There have been some issues with new PCIexpress x16 v2.1 in older v1.x motherboards can you post all your specs so we can see if that is a possible problem. Then again there is always a chance that the card is DOA.
Had it boxed up to return...I've tried everything 10x, and keep getting the same errors and mis-boots(freezing on start-up, blank screen freeze, and my personal fav...No signal/no display!) as everyone else on here.
...and yes its an older (2007) motherboard.
Here are my specs...
gateway GM5661E (acpi x86)
windows 7/dx 6
500g wd ata 7200 rpm/ntfs
intel core 2 duo/2200 mhz/800 mhz front/200 mhz extrn
3 gb ddr2
board-ecs 945g-nm uatx
1 pci xp x1
1 pci xp x16
2 convent pci
Integrated Intel 82945g exp chip (drivers 9/09)/realtek HD Audio
avermedia ntsc/atsc tv tuner card (uninstalled. needed both bays for 5670)
card is oem ati hd radeon 5670 dx 11 / 1 GB DDR5/manu biostar/sigma gate/ box says nvidia gforce, but card is ATI
Any help would be greatly appreciated or it goes home 2morrow!
Thanks in advance!
