Hi everyone, I'm looking for some help with my Mac Pro 5.1 (originally 4.1 but flashed to 5.1). I've tried searching but can't find a solution. My issue is that over the past few months I've noticed a pattern wherein either in the morning or at random times during the day I'll notice that the Mac looks asleep (ebbing white power light) but I'll hear the fans running and the disks spinning. If I push the Apple Pro keyboard keys or click the Magic mouse nothing happens. I can't seem to make the screen wake. It continually registers as not receiving any input from the tower and then I'm stuck. I need to use it for work purposes but the only way to make it useable is to force reboot by holding the power button. Initially I would notice this every few days but it's becoming more frequent and I really don't like the idea of having to hard rest my Mac. I have backups/redundancy measures in place but this is not normal. Does anyone have suggestions on how I can troubleshoot? I tried resetting the PRAM a few weeks back and the problem seemed to go away only to now return with a vengeance.
