| Thanks for all the responses. Tui, Good luck with your problem, hope everything works out for you. I would check to see if your cards and ram are seated fully in their respective slots, sounds like a short or connection problem. I once found a computer to have a motherboard grounding out because of the case. I doubt that would be the the problem with a mac. They are designed well. On to my machine, I thought the ram first, however there are a few more variables before I can suspect that. I have UAD cards installed now, but the problem was happening before the UAD cards were installed. I also thought bad Power Supply, or bad switch on the physical button. My mac pro decided to power on today, so I left it on all day and I will take it in tomorrow and use that 3 year warranty I have. Today, I unplugged it from the back of the monster power pro 3500 to the two unswitched plugs on front. I am wondering when I turn on the MP3500 if it sends a surge to my mac pro, and the power supply on the mac protects itself by not powering on? I am still curious if it could be my MP 3500 causing this problem. I am still doing some research and testing different outlets, including a different power cable to prove that the monster may be the problem. I have built many pc's over the years, and I have had a few minor problems here and there...mostly driver, conflicting software issues, or bad hardware. I am not in anyway insinuating that mac is a bad computer, nor stating that pc is better than mac. I have used both and I like both equally. I posted to see if anyone else was having these problems. The first day I incorporated this mac pro into the studio setup, I noticed the power/stability of this machine in that the new macs are robust and screaming fast!!!! I haven't built a new pc yet because I am going with a new laptop for my location gigs. Plans for a new desktop pc build will definitely be in the future though. Thanks again everyone for contributing. |
