I'm glad there are people "out there" who are willing to give self-repairs & modifications a try.
When television came out it was such a mystery to 90% of those using them. So there we sat watching until a 'little blue dot' appeared on the screen or 'vertical roll' took over in the middle of Rawhide or Bonanza... or 'snow' obscurred Disney's Wonderful World of Color. There were of course reasons not to open the back of the TV up and fiddle around. Capital "V" for voltage.
Computers are different, they should not be scary to work on or with. The warnings and taboos associated with things you plug in to the wall do not apply in all the same ways. Simple concern over static electricity, use of strong magnets and common sense regarding the AC current, like don't hold the prongs of the plug as you place it into the socket, guide the hardware repairs/mods. Manufacturing techniques & standards have made things much more accessible than fixin' a toaster IMO.
As for the malware and software configurations and/or conflicts... how else better to deal with them than to talk about it?
Millions of users are working on a daily basis with hundreds of programs, applications & utilities loaded onto windowsXP alone. A very large majority of those users have been self-taught by basically trial & error with the help of tutorials, user guides and on screen help tips.
We welcome you, Maude
and your spirit of willingness.
