So here’s the problem: you have just bought and installed a new quad-core CPU. But when you checked Windows device manager, it says that you only have a single-core processor. Not to mention the performance boost you were expecting from the new CPU can hardly be felt!
The reason is that your BIOS, the firmware of your PC, is obsolete and has no support for quad core CPUs. The problem can also occur when you install a new graphics card or if you have changed settings. Even small changes in the BIOS can have a huge impact on your PC’s hardware components.
Now here’s the good news. It can be fixed! The remedy is to update Basic Input Output System (BIOS) so that it can support your new hardware. But be warned! When updating BIOS, be very careful.
You see, updating it means overwriting the basic information needed by your PC after you switch it on. If something goes wrong or some of the essential data are missing, your PC will not boot.
That said, it can be done even by an average PC user. You should prepare for the update by following the steps below:
Find out the Exact Model
First off, you should find out the exact model of your PC’s motherboard. This can be found in your motherboard’s manual. If your manual is nowhere to be found, don’t worry. The model name (ex.: P5E3 Deluxe) and even the manufacturer’s name are usually printed on the board or on a sticker on one of the card slots. Along with that, take note of the revision number.
Read Boot Screen
Along with the tip above, the boot screen also gives important clues about the board’s manufacturer, model, and BIOS version. To read it, press the DEL, ESC or F2 once when the manufacturer’s logo is displayed after booting.
Download the Update
The upgrade files can usually be found and downloaded on the motherboard manufacturer’s website.
For complete PC systems like as Dell, Fujitsu-Siemens, etc., take a look at their website first and search for your PC model. After entering the model name, you will usually find the components of your PC system along with other downloadable files including the appropriate update files.
Always compare the specifications. Is the motherboard name correct? Is the BIOS available on the Internet more current than that on the motherboard? Basically, when updating the firmware of your PC, there are two necessary parts: the program needed to write on the flash BIOS chip and the actual update file.
Weigh the Risks
Even if you follow all the necessary precautionary measures, it is possible that your PC won’t work after the update and all attempts to restore it might even fail. Therefore, you should check what the update brings. Please read the release notes for the files. They are usually supplied as a TXT file or appear grouped under the download link.
