Dual G5 Mac Pro Help Black Screen

[leafvillage]

So I have an issue with my Dual G5 Mac, It has 2.5gb ram, I boot fine, I can open up anything and everything. About 5 minuets into use, the background locks up and freezes. I then proceed to move my mouse and then the screen cuts out and goes black all together and the standby light on the monitor hits... Any Ideas on what my problem could be????? I used Istat and the temperature is fine 30 - 45c

Is your G5 going in to sleep? I remember that the June 2004 G5 needed a firmware update to prevent overheat-sleep. This firmware update might only be available on 10.3 or 10.4. Also make sure that the G5 has the clear plastic cover in place over the CPU compartment when you open the case.

What firmware version do you have? Run System Profiler.

Try booting in Safe mode by holding down Shift and see if you can get any further.
