There is a little computer shop close to where I live. It can't compete with internet pricing for major pieces of hardware but it is a useful source of consumables. He does a pretty good deal on printer ink and on several occasions the ability to nip round the corner and buy a patch cable has gotten me out of a hole.
I was in there this morning buying ink. A customer in front of me was inquiring about a video card upgrade.
"Can that be done on the spot if I drop the computer in" he asked
Unfortunately the young lady behind the counter was not a technician and "the engineer" as she called him would not be back for a while.
"It has to be booked in It could take a few days" was her reply.
The customer asked
"How hard is it to upgrade a video card? Do you think I could do it myself?"
The assistant was honest enough to admit she didn't know and recommended that he leave the computer with them.
Recognising a potential fellow gamer I ached to interject.
"Its easy" I could have shouted "I have changed dozens of video cards"
I could have given him a five minute crash course in swapping video cards. If he lived nearby I could even do it for him.
But then I thought what if ...
What if he card he has bought in ignorance isn't compatible with his machine? What if it has the wrong interface or is too long for the case? What if his power supply doesn't have the six pin adapter needed? What if there isn't a driver available for his obscure operating system? And will I really be able to prevent myself from blurting out that the Geforce4mx he just paid €150 is not exactly the bee's knees of graphics cards despite the fancy box and that he really should have gotten a BFG9000 for the same money. An what happens the first time he installs a game that doesn't work properly because it is incompatible with Nvidia or ATI cards and the guy assumes its my fault because I installed it wrong.
Regretfully I admitted to myself that I didn't want the hassle. Thats what computer shops charge installation fees for. Plus I didn't really want to do my local shop out of the few euro they would charge him for the install.
