Gigabyte H87-D3H Shutdown/Reset


5 posts in this topic

Recommended Posts



my current setup is as follows:


M/B: Gigabyte H87-D3H

CPU: Intel i5-4670

Ram: 16GB Vengeance

GPU: Asus GT640


I am currently facing problems shutting down and restarting my computer. Whenever shutdown/reset is initiated, OS X exits nicely and my monitor goes to sleep mode, however my desktop is still switched on. It just hangs with my desktop power LED still switched on.


Also, when I plug in my external hard drive into the front panel USB (USB 2.0), it detects my hard drive and allows me to do everything. However when I eject and unplugged it, OS X resets and hang at the blank screen.


Everything else runs nicely. I do not know if this 2 situations are linked. Please advice. thanks.
