I recently upgraded my video card to a msi r9 390x, and upon installation, there was absolutely no issues. For about a month, I ran into no issues. About a week ago, I updated drivers and started a game. In the middle of a game the image on my screen cut out and though my PC was still running (you could hear sound effects still going on). After restarting my computer, no image would display on my screen at all.

A few days later, I went ahead and tried to start my computer (after cutting power and securing connections) and it successfully booted. I checked temperatures, tried running a game, everything looked okay. I went ahead and restarted my computer, and suddenly back to no image on my monitor. The videocard still lights up, the fans still spin - just no image on the screen. I can replicate this - every once in awhile the videocard will work fine and I can proceed normally, but upon restarting it will cease working. At this point, I got a new motherboard (I happened to need one), however same issues. Using my old videocard still works perfectly fine. At this point, I think either my videocard overheated and was damaged, or my PSU is starting to die out/not giving enough power. The r9 390x supposedly requires at least 750 watts (what I have), and is recommended to have a 850W PSU.

Here's specs:
motherboard msi z170A
CPU i7 6700k
videocard MSI r9 390x
Hyperx DDR4 16mb ram
Power Supply Corsair TX750

Any ideas how to figure out which item is going bad?

Oddly enough, it all started with a drivers update (right before a gaming session). I tried rolling back to an older driver to no luck. Maybe I'll try this again.

Update: updated the drivers, no luck.

My old gpu was a evga gtx 670. Plugging it in now, it does seem like it has some overheating problems, as its running really hot (over 70c on games it shouldnt be) (this is after thoroughly cleaning out the card of dust)
