I have the same problem. I own an ASUS Motherboard P8H61-M with latest B3 revision BIOS. This MOBO have an integrated GPU Intel Graphics HD.
The drivers that comes with the CD-ROM of the MOBO, the latest drivers from ASUS web page and the latest drivers from Intel web page for this particular iGPU, is not compatible with Windows 7 64 bit and/or Windows 8 64 bits.
After I install Windows 7 64bits and run the standard VGA it all goes normal, after installing the Intel Graphics driver and the PC reboot... well same story, Windows 7 logo appears, and then black screen and HDD keep loading the OS. Only way to resolve is to go into safe mode at Windows 7, and uninstall drivers of the iGPU, reboot and keep working with the standard VGA display, which in turn cant do crap and the display resolution is poor and low.
So Intel what on earth you gonna do? I wont run Windows 7 32 bit and throw out my 8 GB DDR memory in vane for just 4 GB.
Please give me an answer with a solution to this matter. Paid for something isnt working is illegal, did you know that?
