Hi folks, I have a 2009 Quad Mac Pro. It's been totally great until maybe two weeks ago. I could no longer use the keyboard before the Apple logo upon boot. As in, can't reset PRAM, can't choose boot (bootcamp/OSX) etc. In windows, every key I press mutes/unmutes the volume, until I uncheck/check the "All F buttons as standard functions" button. Even then, typing brings up random error pings and a letter or two will be missing. In OSX, the Volume indicator (which has a cross through it as I use an external card) flashes up on to the screen randomly. I thought it might just be the keyboard going, but in the last couple of days, my mouse, a Logitech MX revolution has started to get stuck for a second or so when moving at random intervals. It's usable and more a nuisance, but it raised my suspicions. I've also had a harddrive die, which has been ticking since 2006. I don't know if it's all just coincidences, but I'd like to sort it out and know if my Logic board is going to go..I have stuff to score and if so need to sort out an alternate workstation! any advice would be appreciated.
