Hi,
Upgrading a malfunctioning machine is rarely a good idea. As the problem
continues, the source is probably a hardware component failing. If you run
the memory diagnostics (don't just listen to a manufacturer, run the
diagnostic tools in Windows or one of the many free ones available) and a
diagnostic on the hard drive and they both pass, then the next steps is to
either locate a qualified technician or swap in known-good parts starting
with the power supply, cpu, and if it still continues, the motherboard.
