Mac Pro 2009 turns on, fans work, but No display
I have a 2009 Mac Pro which worked well for a few months. Then I chose to take it apart to clean it out and add a HDD and when I put it all back together, it wouldn't send a signal to my monitor.
The fans all run normally, except the fans on the GPU (original NVIDIA 120 GT) which are louder than usual.
I connected the gpu to my monitor using a mini diplayport to hdmi as I usually do, but get no signal on the monitor.
I have tried:
To reset PRAM and BIOS
Change BR2032 battery
New graphic card (ATI radeon 5770)
Reset files inside of SSD and HDD
Connect to another monitor
I don't know what else to try and would really appreciate any suggestions and advice!!
Thank you in advance
Ist dies eine gute Frage?
