Need help: direct x

Hey,

I just got my new computer last week,
And I installed warcraft 3, it worked fine

Now today I reformatted my hard drives, and installed warcraft 3 again
It says: warcraft 3 was unable to initialize directx. Please ensure you have 8.1 or higher and that your display drivers are current.

Well, when I go to dxdiag, it tells me: Direct-X version: DirectX 10

Thats 8.1 or higher right??

Or is there something wrong with my drivers??

I don't know anything about drivers I just reinstalled my vista and formated my drives, so I don't know what happened


Thanks!!

Install discs are, by nature, outdated, so first use Windows update to bring Vista up to date then update DX here;

Then update your video drivers using either the ATI or Nvidia sites before finally ensuring Warcraft is fully patched and up to date.

Yes, you`ve probably done all this but these are the most common problems, and fixes.

go to device manager and see if there are any error messages. Most likely, you need to go to your mobo manufacturers website and download the onboard sound drivers and ethernet drivers. that is, assuming that you have everything plugged in right and nothing is broken

store bought, I got a lot of disks with it
-one version of windows vista home premium edition
-microsoft works 9.0
-and one apllication and support disc: bundle software not for resale

That are the 3 discs I got

Also, I don't know what brand my motherboard is, I suppose I low-quality one

How do I see it??
