A question mark shows up when Mac is booting up.When there's something wrong on PRAM/NVRAM, Mac will behave abnormally with following symptoms : SMC (System Management Controller) is in charge of Intel-based Mac, playing an important role on the physical parts of the computer such as the thermal and power management, sleep and wake, battery charging, LED indicators etc. Moreover, NVRAM reset is faster and safer. And nowadays most of Mac computers use NVRAM instead of PRAM because sometimes PRAM will go wrong for instability and you have to restore and fix it. NVRAM (nonvolatile random-access memory) offers almost the same service PRAM for users to store certain system settings. With PRAM, you don't need to worry that data will be erased regardless if Mac is turning on or off. PRAM (Parameter Random Access Memory) is a non-volatile random access memory which is used to store system settings on Mac, including sound volume, display resolution, startup disk selection, time zone, and recent kernel panic information.

That said, Titaniums unfortunately are not holding up well with age, and I rarely get one that doesn't have some sort of motherboard flakiness, or at least a bad RAM slot.Īlso, could the "ripping" sound be the sound of a blown speaker? Resetting the PMU should make the computer produce a solid tone, so if that tone sounds distorted or rough, that could be indication of a blown speaker. I've come across many Titaniums which I was told were dead, only to find that they had been tested with PC-100 RAM, and replacing it with PC-133 made them come alive again. I believe they also require PC-133 RAM, as opposed to PC-100, which can be confusing, because both types fit in the same slot, although PC-100 will not work (or I've never seen it work, anyway) in a Titanium. One thing with Titaniums is that they use "G3 RAM", with the notch more toward the middle, instead of "G4 RAM" with the notch more toward the end, like Aluminum PowerBooks. I'd also reset the PMU while you're at it. Hi! Three beeps generally has to do with a RAM issue, so I'd try known-good RAM, and also test your memory slots one at a time by putting a module in one slot only, powering on, and then in the other slot only, powering on, and resetting the PRAM immediately before powering up each time.
