This article contains steps that may involve changing your BIOS or complementary metal oxide semiconductor (CMOS) settings or that may require you to make physical changes to your computer hardware. Incorrect changes to the BIOS of your computer may create serious problems. Microsoft cannot guarantee that problems that result from changes to your BIOS can be resolved. Change your BIOS settings at your own risk. If you need help with any of these steps, contact your hardware manufacturer and note that making either hardware or BIOS changes to your computer may invalidate your warranty. If you do not want to make hardware changes to your computer, you can take your computer to a repair center.
To resolve this issue, use one of the following methods: Make sure that you are using the latest BIOS revision for your computer. Contact the computer manufacturer to inquire about how to obtain and install the latest BIOS update that is available for the computer. If you are using an IBM computer with an AWARD BIOS version 4.5x, visit the following IBM Web site: http://www.ibm.com Microsoft provides third-party contact information to help you find technical support. This contact information may change without notice. Microsoft does not guarantee the accuracy of this third-party contact information.
The only thing that I can suggest is try to reinstall the operating system from the recovery CD or original software. If you do not have the CD, then you can also take assistance from any computer tech support provider such as AskPCExperts (http://www.askpcexperts.com).
