I have a suggestion for you based on McGs suggestion to get a new computer.
In 2007 Dell sold a gazillion Latitude D630 laptops to businesses across the world. Built like a tank with dual core and 2 gigs of memory and an 80 gig hard drive(these are real good things) the D630 was state of the art.
Now in 2016 they've been unloaded on the refurbished market and are showing up at Walmart for as low as $118.
I bought one last year and man, is it a joy to use.
It comes with a free update to Windows 10 which I love.
All my browser problems disappeared and getting on the internet is fun again.
I know change is scary but you're gonna have to leave that old clunker soon.
For $118 you can't go wrong
