PC stürzt ab und startet neu Windows 10

If your computer suddenly stops responding while in Windows, you may be experiencing a computer lock up issue. For computer lock ups, there are steps you can take to attempt to discover the root cause.

NOTE: If the issue recently started, note any recent hardware or software changes before beginning troubleshooting, as reversing those recent changes may quickly identify the issue.

A piece of hardware may be causing the lockup. Try unplugging all devices from your computer, including:

• Printers
• Scanners
• Media Card Readers
• Small Media cradles (iPod, PDA, MP3 player, so forth)
• Digital Cameras and Video Recorders
• USB storage devices
• CDs or DVDs from all optical drives
• Docking station or port replicator

The only devices that you should leave attached to your computer are your monitor, mouse, and keyboard, if the computer is a desktop.

Once this is completed, unplug the computer from the wall, remove the laptop battery (if applicable) and hold the power button down for approximately 15 seconds. Then plug wall power back into the computer and attempt to restart.

If the mouse or keyboard is causing the lockup, go to the Dell Support Library page for Mouse, Keyboard, and Touchpad.

If you are unable to identify the issue by reverting recent changes or unplugging devices, you can troubleshoot using the steps that are listed below.

Windows may display an error code that is associated with the shutdown, restart, lockup, or error. The quickest way to find info on this is to use the search engine of your choice to look for your specific issue as Microsoft has detailed information for each:

To determine if your computer is experiencing a hardware problem, run the Dell Preboot System Assessment (PSA) Diagnostics. For information about how to run Diagnostics, and to determine the issue, see Dell Knowledge Base Article How to Run a Preboot Diagnostic Test on a Dell Computer.

If the onboard diagnostics and other troubleshooting have not identified the root cause of the lock ups, you may want to consider running the Quick Test or Full Scan at Dell personal computer Diagnostics. You can Run a Dell Quick Test using SupportAssist.

Often, lockups can be caused by outdated drivers or BIOS settings. Be sure to regularly update your drivers to take full advantage of your hardware and software.

Generally speaking, you should update your drivers and BIOS in the following order:

1. BIOS
2. Chipset driver
3. Video driver
4. Audio driver
5. Network driver
6. Other drivers

Try updating each of these drivers individually and then retest the computer to see if the problem continues. Learn How to Download and Install Dell Drivers

Blocked air vents can cause performance issues, as the computer may not be receiving the proper airflow and the processor may overheat. To protect itself from overheating, the processor slows itself down and this performance decrease can be interpreted as a lock-up. To ensure that this is not the root cause of the lock-up issue, perform the following steps:

1. Check the vents on the computer to see if they are covered with dust and not allowing heat and air to pass through. See the example that is shown in Figure 1 for a laptop vent and the example that is shown in Figure 2 for a desktop vent.
   
   Figure 1: Vent on the bottom of the Laptop with dust.
   
   Figure 2: Vent on the front of a desktop with dust.

2. Turn off the System.
3. Remove all power sources: Unplug the AC Adapter and Remove the Battery, or Unplug the Desktop Power Cord.
4. Use a compressed air can to blow the dust out of the vents. Be sure to hold the can at an upright (near 90-degree angle) and hold it 15-20 centimeters (6-8 inches) away from the target.

NOTE: Do not use your mouth to blow the dust out of a laptop. The moisture from your mouth can cause permanent damage. When using a can of compressed air, use according to the directions on the side of the can, as you can cause damage to the computer if used incorrectly.

Safe mode prevents noncrucial applications and drivers from loading. This allows us to eliminate the software as a possible root cause of the lock-ups or stops responding.

NOTE: When using safe mode, the video resolution is 800 X 600 and may make your icons and text appear larger than normal. Also, your desktop background is not shown in this mode. These are normal behaviors and do not require troubleshooting to repair, as they will return to normal when you log back into regular mode.

NOTE: Please note that when you log in to Safe Mode, your anti-virus program is disabled. Please use caution when connected to a network or the Internet while your anti-virus is disabled.

To boot into safe mode, follow the instructions below:

1. Start the computer.
2. Tap 'F8' on the keyboard immediately and every one second until the Dell logo screen disappears. From there, you will see the Windows Advanced Options Menu on the screen. (If the Windows Advanced Options Menu does not appear, restart the computer and try again.)
3. Select Safe mode with Networking and press Enter.
4. Log in as the administrator or as a user with administrative access.

For instructions on booting into Safe Mode, see the relevant link for your operating system:

In Windows 8 or Windows 8.1, learn How to Boot into Safe Mode in Windows 8 or Windows 8.1.

Open applications and test the computer in safe mode. If the symptoms exist in safe mode, continue the troubleshooting steps in this article. If the symptoms do not exist in safe mode, the issue is likely related to a driver or software and you may want to complete steps 6 and 7 to see if you can resolve the lock-ups or stop responding.

Be sure that your computer is running with the latest updates for Windows. Browse to the Windows Update website to be sure that your computer is fully updated.

If your computer is locking up or stopping responding while using a particular application, try uninstalling the application completely from the computer, then reinstall it and browse to the software vendor's website to update the software to the latest version.

NOTE: Notice: Before uninstalling any application, be sure to back up any critical data. Also, be sure you have the required media and product key to reinstall the software. If you are in doubt, check with the software vendor before uninstalling.

The use of multiple anti-virus software programs may cause your computer to lock up. Anti-virus programs come preinstalled on most Dell Computers, so customers sometimes install other anti-virus programs without realizing that there is already one installed. If you decide to install an alternate anti-virus software, it is important that you first uninstall any other anti-virus programs that may be running on your computer.

Choose only one anti-virus program and reinstall it. It is not recommended to have more than one anti-virus software program installed on your computer. Multiple anti-spyware packages that do not have an AV component do not conflict and can remain on the computer.

For anything virus, malware, and security related we recommend the content and videos on our Security and Antivirus page on the Dell Support Site.
