Can someone please let me know if the following is a simple fix or is gonna cost me the earth??
My Mac Pro sometimes refuses to power up. The front button gives no response - sometimes for a couple of days, sometimes for a couple of hours.
If the Mac goes to SLEEP then upon waking it makes a really loud fan noise and despite being powered up the monitor will stay black and it's unresponsive. I've set it to never sleep as a result.
In the last few days it has been 'freezing' randomly. Once on screen saver (the images that usually animate and dissolve just froze) or while using text edit. Both time I had to pull power from the tower. Ouch.
Any clues/tips/help greatly appreciated.
Many thanks.
