1. Why is my computer running slow?

The slowdown of your system might happen due to the amount of programs and ad-ons you have installed in your system, a driver or update that was not installed properly or even due to a virus or spyware that infected the system.

2. What should I do?

Basic tips include things like:

  • Uninstall programs you never use.
  • Restart the computer regularly.
  • Run fewer programs at the same time.
  • Defragment the computer’s Hard Drive.

Now, if that does not make any changes you can get your system back up and running as it used by following these steps:

A BIOS update can often fix problems and even add features to the computer's hardware functionality. It is recommended that you review the BIOS release notes to know the fixes and enhancements it apply to your system.

To download and run the BIOS update in your system:

  1. Browse to the Drivers and Downloads page.
  2. Enter the computer service tag (to get a concise list of drivers for your specific product)or select the product from the list of Dell Products.
  3. Under Refine your results select BIOS.
  4. Click Download File and choose the download method. Refer for instruction to download files using Download Manager .
  5. If you are using single file download, click continue.
  6. At the prompt to Run or Save, click Save and Run (Note the folder where the file is saved).
  7. A new window will appear, follow the instructions to finish the installation.

This step applies only for Alienware Desktops and it consists on accessing the advanced menu within the computer BIOS in order to disable the PCIe Gen3 option.

To access the computer BIOS just turn on the system and start tapping the [F2] key when the Alienware Logo appears. Once at the BIOS screen just use the arrow keys to move over the advanced menu and change the setting as mentioned before.

The Dell enhanced Pre-Boot System Diagnostics better known as ePSA is a tool built into the hardware of your system that will allow you to check the computer’s hardware from outside of Windows.

Based on the diagnostic findings you will determine if any further troubleshooting is required to fix a particular issue.

For further details as on how to run it and what to do in case any error is found while running these diagnostics please check the Running ePSA Built-in Diagnostics on your Alienware System article.

Support Assist is a software preinstalled in your Alienware computer that allows you to check the computer from inside of Windows.

If your computer is experiencing slow performance we suggest you to run the video card, hard drive and memory hardware scans. To know how to do this just check this article .

At the Control Panel under the Power Options you can see the different plans available for your system. It is recommended that you use the High Performance one. Even though it may use more energy, it favors the general system performance.

If you have high end applications that are not performing as expected, for example a video game, maybe the cause is that the computer is not assigning the correct video card to process the respective instructions. If this is the case, you can fix it by making sure the game or application is added to the whitelist in the video card control panel settings.

Sometimes the slow performance may occur due to an outdated driver, that’s why it is recommended to periodically check for updated drivers, especially in the case of your system video card.

The idea is that you prevent data loss in case the cause of the slow performance may be a defective hard drive. You can use tools like Support Assist or the ePSA Built-in Diagnostics to confirm if a hard drive is working properly or not.

If the hard drive is working properly then you may want to defragment it to ensure that files are arranged in an orderly manner to free space on the drive, reducing the time taken to read a file.

The best way to deal with viruses is to prevent them in the first place that’s why you should always run an antivirus software and keep it up to date.

Common symptoms of a virus besides the slow performance may include: unexpected messages popping up on the screen, programs that start automatically or the sound of your hard drive constantly working.

AlienRespawn is a software preinstalled on Alienware systems that contains a backup copy of all software originally installed on the system. If you run it, it will erase all data on the hard drive to have the computer with only the software that was installed at the moment that you received it; that’s why is recommended that you back up your data before proceeding.

To run the AlienRespawn just follow the instructions listed in this article .
