How do I reset a BIOS password ?

There are a couple of ways to try and reset the password. The first thing you can try is to remove the CMOS battery and leave it out for about 20 min and then put it back in. This will clear all the settings and should clear the password too. You will most likely have to reset the system time etc in the BIOS.

Another option is to see if there is a generic password for your brand of computer that you can use to get into the settings and clear the password. Many companies use a standard password just in case something like this happens.

If you can find the motherboard manual then there might be a jumper you can short to clear the BIOS password.

I'm getting a blue screen error that says - irql_driver_equal or less

Automatic reboots can be caused by several different things and are hard to diagnose. One thing you can try is turn off the automatic reboot option under the recovery options for your computer. This will make it so your computer won’t reboot on errors so you can see any problems. Go to to System in Control Panel and go to Advanced System Settings. Then click on the Advanced tab and then the Startup and Recovery Settings button and uncheck the box that says Automatically restart. The next time you reboot, it should stop on the Blue Screen so you can read what it says.

The next thing to look at is to see if you have installed any new software or drivers or even any new hardware on your system. Faulty drivers can cause reboots as well. If so you may want to uninstall the software or remove the new hardware and see what happens.

There can possibly be a problem with your motherboard's< a href="/support-categories/hardware/487-what-is-the-bios" target="blank">BIOS. You may want to do a BIOS update if there is one available. Just be really careful to do it correctly because you can ruin your motherboard if you don't.

I get an error message saying "Invalid configuration information. Please run setup program. Strike F1 continue or F2 to run setup. Portable device2.dll was not found."

It sounds as though your motherboard CMOS battery is dying. When you are prompted to go into setup at boot up it usually means there is a configuration problem. One thing you can try is to go into setup and check the date and time in the BIOS and change it if it's wrong. Then save and exit and see if that solves your problem.

Once you fix the configuration problem in the BIOS then that message should go away. If your time continues to be off then you should change the CMOS battery. They are only a couple of dollars and you can get them at an electronics store or even Amazon. Just be sure to bring the old one in to make sure you get the right one.

I have a computer that starts up and then after 5-10 seconds, then just shuts down. I notices the fan on the CPU is not spinning and there is a light is on the mother board,

If the fan on the CPU is not running then that is very bad. Processors run very hot and will overheat quickly if they are not cooled. If its shutting down then its most likely a case of it over heating. You can go into the BIOS and see if you have anything set to shut off the computer at a certain temperature. This setting is to prevent the computer from being damaged from overheating. You can also let it run in the BIOS and watch the displayed temperature and see if it keeps rising or use a program like Speccy within Windows

I would get that fan replaced before using the computer again otherwise you might ruin your processor. When they go bad they will either start giving you problems in Windows with lots of errors or the computer wont boot up at all.

A screen comes up and it says the chassis fan is too slow. Press F2 to change BIOS or F1 to ignore.
It sounds like your computer has built in software to monitor your fan speeds. This may indicate that one of your fans inside your computer is spinning too slow which may or may not be a problem depending on how many other fans you have and how slow its actually spinning. You don't want to overheat your computer because that will cause hardware failure. You can try to go into the BIOS and see any messages or install a program like Speccy and see if it sees which fan is the problem. In most cases the chassis fans are easy to replace and fairly inexpensive. If its something you don't feel comfortable replacing then you may have to take it to a computer shop for repairs.

Upon startup I get a message saying low battery voltage, push F1 to continue. I push F1 and everything appears to be OK. Whats the problem?
It sounds like it's a message about your CMOS battery which is on your motherboard. It stores information such as the date and time and your hardware configuration. They are pretty cheap and easy to replace. You can find them at electronic stores or sites like amazon.com. You can look at it to get the part number and buy a new one and then take it out and replace it. Just make sure the computer is off and unplugged before doing so. Keep in mind that you may have to reset the date and time in the BIOS afterward.

I have problems with starting my PC and it starts with a really loud fan. Usually the loud fan stops but now it just keeps going. Why is that?
On many computers the fan spins up much faster during startup and the quiets down in a few seconds or so. If your computer is running hot then the fan may spin faster to try and keep it cool. This may be caused by things such as the environment you are using it in, being really dusty on the inside or if one of the other fans stops working. I would boot up into the BIOS and see if you have a temperature setting that you can watch while the computer is running to see how hot it gets. Or you can use Speccy within Windows to see the temperature. If the temperature stays at a reasonable level but the fan stays on high then it could be a problem with the fan or the controller for the fan's speed and one or the other may need to be replaced.
