Unless you can do board level microsoldering on iproducts, the computer repair industry is dead. Windows (yes Windows) has gotten so secure that MS has taken the away the bread and butter of the small repair shop. That was, fixing problems caused by malware. In the late '90s and early 2000s the hardware was already pretty good, so rarely failed. Windows95, Windows98, WindowsME and Windows 2000 were all susceptible to malware. Windows 7 changed all that. The malware repairs dried up, computers became too cheap to fix and I switched to renting copiers to hotels for conventions.
