I've got a PowerMac G5 tower that powers up, I hear the fans ramping up, but no display > black screen. I've tried 2 different monitors...same thing.
What could this be? PRAM?
Thanks for any expertise,

Might be time to replace the PRAM Battery, 4 years is close to their lifespan, far less if ever without AC power, & can cause strange startup problems...
See which one your G5 has...

Replaced PRAM battery, but still no display...G5 Tower starts up & fans ramp up, but no display, black screen. Is it the graphics card? Can I swap a graphics card from a G4 tower to my G5 tower? Thanks for any guidance...
Sunny
graphic card is one possibilty.
As to the swap, which exact G5?
Some use AGP cards like G4s, some need PCIe cards, also which g4 card, some or most won't work in a G5 even if yours is AGP.
If you don't know the model, find the Serial# & use it on one of these sites, but don't post the Serial# here...
