May have an idea

I think I know what is happing with my 5770.
I have an older A8R32-MVP DELUXE motherboard what I believe is that the motherboard is not recognizing the new 5770 video card.
At that time about 4 years ago a one gig of memory on a video card was not thought of yet, well not for the every day joe.
So I thought all I need to do is update my bios and chipset drivers so I did that .
The bad thing is that the last update for my morther board was in 2007.
So I think I am a victim of old hardware blues =(
I think my only corse of action is to update my motherboard.
What do you all think ? any imput would be appreciated.

I know of other motherboards that have this specific issue as well. You should go ahead and try to upgrade the motherboard though, assuming you have went through proper diagnostics on your HD5770.

I am running a 850 watt Thermaltake power supply and a AMD ATHALON 64 4000 cpu and 2 gigs of corsair ddr pc 3200.
The operating system is xp 64 bit.
Well I think you found my problem with the other persons post looks like a new motherboard for me thanks everyone for the help[/b].
