ATI X1800 XL woes!

[dvothecc]

Hello eveybody, like the title says I am having no luck with my new ATI built X1800 XL that I bought a couple of days ago.

After seeing some reviews and users experience with the card I decided put the X850XT aside for a second system and buy one of these new X1800 XL's.

Once I got it the first thing I did was remove the stock cooler to install a modified cpu cooler and noticed that the memory ic's are 2ns not 1.2/1.4ns like others are reporting. So right of the bat I wasn't too happy but not writting it off just yet. So after installing the card and loading new drivers(5.11 cats), I though i'd do some benching first but half way throught 3dmark05 it locked up Didn't know what to think so I tried running 3dmark05 again thinking it was a one time glitch(maybe) but after resetting my computer and running it again it lockup again WTF?? I could'nt beleive it, my X850XT ran flawlessly just before this card.

So I uninstalled the drivers and reinstalled them and still no luck . I should mention this is all on STOCK settings! No overclocking whatsoever!

So today I decided to format my drive and reinstall windows with only windows updates(SP2), 5.11 cats, 3dmark05, 3dmark03 and other nessesary drivers and thats it. I gained some confidence for the card over night thinking a reformat would do it but no I was wrong same lockups and lost all confidence in the card!

Please could someone help me!! Should I go back to the store and get an exchange? What should I do??
