Not likely the OS.
Coincidently, I just recently replaced my trusty old 12 year old Toshiba A505 with a new MSI laptop. Mine even still had the original battery. The laptop still worked but it just was not meeting my needs anymore.
Your symptoms do suggest possible heat problems. If the case has never been completely opened to expose the full interior for a proper cleaning of all the heat trapping dust, I sure would recommend that. You also need to make sure the fan(s) are spinning properly. Make sure the laptop is stilling on a hard flat surface to allow for air underneath. A self-powered cooling pad might help. I recommend blasting a desk fan from the side across it and see if freezes continue.
That said, 12 years is really good run - but it is time to replace. Too bad Toshiba no longer makes laptops.
