If your town is big enough to have a best buy it surely must have a REAL computer store.
It looks like your grandparents system is about the same age as my parents system as it's equipped pretty much the same. some hp out of the box junk. BUT, theirs has a full 7200rpm hdd.
I would guess that it's suffering from junk file itis, when the user never uninstalls anything.
Go through the windows uninstall software window and ditch any bloatware. printers and cameras are bad for it I find,
Give it a swipe with CCCleaner
run MSConfig and take everything you can off the startup. you should end up with just sound driver, antivirus and graphics driver. Theres no need for itunes, java and adobe to be checking for an update every power-up.

If that helps you may have just saved the install. If not just reinstall windows see how that goes.
If you do put money into it I would suggest going this way. If you can find a 2x2gb ddr2 kit cheap or used go for it but it's probably unnecessary.

Like someone eluded to earlier on a system of that age to add even a $50 GPU will take alot of load of the processor and ram.
I own and have used one of the accelerator cache ssd's, I found it to work flawlessly. However it (and any ssd because of trim) only work with windows 7. It gives you i would say 70-80% of the performance of an ssd. anything you use regularly opens instantly.
And of course why would you keep an old psu in there?
