XP workstation screen goes black after login as desktop loads

We have an XP Pro workstation which has a problem with the screen going black after login, as the desktop loads. The PC is still active, and we can eject the CD drawer.
When we start in safe mode with networking, the workstation operates perfectly.
We have used MSCONFIG to dissable all but Microsoft items, but the problem remains.
If we leave it at the Ctr-Alt-Del logon box, it stays on constantly.
I have removed the video driver, and restarted, but although it seems to stay on a little longer (may have been just a coincidence) the same problem happens.
We are using AVG v8.5 and have fully updated signatures, but a scan shows nothing.
Does anyone have any good ideas, as it is driving me mad!
Many thanks.

Is there a dual port video card?  I sometimes see this if the card is setup to run on the port that the monitor is not plugged into.  Could also be a video card hardware problem.  Try switching it out with another card and see if the problem remains.  

Good luck!

No it is a single analogue video out. A standard Lenovo Thinkcentre.
It works fine in safe mode, but when we start up with the Intel 946gz Express Chipset driver uninstalled, ie using the standard Microsoft VGA driver, the problem remains. Should not give us the same config as when starting in safe mode?
Many thanks.

I still say it's likely the video card.  If you have the same problem with another card you will know it's a configuration problem or other problem.  (also maybe try a different monitor in case the resolution is what's causing it to black out).

I'd replace the video card.  Just borrow one from another workstation to test it

I have tried s different display but the problem remains. The problem is that nearly all of the workstations these days have the graphics card as an integral part of the motherboard, so I don't have one to test with. If you feel that it is the video card, I will have to buy one.

Big computer shops have them for $100.  You can return it if that's not hte problem most likely.  Otherwise go to newegg.com and get one for a fraction of the cost.  That's where I buy all my parts...

sorry for the delay. This was in fact the problem. We replaced the video card (well we added another actually, as the original was on board), and this did resolve the issue.
Many thanks.
