Hi all just changing from a 8800gt card to a Powercolor 1GB 5770. Uninstalled the nvidia drivers, turned off pc, inserted the 5770 and switched on pc and not getting any display.

Stick the 8800gt back in and i get a display. Help please

Only thing I can think off is the external power connected ok to the card.

Yeah its connected fine. Fan on the card spins up. Not sure if it might be a motherboard bios issue now

i had the same problem with a 5870 that i bought from ocuk, i put my gtx295 back in and it booted fine so after a few tries i decided to rma the card back, they tested it tho and said it worked fine for them so i have no idea what the cause was

Did you stick with the gtx or have you tried an ati card again? I have just found that the 5770 using pci-e 2.1 where as my board does pci-e 2.0. Could that be the issue?

Well i dont know what was wrong but i got it working now. Upped the GPU clock to 900Mhz and the Memory clock to 1350Mhz with no bother at all
