This problem goes back to a month ago when i noticed that during games, my monitor would lose signal and I have to restart my pc in order to get things working again. Sometimes I would be able to see the message that display drivers stopped working and recovered. I tried updating drivers, rolling back drivers, and even tried replacing my Nvidia Geforce GTX 660 with an Asus Radeon R9 270. None of these worked so I'm convinced it's not a gpu issue. I'm concerned after reading other forums that it may be a psu issue, but before I make any changes I just want to be sure that I've exhausted other options.

My current setup is

Asus Radeon R9 270
i5-4670k quad core
MSI ATX DDR3 1333 LGA 1150 Motherboard
Cooler Master GX - 750W 80 Plus Bronze PSU

Also since changing the gpu, sometimes it loses monitor connections, sometimes the game just minimizes and i need to click on it.
