MacPro3,1 (2008) gets a blinking white light but sometimes does start up, what's going on?
Hello,
I've got a MacPro3,1 (2008 model) that up until 3 days ago was working fine.
I haven't moved the Mac from its physical location, haven't installed any new hardware or even connected any new devices to it but upon restarting I now get a blinking white LED light and no video.
So I looked around the forums and most results pointed towards bad ram, since I've got 16GB of ram 8 dimms 2GB each it took a while to reseat them all properly but even after reseating them I still get the same issue. A calmly blinking white LED light of the power button (1sec interval).
The odd thing is that none of the riser cards show any of the usual red lights that would turn on if the ram was faulty/not set properly, and then once I force the computer to turn off holding the power button and turn it on again, sometimes the Mac will start up again (not all the time, it may take 3-5 tries).
Does anyone have a clue on why this would always happen when restarting/starting the Mac but that it would then take a force shutdown and a few tries and then starts up again?
Also, during the startup (when it does startup) the Mac won't accept any keyboard input (to try bring up the hardware test or go into the boot manager or even resetting the PRAM by holding ALT+SHIFT+R+P is not possible).
