Hello i'm trying to get

if laptop, its very unlikely you could do this except by taking it to an authorized service dealer...
if desktop this is very easy. The motherboards manual will say the way to do it. Most often you must put a jumper on a certain location (check the manual) or less often you should take the small battery out, unplug from mails supply, shortcut the battery socket with a screwdriver etc. But as i said before, check the manual. If you dont have it, find it through the manufacturers web site - this is also a relatively easy task...

remove the bios battery or short it with the jumper ...and the bios password will disappear .....after that if this will not remove your log in password...just reinstall the operating system ...you will probably loose any data into the C partition if you choose to format it ...if you do not want to loose any data ..just reinstall the operating system without formatting the partition and choose to install in the same folder...

Hi, If you donot have have your bios password then the simplest way is to reset the bios to default. it will remove all the password form the bios.
The simplest way is to flash the bios is that open the pc cabinate.
look on to motherboard for bios cell , it is a kind of round circular battery like the cell used in watch.
take this cell out carefully from its socket. Now check there you see the two pins in that socket that connect that cell to the motherboard. Just short that point using any twiser or any thing . keep it short and switch on the powersupply of your pc. The system will not start but keep this pin short for 45 - 60 sec. and then switch of the power supple.put that cell in socket again. carefully.
now close your cabinate and start your computer. You see that there is no password on the bios now.
