[happy17292]

i am having problem with Direct X9c , when i try to install it on my pc it installs and shows finish. when i check, direct X 9b is shown.
i have updated my display drivers, even formatted and reinstalled XP.
[Direct X 9c was working fine few months ago. before i formatted and installed XP as it was corrupted]. i have also tried this with Win98Se but it also shows Dx9b.
i have latest direct X from microsoft.

my PC:
Celeron D 2.4GHz
120GB HDDs
intergrated S3 Pro Savage DDR graphics 32MB
480MB RAM.

PLEASE dont suggest me to buy a new Graphics card, processor or motherboard.
since
DirectX 9c Was warking fine earlier in this computer

if you want cheap dx10 then go for geforce Palit 9600GT or 8600GT.
If you want midrange then:- Palit ATI HD4670

I think you need to download DX9c again or get it from Digit CD.
