Game is randomly crashing while in the middle of Levequest/Events Constantly!

[BONKERS]

Okay, after 2 days of playing for long periods of time on the 8600 I had 0 program crashed nor BSOD/Computer lockups.

So I threw in a GTS 450 from my brother's PC that I KNOW is fine because he gets 0 issues on his PC.
Ok, Forgot I still had OC profiles for that card on my PC so My initial run was with it OC'd. I got a program crash within a few minutes.
I go through the process of rebooting and all that junk.

Start over again with 0 OC.

I get through 2 runs of the Firefall Faire and as I am about to start repairing something my whole PC FREEZES. No BSOD, just a frozen screen and a loud BZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzT sound.


So, NOW I am thinking it HAS to be my PSU.
Because the 8600 requires 0 PCIE connectors and is powered off the PCIE Bus on the Mobo.
The GTX 460 requires 2.
And the GTS 450 requires 1.

Both cards that require a PCIE connector have crashed and have had severe stability issues even though 1 has 0 issues on another PC. (can't test the 460 on that PC because it doesn't have a PSU capable of powering it. Only 1 PCIE connector)

You should get your PSU tested then. That's why I always have an alternate PSU ready in case my current one breaks (which happens at least once every 2 years). Exchanging them is a pest though... especially if they are watercooled ~.~
