It's so long since I first picked up a spanner (basically out of necessity) that I've often found it hard to relate to the (perfectly reasonable) trepidation felt by mechanical newbies when faced with fairly basic maintenance or repair tasks. Or, particularly, with the euphoria felt when it all goes to plan and the repair is successful. Well, I've just put myself in your shoes in an area where I'm desperately uncomfortable and ignorant, by opening up my computer and installing a cheapo Ebay firewire card. And it worked. And my PC hasn't died yet as a result . I'm just ridiculously chuffed with myself. It's quite laughable really. Of course, if anything whatsoever had not gone according to plan, I'd have been utterly stuffed. Still, I figured that I could always then take it to someone competent and it wouldn't cost me significantly more than if I'd got them to do the installation in the first place. As it is, I've saved a few bucks and gained this wonderful (and grossly out of proportion) sense of satisfaction :grin: .
