Switched to backup BIOS, same problem. Do you think failed motherboard?

Hello Pilgrim. Thank you also for your suggestions. Tried disconnecting main power and 30 second test first with no result. Then per your suggestion, disconnected everything to minimum config. and still have same issue. Power on, fans spin up, one beep, then power down and reboot, whole...

Thank you for the suggestion. I replaced the CR2032 battery with a new one, but same problem. Press power button, fans kick on, one beep, then within 3 seconds reboot and repeat. Also tried holding Command+Alt+P+R, pressing power while holding down either shift or C keys, nothing so far gets...

Hello everyone, I just returned from a two month trip overseas. Before I left I unplugged the surge protector/computer just to be double sure nothing happened while I was away. I live in the Philippines, not the best electrical grid in the world. When i returned today, I plugged the surge...

I would like to thank you as well cmn699. I had this exact same problem today, followed your instructions and am now restoring my files from a CCC backup I did right before install of Sierra. It is great that folks like you are available to help out those of us with less experience.

Rebooted and no problems at login but Presonus blinking and not connected. Rebooted again and no freezing and Presonus connected. I have a feeling at this point it may be as simple as a bad firewire cable. If you have any other thoughts let me know, but thank you very much for pointing me in...

Download and installed Universal Control from Presonus with Mavericks compatibility. Rebooted after install and tried -f, went to apple splash screen and text appeared with panic (cpu 1 caller 0xfffff80006681a8) Rebooted without the -f, login, no freezing and presonus is working.

Going to Presonus site now to download updated driver with Mavericks compatibility and will uninstall/reinstall Firestudio and see what that does.

Here is what I did: 1. Went to system preferences, but nothing related to Presonus or Firewire there 2. Shut down computer 3. Removed Firewire cable from card, kept card in computer 4. Restart with -f (all OK except obviously no Presonus working) 5. Restart with no -f, all OK 6. Shut down...

Thank you for your reply. The only updates I've done recently was iTunes and Safari. I tried booting with -s, got to a root command prompt, typed exit, got to login screen, typed password, and system froze. I rebooted with the -f, login, and now the firestudio is connected (solid blue light...

I posted another thread last week and user Violet Dragon attempted to help me, but to no avail. I built my system two years ago using iBoot, Multibeast following instructions on the tonymac site and had a fully functioning system for the last two years. Suddenly last week, after typing my...

I really appreciate that you are trying to help me, but your answers are so brief I do not understand. Why did system work fine for two years and problem now? What is in the file I uploaded that causes you to believe that power management is the reason my system is freezing after login? Why...

As I mentioned, I did not use Clover, I used Multibeast. The guide you referred me to requires Clover. Since the guide states that power management is not required, and my system worked fine for 2 years, can you tell me why I would require power management now? What is it that causes you to...

I followed your link. I am a beginner as I mentioned. If I follow those instructions and download the file (which I just did in Terminal window), then change the permissions by cutting and pasting the command in the Terminal window, then I will be finished? Or is there much more to it? Are...

I saved another copy and attached it. Thank you again for your help. I am using IORegistryExplorer Version 3.0.2 (14). FYI, just booted computer today and froze first time right after login. Restarted and froze again, this time few seconds later after login. Restarted again and used -f...
