Solved Set Bios back to defualt?

Specs: Windows 7, AMD
HP Pavilion Elite, Got around six months ago

So I had a problem getting my computer into Windows, but that isn't the problem. I heard online that you go into your bios and deselect the CD drive or something so I went into the bios and just changed all the settings in the advanced tab. For example I changed Video from PCI-XXX (Whatever it was) to Onboard and so on. I know it was a bad decision, but now when I go into my computer I turn it on and just get a blank screen. Is there anyway to set the Bios back to defualt?

Just to add, I notice you changed the video from PCI.XXX to On board. When you reset the CMOS memory it will probably default to on-board so you will have to temporary move the video out cable from the PCI output to the on board output.

That will give you a display where you can get back into the BIOS and reset all the other setting to there correct values.

Once you have done that, then you can think about fixing the Windows problem, but one thing is for sure, there is nothing, absolutely nothing in the BIOS that will fix a Windows problem. Once you have you display back, post again in the Windows 7 forum and somebody should be able to help you fix that problem

I,m sure pressing f8 wont reset your BIOS......to reset your BIOS to default setting you will need to remove the CMOS battery on your Motherboard ....remove plug from pc before u do this for obvious reasons, take out the Battery for at least 30secs then put it back properly and securely that will reset your BIOS. then just Boot as normal ok......please be careful messing with your BIOS it can cause your pc massive problems...ok...! ps look carefully on your Motherboard and look for CMOS printed on it, there you will see the small battery ok....!

Just to e pedantic. It is not the BIOS you are resetting, it is the CMOS memory. The BIOS is Read Only Memory and can only be reset by reinstalling the software, not something to be done lightly. CMOS is volatile memory where the setting set in the BIOS are stored. Because it is volatile it needs the battery to retain it settings when the computer is turned off.

While removing the battery will clear the CMOS memory there is usually a much simpler way. Most motherboards have a Clear CMOS jumper. This is a jumper with three pins . To clear the CMOS you momentarily move the jumper form one side to the other and back again with the power removed. With the jumper the effect is instantaneous. Removing the battery can leave the CMOS memory in an unknown state as it can take time for the memory to decay once the battery is removed,

I agree with one thing though, from the problem as described, pressing F8 on boot up and doing a repair isn't going do anything to solve the problem, might even make it worse if anything.
