My Geforce6800 stops working when i install the newest forceware drivers

Hi

I have recently changed some of my hardware, and everything was going smoothly untill I came to the point of installing the forceware drivers...
I now have:
Hw:
Epox 4pda5+
Pentium 4 3,0GHz (Northwood)
Club3D Geforce 6800
SB Audigy
2GB "random" RAM (4x512) (I have to simular modules and two different ones)
2 harddrives
Chieftech 360W PSU

Sw:
Windows XP pro (5.1 build 2600)
all the newest drivers for all components

With my old hw (Abit IT7-max2, pentium 4 2,0GHz @ 2,66, the rest same as now (except I only used the two different memory modules, but I have tried the other ones before and I know they work.)) everything worked fine, but now I just get the famous bluescreen of death, saying there is something wrong with NV4_disp.dll.
I have tried a number of different forceware versions, and it seems like the 6x.xx series works stable (I'm now using 67.66). I have som crashes now as well, but I think that's mainly because the games doesn't support drivers that old.

I don't understand what the problem is...
My guess is that either it's the motherboard, the PSU (that it's to little) or that I miraculously have damaged the 3dcard when I moved it... But how come it works with the old drivers?

 

How on earth do I edit my posts? Anyways, I was thinking. It can't be that the card is broken, can it? I mean, if it was broken, how come it works fine with the games that support the old drivers?

(ahhh... I can only edit responses and not the original post... That makes sense... )

 

Problem solved. The PSU was the bad guy...
