Ok so when I leave my computer running the screen turns off, this is normal, however when I try to wake it, it doesn't come back on and I often have to hard reboot and even that doesn't always work and I end up leaving it and coming back later

Here are the specs:
CPU I5-4460
8gb RAM
Palit GTX 970
Crucial 128gb sad
600w corsair power supply

The monitor is a Benq GW2765HT and I'm using the display port cable as it's the only one I had
