FX5600 TD128 sets monitor into standby

Question

Hi all
I searched the existing threads and found some similiar issues but nothing that was exactly the same.
I formatted my drive and installed Xp with SP1a. Tried to install det. 53 from Nvidia and the monitor went into standby and didn't come on again. Installed 44 which came with the MSI FX5600 TD128 which worked. Then I installed 53 and XP was happy. Loaded Q3 and when I tried to run it the monitor went into standby.
Found a link on the net about disabling Enable Write Combining in driver properties and this sorted out the Q3 problems. Then this past weekend I was surfing the net and the monitor switched off. I then tried UT2004 demo and the game loaded but the minute I click on the settings menu the monitor hung again.
I got fedup and installed 2000 again. Q3, UT2004 and COD all run fine and my monitor isn't hanging.
What could be causing the vga/monitor problem in XP? Here are my system specs( at work at the moment so can't supply the PSU voltage):
AMD 900 Thunderbird
Asus A7V Pro KT133
512Mb PC133
20Gb Fujitsu 7200rpm
SBLive 5.1 DE
Accton 10/100
56K Modem
MSI FX5600 TD128
Viewsonic E70 17"
Sparkle 300w PSU
Thanks

I appear to have a similar problem with a FX5600 VTDR128  .  I have the latest updates to XP, main board bios and NVIDIA drivers loaded  (the problem was not any worse under the previous versions of the drivers).
Periodically, the screen goes blank. The blanking occurs in 3 forms, (1) things go blank for 2-3 seconds and then comes back, (2) the screen looses the signal entirely and the system continues to run but I have to reset and reboot; and (3) occasionally the whole system appears to be taken down by this process and reboots.
Thinking that it could be a power supply issue, I installed an ANTEC 550 true power supply (which is great  ) but it did not solve the problem.  I have also tried a number of voltage settings for both video and memory but they did not seem to change things either.
Any further suggestions would be appreciated
