Sorry I want to ask, I hv a Sis 650 Rev 00 chipset, name Sis 650_651_M650_740. Originally I hv Direct 3D 9+ but after I reformat my disk I now only capable to Direct 3D 8+. Can I change it back to Direct 3D 9+?

You can download Direct3D included in the DirectX SDK >> (http://www.microsoft.com/downloads/details.aspx?familyid=ec97a1fb-4305-4758-b7c4-5a12b3fe8ec2&displaylang=en)

Here you go:
Download details: DirectX 9.0c End-User Runtime (http://www.microsoft.com/downloads/details.aspx?FamilyID=0A9B6820-BFBB-4799-9908-D418CDEAC197&displaylang=en)

Well... this site is for downloading directX 9.0c. My PC already got it...

Did you try the DirectX SDK download that includes Direct3D?

Then go with what benn's link. DirectX 9.0c contains all the DirectX files including 3D. I found it odd that you would lose only a portion of thise files so I thought it safer to re-install all of DirectX.

Well... it maybe useful but I can't take this step because I don't have a original XP version... hehehe

Then that pretty much closes this thread.

Ok... maybe re-install directX 9.0c may fix the problem...

Thx for all your help... I will inform you guys when it works...

I have a DirectX 9.0c cd. When I installed, I check it at DirectX Diagonastic Tool--Display but it still show :Hardware accelerated Direct3D 9+ is not available because the display driver does not support it. You may be able to get a newer driver from the hardware manufacturer. When I test Direct3D interface it say:Direct3D 9 test results: Display driver does not support API (DDI version too low)

It is strange since it can support Direct3D 9+ before...

The closing thread part wwas related to your admitting you have a pirated OS.
