Does you computer seem a little off or do the fans spin harder than they should for the load the system is under if so you may want to check your Bios Version and see if it needs updating.

To check the current Bios on your machine while windows is running we will do this

"Click on Start and then Run.

In the text box in the Run window, type regedit and click OK. This will open the Registry Editor program.

Note: Do not make any changes to any entry anywhere in Registry Editor to avoid causing serious system issues. These steps only direct you to view a registry entry, not to make changes.

Locate the HKEY_LOCAL_MACHINE folder under My Computer and click on the (+) sign next the folder name to expand the folder.

In the resulting folders, locate and click on the (+) sign next to HARDWARE to expand this folder.

In the resulting folders, locate and click on the (+) sign next to DESCRIPTION to expand this folder.

In the resulting folders, locate and click on the System folder.

In the results that appear in the window on the right, locate the SystemBiosVersion and SystemBiosDate entries.

The data in the SystemBiosVersion field contains the BIOS version for your motherboard. This field may also contain additional information such as the chipset manufacturer and BIOS manufacturer.

The data in the SystemBiosDate field contains the calendar date associated with the current BIOS version on your motherboard. The BIOS date can be useful in determining the current BIOS version from a motherboard manufacturer's website if the version is not clear in the SystemBiosVersion field.

Close Registry Editor without making any changes."

you can Find and check for updates for the Bios from your Manufactures site as well. you will most likely need to put in your Computers model which if a laptop is on the bottom above the barcode strip then go into the manuals & downloads sections and then select firmware.
Make absolutely sure that you download the correct Bios for your System ie windows xp/7/8 32/64bit if you flash the wrong image and for some reason it lets you I(now a days it wont most times) you will brick your computer.

Make sure while flashing through windows or the manufactures tool that you close out all other programs and that you touch nothing during the flashing even after it shuts itself down it will reboot on its own after it finishing flashing and must not be interrupted.

some of the manufactures Bios updates will have a all in one Gui flash tool that is nearly completely automated after you download the update and run it which is fine so long as it checks that you are flashing a compatible Bios version and it backs up the original.

Now most Geeks will tell you do not use the windows flash type utility and too go the extra mile for systems safety and download the Bios update and to rename it to something small like "2222" and to place it on a usb and to restart your computer and Enter Bios through F2 and then select your update location and update through Bios its self this is a safer way of updating and the likely hood of your pc being bricked is rather small so long as you have the proper Bios update for you motherboard and that you dont lose power during the flash i usually go with this method of updating Bios but it can take a few extra minutes to do but for the assurance of a working system afterwards i feel its worth the time.and i usually use [ Register or Signin to view external links. ] to create the bootable usb for the bios update seeing as i am lazy

*If you are updating a laptop, first make sure the battery is fully charged, and then plug into the wall power so you are not running off the battery. In the event of power failure, your battery will keep things running.

*If you are updating a desktop computer, it's best if you are plugged into an uninterruptible power supply (UPS). Like the laptop's battery, the UPS will keep everything running, while others are running around in the dark.


Feel free to add anything i missed so others can have a easier time updating and avoiding issues while doing so
