DirectX downgrade on WinXP, possible or not?

[DutchMaster]

Hi there.

I finally got some time to tweak up the system a bit.

I was running winXP with DirectX 8.1 and thought it was necessary for the performance to update to 9.0b.

BAD IDEA, my system either gives BSOD or just reboots.
Even when the system is idle.
No information is logged in eventviewer. But problems started after installing the latest DirectX.

So, is there a way to roll back to version 8.1 without reinstalling winXP? There is no install feature, but there must be some software to remove directX components?

Any help is welcome, thanks

BTW:
sys specs:
SIS 746FX 1.17 AGP
Abit GF 440MX card
winXP SP1

Have you tried safe mode, and system restore, to before the DX 9 was installed.

Also, I think SP1 will make your windows DX9 compatable.

You can't uninstall DX9.
Same as all DX versions since 7.
Sorry.
You might try a repair install before a full reinstall though.
and remember to unencrypt any files you may have encrypted with the EFS. You won't be able to do it afterwards.

Thanks
I was afraid I couldn't uninstall DirectX, but possibly there is some kind of brutal remove utility.

I tried a sys restore however, for whatever reason, there is no date selectable before I installed DX 9.0b

It took some time digging and googling but found a batch utility to do the trick:

DirectX 9 Uninstaller for XP / .NET

For future reference, it can be downloaded here:

It works, DXDIAG shows 8.1 now.
Now hopefully the problem is fixed....
