[GTALUG] computer hardware testing tools.

[Karen Lewellen]

Hi folks,
What I am seeking is an open source program that tests aspects of say your 
motherboard.  that the serial ports or parallel ports work, that the USB 
ports are sound etc.
I am asking  because due to an as of yet not fixed hydro problem in my new 
apartment, the occasional power surges, even with machines attached to 
protectors, are causing slight damage to hardware.
Need to know how much as I only have so many computers I can use.
Any program ideas?
Will be sharing suggestions with someone hopefully helping me 
troubleshoot.
Thanks,
Karen
