If Windows keeps crashing, it could be a software issue or a more general performance issue. Regular performance testing helps you prevent the computer from crashing and when it does, you can often fix it by taking a bit of pressure off the processor and performing full-scale diagnostic testing. You can increase the speed of your computer both in the short term and in the long term so that Windows can run smoothly.
Part 1 of 3: Perform full-scale diagnostics and reinstalls
Step 1. Defragment the hard drive
By using this solution, you reorganize the data and your computer will have less trouble finding it when you ask for it, reducing the risk of it crashing. To access this tool, simply click on Programs> Accessories> System Tools> Defragment Disk.
- Each action you do on the computer physically moves the data away from each other on the hard drive, making it more time for the computer to find it. Defragmentation corrects this problem and it can take anywhere from ten minutes to several hours depending on the size of your disk.
- See How to Defragment a Disk on a Windows Computer for more information.
Step 2. Format the drive and reinstall Windows
Sometimes uninstalling and reinstalling applications can help you make the computer run faster and the same is true for Windows. Formatting the drive erases all files on the primary drive to prepare it to reinstall Windows from the installation disc.
- Make sure to back up your data first! Formatting will erase everything on the hard drive.
- On Windows 8 and later, you can use the command Refresh so that Windows reinstalls itself, without a startup disk and without erasing your data.
- Take a look at How to Reinstall Windows 7 and How to Reinstall Windows XP for more information.
Step 3. Go back to a previous operating system
If your computer has only the minimum of requirements to run your current operating system, you may improve its performance by downgrading to an older system. See how to downgrade Windows 8 to Windows 7 for more information on this operation.
Part 2 of 3: use quick little tricks to improve speed
Step 1. Update the applications
Make sure your programs (including Windows) are up to date. In general, the newer versions are also the ones that work the best.
- Check and install Windows updates by clicking Windows Updates> Check for Updates> Install Updates.
- Many programs will notify you of updates, but you can also do a manual search for the most recent version or you can take a look at the update tools for that program to ask it to. check regularly for the presence of these.
Step 2. Close unnecessary applications
Programs that you leave running in the background take up a lot of RAM, which slows down the computer. To find out which programs are running at any time, take a look at the icons along the application panel or open the task manager.
Step 3. Limit Startup Programs
Access the configuration tool on startup by typing msconfig.exe in the search box and launching the program. Click on Start-up to access the software that starts automatically at startup.
Otherwise, Microsoft also offers a downloadable program called "Autorun" which gives you this kind of access as well as other options for choosing which programs to launch automatically when you start your computer
Step 4. Turn off visual effects
Windows offers about twenty different visual effects (such as shadow effects or animations when menus open and close) that can slow down your system. You can turn these effects on or off, or let Windows choose the optimal settings depending on your computer's performance (this is recommended).
- Access the special effects menu by clicking on Control Panel> Performance Information and Tools> Adjust Visual Effects.
Step 5. Uninstall unnecessary applications
To uninstall a program, enter the control panel and click on Add / Remove Programs before selecting the program of your choice and clicking on Modify Delete.
For more information on how to do this, you can check out How to Remove Unwanted Software from Your Computer
Step 6. Delete unnecessary files
The built-in hard drive cleanup tool scans for unnecessary files to prevent hard drive mess and improve performance.
- Access this tool by clicking on Settings> Control Panel> Administrative Tools.
- Remember to empty the recycle bin regularly. Files continue to pile up on it if you do not empty it regularly, which can decrease the performance of the computer.
Part 3 of 3: take care of the computer regularly
Step 1. Restart it regularly
This action frees up the computer's memory and closes any programs that may be running in the background. You should do this every week.
Step 2. Scan with the antivirus
A regular scan can identify many problems that could slow down the performance of your machine. Use the Windows built-in antivirus (Defender) or choose one from the many free options online.
Step 3. Clean the registry
This step is rather reserved for advanced users, as it involves significant changes in the system settings, which is why you need to be careful. Go to the registry editor (regedit) and don't forget to make a copy of it before you start. From the editor, you can remove old apps, eliminate unwanted programs on startup, and adjust your administrator account settings. Take a look at How to Clean Windows Registry Manually to find out how.
While there are many software programs that also allow you to clean the registry, it's usually best to take the time to do it yourself for best performance results
Step 4. Open the tower and clean the computer
Dust can slow down many computers. For this method, you will need to unscrew the plate on the side of the computer and use a compressed air tool to clean off the dust. Be careful during this step, as the inside of the computer is very delicate.
- Find out how to properly maintain and clean a PC and follow the instructions.
- Pay particular attention to the dust found on radiators and fans.
- Launch the Windows Cleanup Tool. In recent versions of the operating system, there is a tool that can eliminate unused shortcuts on the desktop and improve the performance of the computer.
- Uninstall all software from the control panel. Don't just delete the shortcut.
- Use the scheduled cleaning wizard. This program helps you remember to clean the hard drive, defragment it, and do other maintenance.
- Use care when handling computer parts, as they can break easily.
- Watch out for viruses that might accompany your online downloads. Scan compressed folders before extracting them, executable files, and anything else you think is questionable.
