If your computer is currently on, but does not display a picture, hold the power button down for a few seconds, this will power off your computer. If the computer continues to not power off, remove any power sources such as turning off the power supply on your desktop or removing the battery on your laptop. Turn the computer back on to initiate the bootup sequence. The BIOS (Basic Input/Output System) of your computer allows you to change the settings of your computer including the CPU (Central Processing Unit) fan speed. During the bootup sequence of your computer, you will have to hit one of the function keys, either F2, F8 or F10 depending on your manufacturer to get to the Setup Menu. If the computer is pre-built, check the user's guide on how to activate the BIOS Setup Screen. You may also see the function key to press on the BIOS splash screen during start up. Try pressing the key repeatedly during the startup sequence to activate the menu. When you activate the BIOS setup screen, find the listing of the CPU fan speed by navigating to the ''Hardware Monitor'' using the arrow keys on your keyboard then pressing Enter. The BIOS may show an alert if the fan speed is too slow. If there is no warning, identify what if the CPU fan speed is. Ensure the BIOS is set to automatically change the fan speed. BIOS settings will vary for most motherboards, refer to your computer or motherboard's manual for where the settings are located. In the hardware monitor, use the arrow keys to navigate to the CPU fan settings. Press Enter then use the arrow keys to change the fan profile information to match automatic or optimal settings then press Enter again. Verify the recommended fan setting in the user guide of your motherboard or computer. If the CPU fan speed is set at the recommended setting and is operating normally, the issue may be related to the graphics driver. You can also try controlling your fan's speed outside of the BIOS using a third party application such as SpeedFan if your computer supports these programs. Ensure that your computer is compatible with fan controlling software by checking with the compatibility documentation on the developer's website. You may not be able to use these programs within Windows as the BIOS will likely override any settings. If using a pre-built computer, check the user's guide or support to see if there are any programs dedicated to controlling the fans from pre-installed software. If the fan is damaged or is not achieving appropriate speeds identified by the computer, it may need to be cleaned, repaired or replaced. You can attempt to overclock your CPU which will cause the fan speed to speed up from within the BIOS, however this will cause more wear on your CPU and give it a shorter lifespan.

If you are using an envelope that has a see-through "window" where the recipient's name and address will show through, it is very important that you have the letter formatted so that this information lines up correctly. To format a business letter, you should first ensure that your margins are set at 1 inch (2.5cm) on all sides in your word processor. Make sure that you have the text aligned to the left hand side of the page while you are typing the date and the recipient's address. The letter should be single spaced except for in-between paragraphs. Between paragraphs there should be two spaces. The entire letter should be left aligned. There should be approximately 2 inches (5.1cm) of blank space from the top of the page to the place where you type the first line of text (the date). Type the date out in full (e.g. April 1, 2016 instead of 4/1/16). Hit enter two times so that you have a blank space between the date and where you will type the recipient's information. Type the full name of the recipient (e.g. Mr. John Doe), hit enter and type the address of the recipient, hit enter again and type the city, state, and zip code of the recipient. Be sure to include a space between the recipient's contact information and the salutation. " To take advantage of the window of the envelope, you will need to fold the letter so that the recipient's name and address face outwards. This version of folding doesn't afford the same privacy as folding the letter inwards, but it must be folded this way if you want the name and address to show through the window. If the letter contains sensitive information, it may be best to use a standard envelope with no window. Having the text facing down will make it easier to see where the name and address are when you fold it. If you have done this right, you will not be able to read the text of the letter. The letter should be text-side down, but make sure that it is also arranged so that the recipient's name and address are closest to you. If you have done this right, when you peek underneath the paper, the name and address of the recipient will be the closest thing to you. Take the upper third of the paper and fold it down towards you. If you aren't sure how far that is, you can also align the envelope under the center of the paper to use as a guide. Take the bottom third of the paper and fold it up and away from you. The name and address of the recipient should now be visible to you. Take the letter so that the recipient's information faces the front of the envelope. Insert the letter so that the information shows through the window. If you can't see the recipient's information, you might have inserted the letter upside down. Remove the letter and turn it around (the recipient's information should still face the window).
