SSDs are the best solution for a slow pc. Whether it's booting or waiting for search results, you can expect a speed increase. They're a bit pricy but they consume less electricity, so you can get your money back through electricity bill savings(might take a while ). My rig is an average gaming pc(optimism). The biggest problem is storage space I currently have a 500gb hdd that i salvaged from my laptop, the previous desktop hdd is dead...
So a new SSD for my OS would be amazing!
Thanks for the opportunity.
