Hi, I'm currently running the latest driver version 10.18.10.3379 from windows update on my Windows 8.1 machine. Upon boot the computer restarts before entering Windows. I have a spare AMD HD6540 and it works completely fine in the same scenario. If I try to switch the HDMI from the HD6450 to the HD4000 the display will never initialize and the computer restarts.
The HDMI is connected to a Yamaha RX-V373 to a Samsung LN46C550 TV.
My specs are as follows;
Gigabyte GA-H61N-USB3 motherboard (latest F8 BIOS)
Intel core i3-3325 (HD4000)
4GB Ram
