Why is the computer too slow?

The usual suspects are antivirus running in the background. Besides, this is the reason why many security solutions modernize their infrastructure by adding tune up utilities to AV packets .

First and foremost, make sure your PC meets the specs required by the programs you're trying to run. 

The compatibility issue may be implicit, but software conflicts are among the most common reasons behind excessively slow system crashes or freezes. 

Make sure there aren't too many programs running simultaneously in the background. Then, also check that your DLL/registry/system files are not affected by computer corruption. 

For this purpose, you can also try a slow PC cleaning software that will speed up your system in a graspable manner.

Good software to optimize your PC will automatically check all these aspects and more. So why not give it a chance?
