By computer box, are you referring to a case? Maybe the new motherboard isn't compatible with the gpu or the new power supply isn't a high enough wattage to support it.

edit: Twinny's advice is most likely better than mine. Run dxdiag and post it here if you can.  

This happened to me also and I also made a thread way earlier in the year. Check it out and see if you find anything.

Same thing happened to me,what did you do to fix the problem?

There's always the possibility that this new computer does not have dedicated graphics and is using inbuilt Intel, which would mean you would have to check for drivers off the Intel website.

Here's how we can find out!

• Run dxdiag.exe from the start menu.
• Write down both the 'System Model' and 'Processor'
• Select the 'Display 1' tab
• Write down the Device name and manufacturer
• Reply to this thread with all the information you have found

If in doubt, just take a screen shot of the 'System' and 'Display 1' tab and we can take the relevant information from that.

From this, we can determine if you are running a Laptop/Desktop and if you have dedicated graphics or inbuilt. From there, we might be able to give you the exact link you need to download your graphics driver.

OK so you're using Intel inbuilt graphics (and I think it's a very old chipset as well.. 2004/2005?) so I don't think you will be able to push any high-end gaming out of this.

It does, however, look like you're using a substandard default driver so updating with the Intel driver should provide a remarkable improvement.

Visit the Intel Driver Update Utility and let it find the correct driver for you. Install it and see if it makes a difference.

Getting a dedicated graphics card will boost your experience but it's also depending on other factors. Don't form out $600 on a top-line graphics card when you have slow, low-clocked RAM, slow CPU and limited PSU

You sir are quite the computer genius. But its been analyzing my computer for a long time. I guess patience is the key.
