After about 30mins to and hour of playing intensive games like GTA:V, Battlefield, SR:IV, Hitman: Absolution, etc. my computer hangs and I have to manually reboot.

I have tried using Catalyst to underclock my Core Clock to 500MHz and Memory Clock to 750MHz yet it still happens (I think it buys me time though). GTA:V still runs smooth like butter.. Until my computer explodes -.-

Using MSI Afterburner my temp stays at about 58C when playing GTAV and when I minimize GTAV it goes to about 44C which I may be wrong but that shouldn't be it overheating right? I have the fan controls go up as the temp does, usually averaging around 75%.

Using Task Manager my CPU usage is around 55%, Memory is 70%, and my Disk is 20% (recently fixed an issue with it maxing out).

I really have no clue what the issue is, I've read a lot of different forums which have different issue such as voltage usage, BIOS issues, etc. but I don't want to mess around with anything since I am not that great with computers 😛

Here is a screenshot of what it looks like when playing GTA:V for 5minutes: http://i.imgur.com/kPIfhfr.png

(I also recently replaced my PSU as my old one broke, I still had these issue way before my old PSU broke and I still have them now)

Extra note: Why does MSI Afterburner say I have 2 GPU's? Is that because I have a dual monitor setup because the second GPU doesn't seem to do anything. Here's a screenshot: http://i.imgur.com/RMUJW4a.png It doesn't vary much from that

Please don't tell me I have to replace PC parts, I spent all my money on this damn PSU x_x


NOTE: Ran Memory Diagnostic tool, came up perfect
Ran OCCT twice, First time lasted a minute and the second time lasted 2 minutes (in a 1 hour time trial)... This feels like its an issue.

Specs:
O/S: Windows 8.1
CPU: AMD FX 9590 Eight-Core Processor 4.7GHz
GPU: AMD Radeon HD 7900 Series
PSU: Thermaltake Smart 850W Power Supply
MB: Gigabyte Technology somthing something idk
RAM:8GB
 
Solution
Change the PSU. Thermaltake Smart series power supplies are almost as bad as their TR-2 versions, which are very bad.

I'd almost guarantee that's the issue, but there is a small amount of room for it to be another issue. In almost every case I've personally encountered where a Thermaltake Smart series or TR-2 unit was being used, and was having issues, it was the PSU. It's a tier 4 unit, which is WELL below what you should be using for a very high end GPU like that. You want a Tier 1 or Tier 2 unit only. Nothing Tier 3 or lower.

It's always possible you have other issues, or A unrelated issue, but I really recommend you do that regardless. The fact...

The fact that it doesn't do it all the time, and takes a while for issues to occur, really just confirms to me that it's a PSU related issue and once the PSU gets warm, it fails to do it's job.

I have read up on the specs of the 7900 series. the minumum core clock for the 7950 is 850mhz, and 925mhz boost clock, same with the 7970. Underclocking by that much will surely cause stability problems.
