You're right ..... that system should not be all that slow.
Unfortunately new computers often come with a fair amount of bloatware and as a consequence you may have some programs, processes and services starting up when you boot your computer that are resulting in a performance hit.
You might want to try clean booting the system and see if that provides any relief...

Easily done, easily undone.
Basically you're just disabling all the Startup Items and All
non-Microsoft services.
Be sure to check the box to hide Microsoft Services, as you don't want to accidentally disable any of those.
After configuring your machine to Clean Boot, if that seems to provide any relief from the problem you will then have to take some time and determine what the offending program, service / process might be.
Carefully and deliberately one non-Microsoft service at a time or in very small groups re-enable them, rebooting after each change to observe any changes. Then graduate to the Startup items again rebooting after each change.
Understanding that in some cases, a Startup item may have a non-microsoft service associated with it and as a result you may not notice the impact until both the Startup item and the service are re-enabled.
Additionally, assuming that, that is a 64 bit system, you might want to consider a RAM upgrade.
Doubling it from 4 to 8 gigs will likely help some.
Especially if it is not using a dedicated discrete video card. It will likely be sharing some of your RAM with the onboard Video, leaving you with less that 4 gigs available to the OS.
