Hi folks - I posted this problem as part of a number of problems under the PowerPC section but if it's alright I'll raise the profile of one of the elements in this section? I bought a refurbished quad-core G5 from eBay two weeks ago; on arrival none of my older monitors would fit the factory-fitted PCI-E graphics card (it's DVI while my Studio display is ADC and my LCD monitor is VGA) so I used an adaptor from the VGA monitor lead to the DVI socket but received no signal at the monitor. I thought maybe it was the fault of the adaptor so I then purchased another monitor with DVI connections but this also gets no signal from the G5 - only the message "no input signal is being received". I've checked the graphics card is properly seated and that nothing internal has been dislodged in transit. Anything else I should look for, or any tests I can run? If I require another graphics card eventually what should I go for?
