... messing around with hardware! You barely unplug all your peripherals from the pc and plug them back in and it goes through the whole so-called "plug'n play" process, except it doesn't do it properly and stuff that was installed before needs to be installed all over again... and drivers need updating yet again..... Then this no longer works and that's acting funny..... and before you know it you've just spent hours on this great time-saving device called a computer!
At least I think I've put it all back together again.... remains to be seen.
