I recently had a small USB issue, so I reset my PRAM which fixed it. Now every time I boot the PRAM will reset itself. This particularly annoying because: 1) It takes longer to boot as it restarts again and again (sometimes 3-4 times). 2) I have the boot volume set to 0 and when the PRAM is reset it will go back to default which isn't fun [and it loud]. 3) I have verbose mode on and a PRAM reset removes that as well, so I need to do the 2-finger combo [which on the bluetooth keyboard doesn't work half the time]. I can't seem to fix it. I've done all the usual things (ie: manual PRAM reset with 4-finger combo, SMC reset, reseating hardware, disconnection hardware) and I've also gone ahead and installed OS X on a new volume for testing. Nothing is working and this getting a little frustrating. I try not to restart my computer, but recently I've needed to it a couple times. Apple Support doesn't know what to do and they're reluctant to send a on-site tech because they're not sure what the issue is. They want me to take my computer to the Apple Store, but (1) I don't have a car, (2) it's windy and snowing like crazy outside so there is no way I'm walking a mile to the Apple Store carrying the Mac Pro by hand, and (3) even if it was sunny outside my computer weighs a lot. Anyone know what's going on here? The computer passes all hardware tests and disk scans reveal no bad sectors.
