what’s wrong with the Sony? That does not sound like a bad machine
Have you tried running CCClean and putting a thumbdrive Ramdisk?
You biggest issue seems only to be the 4G of ram. You’re not a real man unless you’ve got at least 8 gig of RAM
1) defrag
2) put a 4Gig thumbdrive and use ‘readyboost’
3) put in another 4 gig of RAM
4) Run CClean and clean up your files and registry
5) Run antivirus scan and MalwareBytes.
I bet it feels like a new machine. Your description of ‘tired’ makes me think it just needs some cleanup. Hardware either works or it doesnt

Why do I want a thumbdrive? What is it? Is it like a SSD but not in the box?
I can feel the hair growing on my chest as I ponder adding another 4G of RAM. Somewhere.
