I would like to know if there is any way I can make my computer faster and/or reduce the amount of disk space that has already been consumed.
Here are the Specs
Hard Disk Space: 151 GB out of 221 GB
Installed Memory: 3.00 GB
PS: I checked my Windows Experience Index, and this is what I got
Memory (RAM): 4.9
Gaming Graphics: 3.1
Primary Hard Disk Space: 5.1
Overall [ determined by the lowest subscore ] : 3.1
Is there any way to get higher ratings for these criteria?
PPS: I'm told that it's possible to raise my PC's memory without changing any hardware (i.e. through software). Is this true? If so, are there any safe websites where I could download the software to do this?
