Not sure what the "Manufacturer/Model: Microsoft/Windows XP Inside Out" means but I couldn't find a way around it. I am using XP Home on a homebrew machine that is a little long in the tooth but works OK - most of the time. The video adapter is an NVIDIA GeForce FX 5200 running two VDUs, on on the analogue and one on the digital port, which has worked fine for several years. My current problem is that when I click the "Close" or "minimise" buttons, windows are very slow to close or to disappear from the desktop. When I click the close button the window closes in jerky steps over about a second. When I click the minimise button the visual effect of the window shrinking onto the toolbar happens in a flash, but the actual window again closes slowly in jerky steps over about a second. I think this started happening about the time I installed a .NET framework upgrade.

Does the computer work fine other than that? What happens when you revert the .NET upgrade? WinSimple Software CompTIA A+ Certified

Yes everything works fine apart from the slow redraw. In fact I did a bit more experimenting and I found that if I have an open window and drag it around the desktop, the window itself moves just as quick as I move the mouse, but the desktop background is slow to redraw behind the moving window. The moving window leaves a white trail which is only slowly overdrawn or filled in with the normal desktop pattern. The really odd thing is that this only happens over the desktop background - if I drag the window over another open window there is no slow redraw of the other window, it's only if the window I am dragging overlaps onto the desktop that the slow redraw of the desktop takes place, the other window redraws underneath as fast as I move the dragged window. I didn't try reverting the .NET upgrade because I am not sure how to do it, and when I Googled for problems with the .NET upgrade I didn't find anything. But I am willing to give it a go.

Your graphics card is in distress. You might try to update the driver and if that doesn't work revert to an older driver. Is this being seen as only at desktop or does it do it on line mostly. I have seen this also caused by memory gone bad as well.

Try system restore, Netframework might is in the add/remove programs UK MP's are thieving scumbags. EU members are worse.

I have tried uninstalling the graphics card in Device Manager then rebooting and reinstalling it using the latest drivers available from NVIDIA but it's still the same. The slow redraw is of the desktop background only, it doesn't affect the content of windows whether on or off-line. I was going to try a System Restore but I found that for some reason it was disabled and I have no restore point to go back to. I have no idea why this should be - I have never disabled System Restore.
