We want to see which may be the problem with Duvan's computer.
We know that the computer is running Windows 7 and it has 3 GB of RAM. There is also a relation between the sluggishness and the hard drive activity.
So from the given information, we can see that there are two problems.
1) Windows 7 needs between 1 GB and 2 GB of RAM, this would mean that just the operative system uses between 33% and 66% of the computer's total RAM, leaving really little RAM for other things. Increasing the RAM would help a lot with the computer's performance.
2) There may be a problem with the hard drive (the amber light going solid means that the hard drive is working constantly). Using a SSD (solid state drive) would increase drastically the speed at which the computer works (at least to have installed the operative system and important programs).
A cheaper way is cleaning and defragmenting the current hard drive so it works a little bit better.
