Got a HP from a friend, wouldent get past the xp pro screen so I went into the bios and under OS it had windows 98 something else and "other". So like a dumb....I clicked "other" and saved.
It starts, fans, lights but only goes to the HP screen and won't let me back into the bios to change it back.
Please help me get back into this computer.
 
alright, i had the same problem once, on the mobo there is a three prong thing(lol) that says clr cmos, and on those three prongs is a little adapter that covers two of them, take that and cover the middle and the one that hasnt been covered yet and then start the comp, once you start the comp, turn it off and put the adapter back and the bios is back.

thats at least how it had to happen on my foxconn mobo
 
What you have apparently done is change the settings stored on the CMOS...this is accessed through the BIOS.

You need to "erase" the CMOS and that will allow you to get back into BIOS and enter new CMOS settings.

Two ways to erase the CMOS:

1. Remove the battery on the mother board for a few seconds. (Computer turned off of course!) The battery is what saves the settings on the CMOS...no battery, no power, settings are all lost.

2. As the post above says, there are usually two little bare metal prongs sticking out from the mother board. On the board these prongs may be labeled as "CL CMOS". Use a metal object like a screw driver to short out the prongs for a few seconds. What you are doing is shorting out the battery and denying power to the CMOS.

Once the CMOS is cleared, you should be able to again access your BIOS.
 
do what the first poster, joelmager, said, not what samuel said

To find out where on your mobo the prongs are look on the board and you should see some letters+numbers, faily large. It is usually under the manufacturer name.

So for example, mine says Asus, then underneath that P5N-E SLI

Google the motherboard, so i would google Asus P5N-E SLI, and click on the manufacturer website, chances are there will be a link to their motherboard somewhere on their site

There should be somewhere on there to download the manual. If you cant find it google <motherboard manufacturer and model number> manual

The first page is usually the motherbaord layout, showing nb, sb, cpu, ram slots etc etc, including the pins and what they say. look for the one that is cmos clr, clr cmos, whatever it is, it is obvious, it is along those lines.

Wherever it is on the manual is where it is on your motherboard, so go back to your computer and look in the area that it says it is in in the manual, then just do what was said on the first reply
 
Aastii...thanks for your reply to my post! :)

I am very curious, what is it in my post that you think is so wrong that my post should be disregarded?? :confused:

I've only been working on computers for a few years and still willing to learn!
 
On the picture of your mother board, item #18 is the CMOS battery.

It looks easily accessable. All you need to do is take the battery out of its holder for a few seconds. That will cut power to the CMOS and it will be erased. Put the battery back in, boot up, and you should then have access to your BIOS and from there you will have to do your CMOS setting anew.

(And, I'm sure you know this, but be sure you have no static charge on yourself while poking around inside the case. You don't want to permanently erase the CMOS! Simple way to do it is just be sure to touch the computer's metal case before you touch anything on the mother board.)

I took the battery out last night for a couple hours and there was no change. I tried pressing f12 and every other button several times while turning on the computer.
I have now had the battery out over night, a article I read said it can sometimes take along time, I am gonna plug it back in later and will let you know.
 
the problem i had was the fiddlyness of it all. the screwdriver thing can easily knock something on the mobo and break it or, with a little slip, bend the pins. It is easier to use the traditional method of moving the jumpers off, starting up, shutting down, putting jumpers back and then starting as normal. I just don't feel that a full hands on using tool and all sorts is the best way as there are more risks.

As for the battery it has been known before, uncommon, but still a risk, that bioses have been erased or corrupted by cutting the power completely. It is uncommon but still a risk.

With that being said though from the page you poseted with your mobo picture and stuff i cant see the jumper so the battery method may be the only way.

get a rigid piece of plastic or a flat-head screwdriver or something similar and push the hinge on the battery away. lift the battery out, wait 10-20 secs and then replace. see if it has worked.
 
i have just read the post that you litteraly JUST posted whilei was typeing, ill check back later and see the results and work it out further ^^
 
no dice
The battery has been out for almost 24. I put it in, plugged it all back up and nothing. The fans are running, the keyboard lights flash the first second of turning it on but then all stay off. the moniter has nothing but a blue screen with the HP invent logo on it. It won't power down without holding the button in. I put a floppy of XP I used years ago for a differant computer hoping it would try to install some kind of operating system.
If I clicked "other" under OS in the bios I thought it might be waiting for me to tell it what "Other" OS I'm referring to. I never changed the boot sequence so how will it boot from either disc or floppy?
A coworker just lent me this, I hope I havent made to big of a booboo, your help is appreciated!!!
