Alert! error initializing PCI express NIC bridge... help please

I keep getting this error when i boot up to windows. When i hit f1 it goes to windows and everything is fine.

 

I called dell and tey told me to update my bios to ao6. I still get the error then they told me to use the resource cd to see if there where any errors. No errors.

 

 

I did have to replace my nic card.. Because the onboard one died somehow. I even disabled it in bios still get this error....

 

I even tested my video card and still get this error

 

 

Is it the slot holding my video card? Is that why i'm getting this error?

 

I even cleard the  nvram

 

Even did a flat install of xp nothing still getting this error and dell says my 1 year warrenty don't cover this?

 

I f someone on this forum can please help me
