How do you find out what is slowing down my PC?

One of the best, and freeways, to find out the source of a problem, is to make changes to your PC sequentially.

This means installing new software, adding new hardware, and more, since you can then tell which new addition to your system is causing the performance lag.

The usual culprits are antivirus tools running in the background, and that is why many of them come with built-in optimization tools in order to compensate.

Another way of finding out what is slowing down your PC is to simply look into the Task Manager and see what is using up most of your RAM, CPU, and how many items you have configured for automatic startup.

Why is my PC so slow and unresponsive?

Before all else, make sure that your PC isn’t too dated for the programs that you are trying to use, or that not too many programs are running unnecessarily or idly in the background.

Additionally, make sure that your PC’s registries and DLLs are running accordingly. If you notice that these are indeed the problem, then a good registry cleaner will do you a world of good.

How can I fix my slow computer?

As mentioned above, a complete system reset is always a surefire solution to fixing a slow PC, although it is also the method with the most drawbacks as well.

That is when a solid and reliable Windows 10 optimization tool can come in handy, as it will completely clean, repair, and boost your PC’s performance in no time, among other features.

An optimizing software tool will delete the unused keys from your registry and other temporary files that are slowing down your computer.

It will also make sure certain settings don’t conflict with each other. Choosing a reliable optimizer software can get quite difficult since there are so many of them and you need to pick one that will fix your computer rather than make it worse.

This list will go through some of these options to help you pick the one that might work for you.

These are some of the best PC optimizers available on the market. You just need to pick the one that works the best for you.

Keep in mind that there are optimization tools for Windows 7 as well, so if you’re still using it, there’s are options out there for you as well!

Moreover, it’s always advised to make backups before running such a tool – which is a feature most of them offer as well. What’s your favorite weapon of choice?
