I agree with xrobwx71. You are greatly limited by having 32-bit Windows instead of 64-bit. Adding more RAM typically provides the most bang for your money but due to the way 32-bit maps hardware devices in memory, the maximum amount of RAM it can support is 4GB.
There may be one thing you can do to help. You are showing only 2.44GB of usable RAM. This suggests to me your system is using integrated graphics and not a separate graphics card. With integrated graphics, a big chunk of system RAM is stolen... err... "shared" with the integrated graphics solution. This is fine for basic office or school tasks, doing email, watching YouTube videos, or updating Facebook. But for more demanding tasks, it is another bottleneck.
If your computer supports adding a graphics card, adding a card may provide a noticeable performance boost. The graphics card will include its own RAM on the card that is dedicated for graphics processing. So installing a card will free up that stolen... err... shared system RAM and should give you at least 2.8GB of useable RAM, often 3.2-3.4GB is realized. So not only would you have dedicated RAM for graphics processing, you also would have a little more RAM for your CPU to use. All good for better performance.
With more RAM, the system will be able to keep more higher priority data in faster RAM instead of having to swap (cache) it into and out of the Page File as often. If your Page File is located on a hard drive (instead of a SSD), that may provide a little performance boost too.
Depending on the card, it may also have a better graphics processing unit (GPU) than the integrated solution too for even better graphics performance.
HOWEVER, graphics cards are often the most power hungry devices in our systems. So
before buying and installing any graphics card, it is essential to verify the current power supply can support the card too, and if not, the power supply
must be upgraded first.
Unfortunately, most factory made computers come with power supplies that are barely adequate to support the hardware they come with. So if you plan on upgrading to a graphics card, you should plan and budget for a new power supply at the same time.
Most card makers publish the power specs on the card's website. Or, you can use a good PSU calculator and the best and only one I use and recommend is the
eXtreme OuterVision PSU Calculator. You plug in your components and it will calculate your minimum needs and recommend a suitable size power supply for those needs. This is much better than guessing or picking arbitrary numbers out of thin air, and much easier than researching all the individual components yourself.
That said, sadly, many factory made computers from the big makers like HP and Dell also use proprietary components - especially in their entry-level computers.
This means you may have very limited (if any
) power supply upgrade options. So clearly, some homework will be needed.
