Another thing to consider:
1) Who has updated beyong WinXP SP1?
2) Does anyone have Win2000 with or without this problem?
3) How many of you that have this problem have updated/haven't to WinXP SP2?
4) How about further, small...
You should talk with a few resellers.
I know that there definatley are keyboards available (if ever one breaks, etc.) to cover the warranties.
The only problem is I think they might cost a lot, something like $50 USD.
Well, if that 82 is without an intense load, then yes that's too high.
It's not like undervolting does anything bad except maybe you might loose some data that wasn't saved (which is why you save it before hand).
Anyways, you're really...
I know this won't be very helpful, but cable modems + USB = not fun.
I can understand you want to network, but you should think of some way different, such as buying a $10-20 Network card for your desktop.
