Hi.

Over the last couple of days I've had a problem with my Mac Pro in that if I allow it to put the displays to sleep that it sort of semi hangs when I move the mouse to wake it up.

The screen remains static and the mouse pointer moves but apart from that, the system appears locked. I'd been downstairs watching a program on my TV, returned to the Mac, moved the mouse and the displays came out of sleep showing the screensaver and the mouse moved but nothing else happened except that. I had to do a hard power-off and back on again.

I'm using an early 2008 8 core 2.8GHz Mac Pro with four hard drives of various sizes and the Nvidia 8800 upgrade. Standard 2Gb RAM.

I think this is the appropriate part of the log:

30/08/2008 21:26:17 kernel NVChannel(GL): Graphics channel exception! status = 0xffff info32 = 0xd = GR: SW Notify Error

I'm a new Mac user, and have only had this system for a couple of weeks. I bought it second hand with the stock video card and immediately replaced it with the Nvidia card but this error looks as though it could be hardware related to me but I don't yet have the mac knowledge to be sure. Is this likely?

Mac Pro (Early 2008), Mac OS X (10.5.4)
