You should check your RAM, every year to year and a half,
for correct operation. I had two sets of RAM go bad on
the WinXP machine.
(Standalone test media, current OS is not a factor)
There was one motherboard, which accepted 0 to 8192MB of
RAM, and if you installed exactly 4096MB (2x2GB), the
"USB Overcurrent" would put a notification on the screen,
even though LEDs on the USB devices remained properly lit.
This was an address map bug in the BIOS.
Check google for the history of your motherboard/chipset,
to see if that may be a factor.
The ICH5 seemed to have a USB latchup problem. If the
USB Power contacts on the ICH5 were involved, it would
burn a hole right in the chip (system = dead). But
other failure modes would give lesser USB symptoms.
The ICH5 should be heatsink-free, so the label can be read.
82801EB (ICH5) Base
82801ER (ICH5R) RAID
I had a board with ICH5R, and it's dead. It died between
one interval of usage, and a couple years later, attempting
to boot it. PSU was OK. Mobo was not. Not an overclocked system.
USB port behavior was "normal". It seemed to be a Southbridge
issue, but... no burn mark.
