Mac wont boot
Hello,
Recently my Mac Pro started to have problems. It would run very slow and freeze up for a few moments but would recover. After awhile it then started to give me another problem. While I was using it, the monitor would start to become distorted and it started to get to the point that the monitor would go to complete distortion and the only way to recover the picture would be to put the mac to sleep and awaken it. I shut it down the other night and ever since then I have not been able to get it to boot back up. It will turn on, I will hear the drive start up and continue to spin but it does not make startup sound and the monitor does not turn on. I have done some searches and I have come across that this indicates one of several problems:
1. Drive is corrupted
2. Bad Video Card
3. Motherboard is bad
I was attempting to boot from my install CD to run some tests on the Disk to see if it was bad however it wont even boot from the disk.
Any suggestions on what could be causing this?
Mac Pro, Mac OS X (10.6.8)
