My 2008 MacBook Pro has been acting weird since the recent lion update. Very frequently (up to 10 times a day) I can't wake the computer up. The screen stays black and I get the SBBOD and I'm forced to do a hard reset. It seemed like it was related to the bluetooth because it was happening much more often when turned on but now it happens with it off as well. I've also noticed that the volume buttons are not working as smooth. For example, sometimes it won't go lower than 3 bars and it seems like the number of times I hit the volume up or down doesn't seem right. For example, I'll hit the down 2 times to move down one bar once and then have to hit the down 5 times do move down one bar. Also, I have been wanting to reset my PRAM but it doesn't seem to want to reset. I don't get the two audible tones but instead it restarts and restarts over and over again as long as I have the Option+Command+P+R pressed. I've also reset the SMC and nothing. (I have reset the PRAM in the past so I am familiar what it's supposed to sound like). I'm thinking of going back to Snow Leopard and see if this continues but I'm concerned that I can't reset the PRAM. (Also, I have confirmed that I do not have a Firmware Password). Any suggestions? Or ideas what is happening?
