I have a 2008 Mac Pro Tower that all of a sudden wants to freeze up, besides mouse movement. Upon restarting with the power button, it gives me 5 boot up chimes, and never boots up. Only gives me a black screen. It then repeats itself over and over again. Any suggestions?
Thanks

Problem solved...maybe. I unplugged everything from the tower, waited about 10 minutes, pulled some people into my office to put it on the spot, plugged it all back in and voila! It made me out to be a liar. I hate when it does that. BUT, could this be something that is going out on this motherboard?

It could be memory-related. In the case of "not enough working RAM to start up" BOTH the power light blinking and a set of three tones could occur.
In the iMac and MacBook, problems with memory are detected by hearing the three tones. In the Mac Pro silver tower, the tones seldom sound, and the blinking power light is more often used to detect this problem.
The Mac Pro uses Error Correcting Code memory, so you will not see this problem fester. Minor problems are corrected by Hardware on-the-fly, and major problems cause bad module slots to be declared "empty" if caught early, and cause a distinctive kernel panic, machine check if caught later.
