Day 40 [Research: "Why is my computer slow?" - Day 2]

Continuing through the pdf file, I've learned that if a program like Angry Bird is not working and you've tried everything such as restarting the computer, uninstalling and re-installing the program and still not work, it's due to a corrupted file. When uninstalling a program, you don't permanently remove everything. What's left is the folder that has files that support the program but not the program itself so when re-installing, you're not changing anything. To solve the problem you have to uninstall the program and remove the folder that's left in the hard drive and re-installing it and hope there's no corrupted data. I also come across some information about SSD(Solid State Disk). Defragmenting an SSD is not recommended by many people due to one thing, it reduces the lifetime of the hardware. Writing on the SSD wears it down and defragging it will mean there will be a lot of writing.
