How to Fix Blue Screen Problem on Desktop/Laptop





  How to Fix Blue Screen Problem on Desktop/Laptop

Blue Screen is usually hardware or driver related.. Most Blue Screen show a STOP code that can be used to help figure out the root cause of the Blue Screen.  

Important: Below are general Blue Screen troubleshooting steps.
Note: Some of these steps may require you to start Windows in Safe Mode.
If that's not possible then skip those steps.

Time Required: It might take you several hours to fix a Blue Screen, depending on the STOP Code.
Applies To: Any version of Windows, including Windows 8, Windows 7, Windows Vista, andWindows XP.

Here's How:


1.  The most important Blue Screen troubleshooting step you can take is to ask yourself what you just did.

Did you just install a new program or a piece of hardware, update a driver, install an update, etc.? If so, there's a very good chance that the change you made caused the blue screen.

Undo the change you made and test again for the STOP Error. Depending on what change you made, some solutions might include:
  • Startup using Last Known Good Configuration to undo recent registry and driver changes.
  • Use System Restore to undo recent system changes.
  • Roll Back device driver to version prior to your driver update.
2.  Verify that a minimum amount of free space is available on your Windows partition. Blue Screens and other serious issues, like data corruption, can occur if there's not enough free space on your primary partition used for the Windows operating system.
Note: Microsoft recommends that you maintain at least 100MB of free space but I regularly see problems with free space that low. I usually advise Windows users to keep at least 15% of a drive's capacity free at all times.

 3.  Scan your computer for viruses. Some viruses can cause a Blue Screen, especially ones that infect the master boot record (MBR) or boot sector.
Important: Make sure your virus scanning software is completely up to date and that it's configured to scan the MBR and boot sector.


4.  Apply all available Windows service packs and other updates. Microsoft regularly releasespâtches and service packs for their operating systems that may contain fixes for the cause of your Blue Screen.

5.  Update drivers for your hardware. Most Blue Screens are hardware or driver related so updated drivers could fix the cause of the STOP error.

6.  Check the System and Application logs in Event Viewer (7/Vista | XP) for errors or warnings that might provide more clues on the cause of the Blue Screen.

7.  Return hardware settings to default in Device Manager. Unless you have a specific reason to do so, the system resources that an individual piece of hardware is configured to use in Device Manager should be set to default. Non-default hardware settings have been known to cause a Blue Screen.

8.  Return BIOS settings to their default levels. An overclocked or misconfigured BIOS can cause all sorts of random issues, including Blue Screen.
Note: If you've made several customizations to your BIOS settings and don't wish to load the default ones then at least try returning clock speed, voltage settings, and BIOS memory options to their default settings and see if that fixes the STOP error.

9.  Make sure all internal cables, cards, and other components are installed and seated properly. Hardware that's not firmly in place can cause a Blue Screen so tryreseating the following and then test for the STOP message again:
  • Reseat all internal data and power cables
  • Reseat the memory modules
  • Reseat any expansion cards

10.  Perform diagnostic tests on all hardware you're able to test. It's highly likely that the root cause of any given Blue Screen of Death is a failing piece of hardware:
  • Test your system memory
  • Test your hard disk drive
If a test fails, replace the memory or replace the hard drive as soon as possible.

11.  Update your BIOS. In some situations, and outdated BIOS could cause a Blue Screen due to certain incompatibilities.

12.  Start your PC with essential hardware only. A useful troubleshooting step in many situations, including Blue Screen issues, is to start your computer with the minimum hardware necessary to run the operating system. If your computer starts successfully it proves that one of the removed hardware devices was the cause of the STOP message.
Tip: Typically, the only necessary hardware for starting your PC through to the operating system includes the motherboard, CPU, RAM, primary hard drive, keyboard, video card, and monitor.

Tips:
  1. Find out that hardware is the cause of your Blue Screen? Try this:
    • Replace the hardware.
    • Update the hardware's firmware.
    • Make sure the hardware is on the Hardware Compatibility List.
    • Check with the manufacturer for support information.
     
  2. Find that a software program is the cause of your Blue Screen? Try this:
    • Reinstall the software.
    • Check for and install any available program updates.
    • Check with the developer for support information.
    • Try a competing program.
     
  3. Is your PC restarting before you can read the STOP Code on the Blue Screen?
    Most Windows PCs are configured to reboot immediately after receiving a serious error like a     Blue Screen. You can prevent this reboot by disabling the automatic restart on system failure option.

How to Turn On/Off Damaged Power Button on iPhone/iPad

Image
If you're an iPhone or iPad user, then you might not realise just how much you end up using the power on your phone. The home button is essential to navigate through your device, and the use of the volume buttons and the mute switch on the side is pretty obvious too, but if your power button stops working, you can't turn your phone off - or back on again for that matter. It's also pretty easy to damage, with external factors such as excess humidity or dust that can make it stop working. You can get by without switching off the iOS device, but it is always good to be able to turn the phone off if needed. These simple steps to switch off the device without touching the power button could come in really handy. Open Settings . Go to General > Accessibility . Scroll down to the section labelled INTERACTION and tap on AssistiveTouch . On the next screen, toggle AssistiveTouch to the green On position. A white circle with a grey box will appear
