latest xp updates cause 3d acceleration problems

I'm running XP Home Service Pack 1 on a 1.8GHz P4 (its a Sony VAIO desktop,
about 3.5 years old) with 512 MB of SDRAM. My graphics card is an Nvidia
TI4800 SE. After updating Windows on Saturday, August 13th, I experienced
problems with all of my games that render with OpenGL or Direct3D
acceleration. They will load and then slow down and start taking up all of my
CPU and memory resources after a few seconds of play.

First I thought this was the graphics driver conflicting with a recent
update of one of the games, so I updated to the most recent version of the
nvidia driver. This did not help, so I rolled back to a previous version that
was very stable. The same problem existed (with both new driver installs I
tried other games as well as the dxdiag tests). Then I ran the dxdiag, it did
not find any problems, but under the D3D tests, the spinning cube spins 100x
faster than it normally did before these updates.

The updates I installed are (KB896727), (KB899588), (KB890830), (KB896423),
(KB893756), (KB899591), and (KB899587). None of their very brief descriptions
say anything about modifying DirectX, does anyone know if any of these would
cause a problem like this? Nothing else on my system has changed since
then... I ran scans with the latest AVG from grisoft and the newest Spybot
S&D 1.4 update to no avail.

Thanks for any help you guys can give me

PS I the games I tried were the latest Half Life: Counter-Strike, Medal of
Honor Allied Assault, and Quake 3 Arena. They all have the same problem, as
if DirectX were causing a memory leak of some kind. After in-game and frozen
every 30 seconds or so the game allows me to resume normal play until it
locks up again, with the frames looking partially rendered and the sound
looping over and over.

I didn't think you could reinstall DirectX?

I would be very uncomfortable doing that without an official program..

I just ran the dx webinstall again and it re-did the direct x 9c setup. Now
Direct 3D doesn't work AT ALL. The test leaves me with these errors:

Direct3D 7 test results: Failure at step 8 (Creating 3D Device): HRESULT =
0x887602eb (error code)
Direct3D 8 test results: Failure at step 8 (Creating 3D Device): HRESULT =
0x8876086a (3D not available)
Direct3D 9 test results: Failure at step 8 (Creating 3D Device): HRESULT =
0x8876086a (3D not available)

I actually realized before that the old drivers I rolled back to were not
directx 9.0c compatible, but then I uninstalled them, installed compatible
ones, and reinstalled DX again. Direct3D still gives me the same errors when
I try to test it, and any 3d rendering apps crash on boot.
