Really sorry if this is actually how it's supposed to be on a PCI-E card (been on agp forever!) but I'm troubleshooting a new build and my motherboard (asus p7p55d pro ( w/ core i5)) is flashing its little VGA diagnostic light at me while I'm getting nothing on the monitor.
And yes I've connected the pci-e power (from a nice 650 psu from corsair)
OMG - I have no idea how on earth it made any difference - but I read some rubbish online somewhere about trying the different ram slots - which didn't work and suggested to me to press the 'memOK' button (a default failsafe where it tries different ram timings etc... which also didn't work... but then when I put the RAM back in the original slots and just gave everything a good shove it booted - the bios came up with options to recover settings as after a failed boot, but whatever kicked it into action - it's working!
Thanks so much for you help and suggestions, I wouldn't have pursued it if you hadn't told me the card was actually normal!
