Post a DXDiag please, so we can see your specs (tutorial in my signature)

Sounds like an out of date graphics driver. Try updating that and see if it helps.

this is my dxdiag

Your graphics card is not supported on Windows 8, downgrade to Windows 7, get a new graphics card or use a different computer.

I fixed it!

Simply go to Device Manger, and update your Microsoft Basic Display Adapter! Make sure you choose the option that says search the internet and your computer.

I tried it. But not work on me

Before what tails said above, you could try installing drivers anyway (likely from here: https://downloadcenter.intel.com/product/81517/Graphics-Drivers-for-Intel-G41-Express-Chipset)

If they don't even try to install, try running the installer in compatibility mode for win7.

Not at all guaranteed, however sometimes older drivers are fine on newer versions. (My laptop runs Win10, came with Win8 and has no drivers past 8.1, but they all worked with a bit of tweaking)

Otherwise, yeah, you'll need to go back to 7, or install a dedicated graphics card (which I believe you should be able to do with your thinkcentre computer)

How to downgrade my computer from 8.1 to 7?

Thats mean i need to buy i window CD for installing!

Not necessarily. Did your computer come with Windows 7 installed?

If it did, you'll most likely still have a key for it.

If there's a sticker on your computer sorta like this:

The blacked out part there is the Windows key. You'll use that when you reinstall.

Otherwise, you can find the key by following the guides here: https://www.howtogeek.com/206329/how-to-find-your-lost-windows-or-office-product-keys/

Once you have the key, write it down somewhere (not on the computer), and let us know (do not post the key here, if you need to post a screenshot, block out most of the key)
