I was posting a response, but I was beaten to it.
You may need to install Dell drivers, if Dell modified the device ID of the onboard Intel graphics device. The latest are:
http://www.dell.com/support/home/us/en/04/product-support/product/inspiron-n411z/drivers?rvps=y
They were updated in late 2013, so they should contain Win8 drivers.
Thanks for posting the Dell link ... it looks as though the tail end of the URI prevented the forum from automatically creating a link.
Tip: for those types of links - use the globe/chainlink icon (next to the smilely) on the post menu to create a clickable link.

I think this page is where you would get the driver from Intel (your specs are for your desktop and threw me off for a minute).
2nd Generation Intel Core Processors with Intel HD Graphics 3000-2000
Since you built the desktop, you're probably savvy enough to verify the hardware and choose the correct driver (8.1 x64/64-bit or 8.1 x86/32-bit)
