Is it worth upgrading a 5 y.o. PC?
What do you use your computer for?
What do you have now?
What do you plan on getting?
If you use your computer only for Internet and business, a 1.5 GHz CPU
with 512MB - 1024MB of RAM will seem as fast as anything else. OTOH
for games you may need to upgrade the CPU, motherboard, and graphics
card, but I don't know if it's cheaper to buy those components or buy
a whole computer with comparable components.
If your current computer has only SATA I hard drive ports (150
megabytes per second maximum speed), you may have problems with
Hitachi or Samsung drives because they don't have a jumper to select
between SATA I and SATA II, unlike Seagates and Western digitals, and
some SATA I motherboards don't handle SATA II properly. Intel's do,
but apparently Nvidia's and VIA's do not. A PCI SATA controller card
can get around this, but PATA-SATA adapters that go between the drive
and existing controller aren't very reliable.
Another thing to consider are the conditions of the fans (in the power
supply, CPU cooler, and graphics card cooler) and electrolytic
capacitors (PSU, motherboard, graphics card). Japanese brand
capacitors that old tend to still be in good shape, a bad batch of
Nichicons being a famous exception that plagued Dells and Macs made
from about 2003-2004. But Taiwanese and Chinese caps tend to fail a
lot sooner, so you should look for any that are bulging or leaking
(see
www.badcaps.net). That's not easy to do with PSUs unless you
open them up, which you shouldn't do because there's high voltage in
them, sometimes even after they're unplugged. OTOH even lots of new
products are made with junk capacitors and will probably fail before
old stuff containing good caps (like my TV from the 1970s that's had
only two original caps go bad)
Why don't you just use one of those healing crystals on your
comptuer?
