New Bios driver messed up

Big trouble this time,

so i installed new bios software for my compaq laptop from the offical site (exidently i wanted to install new wireless network adapter drivers but i didn't read carefull enough) and now my laptop starts up i see the light burning and hear him running and everything but my screen isn't showing anything. From the biggining my screen stays black and i can't enter anything, i got a backup on a external harddrive and there is also a backup from compaq itself on a partition with vista on it. But i have no single clue on how to acces them with a black screen.

Please help me

If I understand correctly, when powering on the machine you are unable to view anything, not even access BIOS, is that correct?

If that's the case you may have bricked your laptop unfortunately
Either BIOS flash went bad, or you flashed with the wrong BIOS image

A Vista backup/recovery partition will most likely not help you...
You will need to send it to Compaq to be repaired (reflashed).

EDITED: hold on...you're saying you can hear Windows running? Perhaps the unit isn't bricked then...
Try booting in safe mode...

I had this problem with my old desktop. Unfortunately, my solution may not work, but what I did was give it a few hard kicks.

It actually worked. If you're willing to risk it, then you try it.

Otherwise, try reflashing the BIOS via USB (If you can). I've never done this before because my lappy uses software for that, but some can update through USB. Give it a shot.

That's bad. Flashing the BIOS is *always* a hair-raising affair, I hate doing it and it should ONLY be done when it's really necessary. That said...

You may have a paperweight on your hands. BUT, there's a couple of things you can try (others may be able to suggest more).

1 - Unlplug the AC from the system.
2 - Remove the battery from the motherboard.
3 - Walk away for 12 hours.
4 - Re-insert the batter.
5 - Plug in the AC and power it up.
6 - Keep fingers crossed.

On some boards, you can use a USB/Flash drive to boot with if you can install your BIOS Flash utility, you'll need a copy of the ROM, obviously.

Also, some boards allow you to unseat the eprom or simply replace a BIOS chip but I'm not familiar with your particular system.

If that doesn't work and your BIOS is shot, there may not be much you do, except replace the motherboard.

For the record, this is not a Windows 7 issue, whatsoever.

My laptop doesn't give power to the usb drive (neither the keyboard), however i can hear the cd-rom drive running and i see it's light flashing is there any thing i can do with that?

If the CD drive is spinning up, that's a good sign but it won't help since you need to tell the BIOS (which appears to be fried) which drive to boot from. And if the USB isn't being powered..?

Sorry dude, not good.

Start up the machine and keep pressing the F8 key and see if you can get anything that way, I know you said the keyboard wasn't responding but you never know it might be worth a shot.

Starting up with f8 wasn't helping and in about 1 hour my battery has been out for 12 hours.
