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.
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:
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.
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.
This process is known as clean boot and it is performed to start Windows by using a minimal set of drivers and startup programs which helps to eliminate software conflicts that occur when you install a new program or run an update.
To know how to perform this process check out the video below:
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.
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 .
