PC Status	Overall this PC is performing way below expectations (6th percentile). This means that out of 100 PCs with exactly the same components, 94 performed better. The overall PC percentile is the average of each of its individual components. Use the charts in the benchmark sections of this report to identify problem areas.
Processor	With a relatively low single core score, this CPU can handle email, light web browsing and basic audio/video playback, but it will struggle to handle CPU intensive tasks. Finally, with a gaming score of 29.7%, this CPU's suitability for 3D gaming is very poor.
Graphics	1.13% is too low to play 3D games or use CAD packages. (Note: general computing tasks don't require 3D graphics)
Boot Drive	44.3% is a reasonable SSD score. This drive enables fast boots and responsive applications.
Memory	8GB is enough RAM to run any version of Windows and it's sufficient for the vast majority of games. 8GB is also enough for moderate file and system caches which result in a very responsive system.
OS Version	Although Windows 10 is not the most recent version of Windows, it remains a great option.

Very high background CPU (100%). High background CPU reduces benchmark accuracy. How to reduce background CPU. CPU throttled at 33% by Windows.
