Windows 8 Touch Screen Troubleshooting 

 How do I check if my PC has a touchscreen?

Try using your finger to tap a tile on Start. If it’s a touchscreen, the app will open. You can also check your current system settings with your mouse:

• From Start, click the Desktop tile.

1. Point to the upper-right corner of the screen, move the mouse pointer down, and then click Settings.
2. Click PC info.
3. Under System, check the Pen and Touch setting. If your PC’s screen is a touchscreen, it will describe what input it supports.

   Touch input is on by default and can’t be turned off. If you expect your laptop or monitor to respond to touch and it doesn’t, check the manufacture’s website to make sure it supports touch and that you have the correct drivers installed.

 What do I do if I calibrated my pen and touch settings, and now I can't open the charms anymore?

If you calibrated your touch and pen settings, and now the charms don't appear when you swipe in on the right edge of your screen, it's possible that Windows isn't detecting the edge of your screen accurately because the screen boundary was reset during the calibration. Try following these steps to calibrate your pen and touch settings again.

1. Press the Windows logo key + W to open the Search charm.
2. Enter calibrate in the search box, tap or click Settings, and then tap or click Calibrate the screen for pen or touch input to open Tablet PC Settings.
3. Check that the monitor shown in the Display field matches the screen you want to calibrate.
4. Tap or click Calibrate, and then follow the on-screen instructions. To help make sure Windows can detect the edge of your screen accurately, try touching slightly toward the center of the screen when you touch the calibration points.

How to Install Turbo Boost Technology to Work

Intel includes a turbo boost technology feature on several processor models, such as certain Intel Core i7 models. Turbo boost increases the processor's default operating speed when the processor is not operating at the maximum allowed temperature and power specifications. As long as the processor remains under its limits, it essentially overclocks itself to take full advantage of the processor's power. The turbo boost setting is contained in your system's BIOS. It is typically turned on, but you may need to activate it manually if it becomes disabled.

Step 1Reboot your computer. Watch your screen for instructions on which button to press to enter "Setup" or "BIOS."

Step 2Press the button to get in to your motherboard's BIOS. This button typically is one of your F keys, ESC or DEL.

Step 3Use the arrow keys to navigate through your BIOS settings. Look for a "Performance" or "Processor Overrides" section in your BIOS. Each motherboard has its own BIOS settings, so the section may be named slightly different. You may also need to go to the "Advanced" area of your BIOS set up to enter any processor sections.

Step 4Highlight the Performance or Processor Overrides section and press "Enter." Select the "Turbo Boost" option. Press "Enter." Choose "Enable" and press "Enter."

Step 5Press "F10." Your BIOS setting changes are saved and your computer exits BIOS.
