I built my own computer and every time it has to update it doesn't boot. It stops at the Boot screen and goes unresponsive. I have to hit the reset button for it to continue. Here's my specs. http://pcpartpicker.com/p/phqvxr
Check your MB BIOS version, just make sure it has 2.10 at least for the i7, how to http://www.asrock.com/support/index.asp?cat=FindBIOS
If the MB has the right version BIOS, something like that means the BIOS setting or hardware compatibility has problem.
