Major Direct3D glitches on GeForce 4 MX440

I am running Windows 2000 on Pentium II 450 MHz, 128 MB RAM. My graphic card is GeForce 4 MX440 with AGP 8x and 128 MB vRAM. I am using the latest drivers.

I have recently started to experience graphical glitches in computer games: certain objects not appearing on screen, major screen redraw(?) problems. I have attached a screenshot from Half-Life as an example. The walls are distorted and there should be a person model on screen, but it is not visible. The problem looks similar in other games: distorted in-game screens, missing items in graphic-heavy menus, e.t.c.

I have managed to trace down the problem to Direct3D. OpenGL renders work just fine.

The actions I have taken to try to fix the problem:
- reinstalling nvidia's Forceware drivers - did not solve the issue
- reinstalling DirectX 9.0c - did not solve the issue
- lowering hardware acceleration to the point where it disables all Direct3D features - makes the image display pretty much correct, but most DirectX dependant games refuse to run due to lack of required features

Any advice on this matter would be greatly appreciated.
