15.6 Laptop with Windows 10 (Misterton DN10)

15.6 laptop, originally purchased from Personal Computer Specialists around 6/7 years ago (Cosmos). 500 SSD drive, which was partitioned off and had a bit of a meltdown on that partition early this year so given its age will need replacing. Nvidia GeForce graphics card and a backlit screen. The innards were cleaned out last year and a new battery was installed earlier this year. SoundBlaster Cinema card (label has come off). Backlit keyboard. Regrettably getting slower and slower to start and no chance of being upgraded because of its age and I already have another 'spare'.
