I've recently purchased a machine and I'm having issues with using multiple displays. I have two BenQ monitors connected to a HD 7850 card, one via DVI and one via HDMI. The setup runs fine with dual displays when doing everyday tasks, but when i switch to gaming (literally every game of the almost two dozen I have tried), invariably the PC will intermittently either freeze or shut itself off. I am unable to reproduce this issue at all when using a single display connected through either the DVI or the HDMI ports.
The specs of the machine are as follows:
Graphics Card: Gigabyte Radeon HD 7850 2GB GDDR5
Catalyst Driver Version: Currently 13.1 (have rolled back to 12.x same problem)
Operating System: Windows 8 64 bit (have also tried win7 32 and 64 bit same issue)
Issue Details: Having dual displays connected to the Graphics card causes intermittent freezing/crashing/shutdowns of PC. Does not occur with a single display.
Motherboard: MSI Z77A-GD55
Power Supply: 600w PSU
Display Device(s): 2x BenQ GL2440 (One connected via HDMI one via DVI)
Applications and Games: Have tried a range of games from low end legacy games to high end current, same problem occurs.
CPU: Intel i7-3770K
Any suggestions anyone could make would be greatly appreciated. I'd really like to have this working with dual displays.
