G5 intermittent blank screen on boot up

I have a G5 that has started intermittently booting up with a totally blank screen - not blue, no video at all. Sometimes on reboot or after resetting the PRAM it works again...

Any suggestions?
Many thanks

Have you tried other monitors?
Does it boot all the way even with a blank screen? You can try turning on file sharing when you get a working screen then wait the normal boot time to access your G5 over a network with another computer.

It could just be a failing video card. Do you have the hardware diagnostics CD? When you do get video on boot you can try running tests with that.

Beyond that the only other way I can see testing the video card is getting a cheap replacement off ebay and trying that out, get a PCI one for testing it should be cheaper than any AGP for G5's. It would certainly be cheaper than a technician.
