This has never happened before. At first, I used to be able to go around two-three hours at a time. Now, I'm lucky if I get ten minutes of play time. First Rust gave me issues and Arma III followed.

This is what I've tried so far:

1. Using the Windows diagnostics tool to test memory
2. Scrubbing system with DDU of graphics drivers and installing new ones (standard and beta)
3. Moved memory to different DIM slots to see if it was possibly an issue with dual-channel memory
4. Checked both CPU and GPU temps under stress (both were adequate)

I keep seeing similar threads suggesting that this is a PSU issue. How can I be sure? I'd hate to be without a PSU for a month when it may not even be the issue.

PC Specs:

Intel Core i5-4590
XFX R9 280X (stock)
Seasonic SSR-650RM 80+ GOLD
MSI B85-G43
8GB DDR3 1333mhz
Windows 7 Home 64X

So I'm at a loss as to what I should do. I'm open to any suggestions, thanks.
