Thankyou for the speccy report. As your processor is soldered onto the motherboard and the motherboard is manufactured for the laptop case it is not an option to replace these parts.
Your Harddrive is showing a warning suggesting you would get the best improvement by replacing the Mechanical hard drive for a SSD drive.
This part of the speccy report is of concern.
