To save you as much time as possible, I’ve put together a list of six of the best and most effective tips for improving your Dell PC’s performance. Some of these tips you’ll find more useful than others, but I guarantee you’ll find what you need here to get your PC back to peak performance.

Turn Off HDR

HDR can add to graphic quality when using certain programs such as Netflix but requires a large amount of your PC’s resources and for the most part, can be turned off with little functionality lost for most users.

To accomplish this using Windows 10:

  • Open the Settings app using Windows Search
  • Select System
  • Select Display
  • In the Windows HD Color section, untick Use HDR

This should greatly increase your graphic performance and allow your computer to run faster. HDR is a feature that is seldom used by most users.

Disconnect External Devices and Restart

It’s easy to blame your PC for performance problems, but sometimes that’s misplaced. Anything connected to your computer can cause your computer to work harder than it should, causing it to run slowly.

Since this problem is easy to fix, try the following first: Unplug any devices connected to your Dell, such as external hard drives, SD cards, or printers. Then restart your PC without any accessories connected and see if the problem can be fixed. If it does, there may be a compatibility issue (for example, using an old printer with a new computer). Sometimes the device also works in the background – for example, if you set up automatic backups to an external hard drive, the PC slows down while files are copied in the background.

Do a Hard Reset

If your problem is caused by a temporary glitch in your system, doing a hard reset usually resolves everything. Perform the following:

  • Close all running programs and turn off your machine
  • Disconnect the power cable and remove the battery
  • Leave the computer turned off for 30 seconds
  • Within those 30 seconds, press and hold the power button in five to 10-second intervals
  • After 30 seconds, reconnect the battery to your laptop and connect the power cord

Turn it on at this point and see if the computer’s performance has improved. This should solve a large host of issues as this ensures the RAM is cleared.

Clean up Your Hard Drive

While memory, which stores all the data you are currently using, is often the cause of slow computers, a full hard drive can also cause performance issues. If your Dell hard drive is more than 85% full, you’ll experience a quick performance boost after cleaning it up. To do this, use a downloadable program called CleanMyPC – a tool that automatically keeps the hard drive clean.

Another way to clean up a full hard drive is to use an external hard drive or online cloud storage to store files. You can also remove applications you no longer use, perform a disk cleanup or delete temporary files.

Clean the Fan System

If your computer is older and you have never cleaned the fan, there is a possibility that dust deposits in the fan will cause the computer to overheat. This, in turn, will affect performance. First, locate the fan by finding the vent on the computer. Gently blow out the fan with a can of compressed air to remove the dust. Be sure to do this with the computer turned off so as not to damage the fan by turning it in the wrong direction as it tries to move.

Customize Power Options

Another method that can be used is customizing the power options.

  • In windows search, type choose a power plan and select it from the options
  • Select the High Performance option to be your default setting
  • Click change plan settings to customize your plan, if you would like
  • Furthermore, you can click Change Advanced Power Settings to change additional settings for performance

Customizing these options is an easy way to fine-tune your PC’s performance and get your computer running much smoother.
