I have a computer that will boot (I think) but it requires an admin password to even allow it to boot.

THe screen is black and there is nothing on it but

Supervisor Password:

Is there anyway of changing this without knowing what the previous password is?

If not, what can I do to make this computer useable?

Yes, but it depends... How old is it? Desktop or laptop? "Brand name" or generic?

In most cases, you need to erase the contents of the battery-backed CMOS RAM. This is done by moving a jumper, usually the one closest to the coin-cell battery. For example, if it were a two-year-old generic desktop PC, and you could find the brand and model of the motherboard, you could go to the manufacturer's web site and download the manual (usually in PDF form). You could then find the exact location of said jumper from the manual.

If the unit is newer or a laptop it gets trickier. Some laptops and newer desktops use flash memory (semi-permanent, not battery-backed) and require a back door or special techniques to erase or reset the password. Since this varies from brand to brand, we would need to know more.

Like Tall said, you have to clear the CMOS. There's a jumper that's on the motherboard if you take the side panel off. Unless it's a laptop, then it's harder to do this.

You can Google for that specific motherboard once you take off the side panel to get a "map" of the motherboard so you can clear it.

Clearing it's easy though. Unplug power, put jumper on pins 2-3, press power buttons to fully discharge system, put jumper back on ping 1-2. Plug power back in, should have access.

There still should be 3 pins side-by-side with a jumper connecting two of them somewhere on the motherboard.

With the power cable unplugged, you can move it over. A small illustration:

1	 2	 3
  Jumper
 
1	 2	 3
	 Jumper

I know that's not pretty, but it gets the idea across.

After you do this, be sure to move the jumper back to the position it was in.

You can also pop the battery out for a few minutes. It's a little smaller than a quarter. Pop it back in and see what happens.

Sorry, this is back to antivirus things ... I downloaded the Grisoft program you suggested, ran it, and still get the svchost.exe error, which is what people were talking about further back.
What should I do???
