4: Update Drivers and BIOS

In many cases, lockups can be caused by outdated drivers or BIOS settings.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 system to see if the problem continues.

6: Uninstall, Reinstall and Update Software

7: Look for Multiple Anti-virus Programs

The use of multiple anti-virus software programs may cause your system to lockup. Anti-virus programs come pre-installed 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.

To check for malware on your system and to ensure that your computer is up to date on security software, visit Dell Knowledge Base Article, "Protect Your Computer or Remove Malware in Microsoft Windows"

9: Use System Restore
