Yesterday evening I ducked out to visit a job site and resolve a landscape lighting issue (I had used an undersized wire nut and 2 wires "slipped" out - I brought the larger ones and re-connected - easy fix!).
When I returned home my screen showed an error message - a failure of my system - and even after running a diagnostics program it didn't resolve anything.
Fortunately I had my laptop so accessed the Internet and dug around until I was able to diagnose and resolve the issue - apparently due to a
failed RAM memory stick. 
I just got done ordering a new set (4x1GB) of them which I will install just to be safe. I had only 2x1GB so this will also result in a doubling of my RAM.
For a while there....I didn't know how this would end up. In no way shape or form do I know that much about computers except the very basics.
My machine is a DELL Vostro 200 w/Vista Home Basic 32 bit OS purchased 4 years ago. It has served me well and I am impressed I was able to resolve my issue and am now back up and running.
Whew!
PS - The BSOD is this in case you didn't know.....
