that bio version to the newest one may change that though)

Hope this helps you resolve the issue!

BIOS ROM Checksum Error - no POST, no beeps, no display -HELP!

If your computer turns on and no display then you have faulty memory cards, replace them with new ones and make sure you use the right kind. Bios settings are usually set to default and factory settings, you should not have to update them. Usually if you hear no beeps when you turn on the computer, then your memory cards are faulty. I hope this helps.

My computer won't start up right

press F1, when it boots you are going to have to go down to the date and time, and click on it then you will need to put in the correct day date and time. If pressing f2 it will take you into the bios, and you can set it from there prior to booting, unless you know what you are doing, stay away from the bios, it can really screw up your computer. Good luck and Peace,Gym

Xbox error 06

if it has the stock bios imma guess you locked the hard disk drive with the old hard disk key. and if you did that its going to give a error code six. error code six means the xbox cannot unlock the hard disk. either reflash your bios or install your old hdd back in, get the eeprom info, find a tool by teamassembly "cant remember what its called but it takes your eeprom and creates a custom key for that specific hard disk drive" i dont use that **** anymore tho because i have my **** flashed with a bios that isnt so anal about locked hard disk drives, but you may need to go back to the old hdd first and reflash it with a different bios instead of doing the hdd lock code ********. if u want my opinion on a good bios go for ind bios 5003. try xbins

Can't boot bios

This is common after doing a BIOS upgrade. It usually means that the bios was successful, but that the motherboard is just now recognizing that it has a new bios. In other words, it's seeing that the new bios is not the same as the old one you had before, and is giving you a warning that it's changed. You can usually go into the bios, and clear all messages. This should make it go away. 
Post your specific motherboard, and i'll see if I can get you more info.
