F8 opens the safe mode. I think that on a Compaq it is F2 or F5 but Im not sure. Also you want to open the BIOS not the CMOS (compilmentry metal oxide semiconductor) they are all connected but that is the battery on the board that keeps a trickle charge going to the ROM CHIP which is what holds the BIOS settings. Basicly the CMOS is also what will clear and reset the BIOS there is usually jumper on the board next to it which you just switch from 1,2 jumper to 2,3 jumper it then shorts the 2 posts and resets. Also you can also just take the battery out for about 10 min and put it back in and then it resets the bios. This comes in handy if your computer wont boot sometimes from a corrupt program or driver. If you have the manual for the computer it should tell you what to press to get into the BIOS.

There should be a jumper somewhere on the motherboard that will reset the bios when you restart the computer.  You may have to download the manual for the motherboard to find it.  Make sure you set the jumper back to normal after you clear the bios password.

from the boot screen press your del or esc key to enter bios.  Then make you CDROM boot first.

Check the Fn key in your keybaord, as I remember it was Fn+F5, Fn+F6\n\nAny way\n\nIt could be disabled in bios software.

Make a bootable cd rom and see if it boots on that.\n\nYou can even try a non-Windows OS (gasp!)\n\nLastly you could try to flash the Bios

Yes, just go to your computer manufacturer's website and they'll have the latest bios for you to download for free.

You mean everything? BIOS just woldn't come up? There is no way to fix that unless you send it in to the maker of the BIOS or where you bought your ocmptuer so they can fiz it.

The easiest way  is to enter BIOS. this is usually done by hitting the F1, F2, ESC or DEL key (some laptops even require a combination of keys such as CTRL F1) If you can't do this, for example you've messed up your settings so bad that it doesn't start anymore you will have to remove the battery(CMOS battery). If you choose to do so remember to not only unplug thue power cord but also remove the laptop's own power supply the battery(not the CMOS one). Once you've located the CMOS battery remove it and wait a while. Then plug everything back in and boot. \n\nPS if you don't have experience with hardware and laptop hardware in particular don't try opening it in your own

You can't. The BIOS is what tells the computer how to handle devices.\n\nIt's kind of like trying to train your brain to use the third arm you want to add.\n\nYou could put in a CD drive and look up "Bart's PEBuilder". It's a way to boot to Win XP from CD. Full GUI and all with the additional data provided by "Sherpya".

It usually depends on the manufacturer of the motherboard.  If the machine is bought from a brand name such as Dell, HP, Compaq, etc... you'll probably have to go to their respective website and look up something like support or downloads.\n\nHowever, if it is a homebuilt machine then you'll need to open the machine a determine the manufacturer of the motherboard as well as the model number.  After that then you go to the manufacturer's website and try to find BIOS updates that you can download.\n\nLast thought on BIOS updates though, be very certain that you are downloading and installing the correct BIOS, otherwise you can render your PC inoperable.

If yours doesn't, just do it very, very slowly and methodically, remembering the order you take bits off.  Some connections are very delicate, too.. my husband recently took apart an old thinkpad and snapped the little plastic bit which joined the keyboard on, if we hadn't had a spare thinkpad for parts it would have meant curtains.  Usually RAM is very accessible, though.
