Sorry i couldn't offor better solutions.
My personal rules of thumb when it comes to IT can roughly be summarized, (remembering that in cost efficiency per performance standard desktops are best whilst ultrathin notebooks and laptops are worst), as follows:
In Tech Support 90% of software errors are not software errors but user errors, (not aimed at you btw, just the starting point).
In Tech Support 90% of actual errors are with the software.
In tech Support 90% of those Software errors are due to Viruses, Malware, and corruption caused by them.
In Tech Support 90% of performance issues are with the hardware.
In Tech Support 90% of the monetary cost is hardware
In Tech Support 90% of the time is software.
If your system was a desktop, you could fix it for 50-60 UK pounds, (no idea what country your in), plus paying someone to install it, (a few tens of pounds at most), a laptop just to get and install an exact duplicate of your current drive would cost you £150 pounds, and given the specialized knowledge and tools, (and drive cloning), likely required to install it, probably the better part of a £100 in techie costs. Getting somthing better is going to cost you a good bit more if you can even find it.
