So this problem occurs exclusively when I'm playing games.

For example, I started up a game on league of legends just a few minutes ago and everything was fine and dandy. I loaded into the game and about 5 seconds in, my monitor goes black and tells me "HDMI no signal".

This message is not new to me since it always tells me that whenever I turn off my computer or put it to sleep but the only problem is I'm NOT trying to turn off my computer/put it to sleep.

My tower continuously runs since I hear all the fans but my monitor just loses its display. I'm aware the sapphire 7870 is notorious for display issues but I thought the issue was fixed with the new batch of cards considering I've already RMA'd this card twice. While my card was being RMA'd, I used another card in its PCI-E slot and experienced no issues.

NOTE: I am pretty sure it's not my PSU.

How's your HDMI Cable? Is it capable? Do you trust it?

(I had a dollar store HDMI cable once, it could do 720p no problem, but couldn't do 1080... would result in a blank screen, go figure)

Hmmm I never thought of suspecting the HDMI cable lol. I think mine is relatively cheap, some $1 one from online. I just replaced it with the one in my TV so I'll see if the problem persists.
