Yes it was an exact match and it fit very tight. When I say move my computer, I mean maybe 3 times..I moved it to a temp desk when my desk desk area was being built, and I moved it to add a new modem and I moved it to add new ram..I don't mean to imply I'm carrying it all over the place ..all 3 times this same happened but it recovered until this last time. I think I'll start all over from the ground up and see if I can isolate anything..but it does seem it's a "hardware" issue am I correct? I may also replace the ide cables.
