MSI NX8500GT-TD256E Driver problems

Question

Hi,
I have a PCI express MSI NX8500GT-TD256E video card in a MSI K9AGM3-F motherboard. It was working prior to having to re-install xp (but on board sound wasn't), but after reinstalling xp, when I install the video card drivers, the screen becomes unreadable, just pixelated colours!
Without the drivers installed, just the xp vga drivers, the screen works good -32 bit full colour at 1024 - 768, but as soon as I install the Drivers - unviewable! I have downloaded the latest drivers from the MSI web site and I have even tried different drivers with same result, soon as I reboot - crap!
The video is ok without drivers installed, so I take it he card is working ok, Power supply 450W, and 18A at 12V, so that's ok,
but without the drivers installed can't use duel screen, new games etc. and sys info says video adapter not installed. (After reinstalling sound drivers sound working good.)
It is verry frustrating. Any suggestions??
Just a follow up. I unistalled driver, ran Driver Sweeper then NFR just to make sure I uninstalled driver, then installed driver version 1819. Still same result. If I press F8 and boot in VGA mode, I can see all the info on Video card, and the NVIDIA tabs are in display settings, but if I change the resolution the same results - unviewable screen with block colours like the old CGA colours.   With no driver installed I can get 1280 by 1024 full colour 32 bits.
Anyone with any Ideas, please help.

It looks like drivers mess.
Do a >>Clear CMOS Guide<< {With power cord removed}
I suggest you again new fresh install, then install chipset drivers http://global.msi.com.tw/index.php?func=driverfile&dno=2427&i=0
Followed by VGA Drivers ==> http://www.nvidia.com/object/winxp_175.16_whql.html
If no change test VGA in another machine
