FX 4500 + Asus P5W DH-D issues

[Stibhaus]

Hey everyone, I have a major problem with my new PC build.
I have put together a new machine with the following specs'

Dual core 6600 4mb
Asus P5W DH deluxe
Gskill 6400 2gig ram
Seagate Sata 2 320G
PNY/Nvidia Quadro FX 4500
Antec 400W Truepower
Windows XP pro

The machine is ok until I try to install the graphics driver. Then it either shuts down during installation... in the last bit, or it has issues when starting up after a shutdown.
This is a bit odd because if I do a restart its fine. Its only when I shut down, then start the machine. eg if I shut down go to be and turn it on the next morning.
I turn the machine on, the Asus splash screen has some white dots usually in grids across the graphic, then the Windows XP splash screen has Blue dots in grids across some part of it, then when I log in it crashes soon after it has started up.
If I restart its still all bad. If I restart with last known good configuration... no good, Restore... same story. The only way I can get it running again is change the card to the other PCI-E slot and start up, sometimes change it back and forward a few times. Uninstall drivers reinstall etc etc....
I'm using the drivers from the Nvidia web site and have tried others too.
The ones I have tried are...
82.62 Forceware English and international versions.
91.85 Quadro
101.89 Forceware
All for XP of course.
I installed Vista and tried the Vista drivers.... no good either.

If anyone can help me out here it would be a gret help.

Thanks,
Stibhaus

Make sure your bios is up to date as it fixes lots of issues(2004 is the newest). Also your PSU seems a bit on the weak side. Can you test the video card is another PC?

[Stibhaus]

My Bios is up to date, and this is the only PCI-E machine I have. Others are AMD with AGP.
I was going to borrow a different graphics card to try in it. Is there a chance that this Motherboard is not compatible with the Quadro card ?
Is there anyone out there with a similar set - up ?

Cheers,

Ben

Another thing you can do is disable PegLink in the bios. I think it OCs the video card and can cause problems with some(I have to run it on slow too). Go in to the bios and try running the card with PEGLink on the "Slow" setting; it's worth a shot imho

[Stibhaus]

Thanks, I'll give this a go tomorrow evening as I have a project due tomorrow and cannot risk any downtime with the machine until then.
Would this have any effect on the performance of the graphics card ?

Tried the peglink option with no joy.
Same old story unfortunately.
Its about time to buy more stuff just so I can try to solve the problem. Expensive way to troubleshoot...
