Random Black Screen while playing SWTOR, Watching YouTube Etc

Ok, new PSU is in, went ahead and sprung for the 850w that way I know I don't have a power problem. I'll keep you all updated.

New PSU has been in and I've had 3 instances of the problem.

I've noticed when it occurs and recovers the Logitech Gaming Software will still be running but my G110 keyboard's G keys will not use the macro I've configured for them. I've updated the software to the most recent version and added it to the suspect list. I'm now running 8.50.281 of the Logitech Gaming Software.

Ok, still not convinced I've found the issue but I just played for 4 hours and no black screen. This is with the Logitech gaming software unloaded. Found a thread by a logitech gaming guru that said to turn off the enhanced graphics in the software (which apparently disables openGL).

Starting a new gaming session with the logitech gaming software loaded and with the enhanced graphics option disabled. I'll let ya know.

Consider me cautiously optimistic. Another 3.5 hour gaming session tonight doing everything I could do (zoning, loading etc) to try and trigger the issue. Not a single instance after disabling the Enhanced Graphics option in the Logitec Gaming Software last night as explained above.

Watched two movies before playing and a handful of youtube videos.

Not sure it's a root cause. I have a hard time believing it's the Logitech Gaming Software considering how popular logitech devices are that use the software. If this was a bug in the program I would think it was more wide spread. And even though there are a ton of people having the TDR issue I can't verify they are using the Logitech Gaming Software.

A couple possibilities exist at this point.

Most obvious is the Logitech Gaming Software OpenGL integration is the problem. Conflicts, bugs whatever.

My DirectX needs to be repaired and due to some corruption the OpenGL configuration in the LGS is causing some type of conflict causing the TDR.

Last option (off the top of my head) is this isn't the solution and it'll crash again soon. While unlikely due to the frequency of the crashes prior to deslecting the enhanced option in the LGS, it's still a possibility.

Regardless I'll post my findings. Even if that means re-enabling the enhanced graphics option in LGS and waiting for the crash.

Locked up again last night. Only once but it's an indication the configuration in the LGS isn't what the problem is. Re-seated graphics card again and I have AeDebug ready to go.

The card I use is an EVGA GTX 470 2WIN. It's a single card with SLI enabled (2 gpu's one card to provide single card with SLI). It has 3 DVI ports. 2 on the top like most, and one on the bottom. Looking at the card one DVI port is on the left (we'll call that DVI1) then you have the DVI Port on the right (we'll call that DVI2) and then you have a single DVI port below those two (we'll call that DVI3).

I had my primary monitor plugged into DVI3, and my secondary monitor plugged into DVI1. When I experienced the TDR issue my primary monitor would go out but my secondary monitor would stay on (even though the system was locked up). I'm not sure and there isn't a lot of documentation out there to tell me how a secondary monitor "should" behave during a TDR.

I said all that to say this. I've re-arranged my DVI ports to see if I get any further with the issue. I've plugged my primary monitor (Dell 30" Ultrasharp) into DVI1, my secondary monitor (LG IPS224T-PN 22") into DVI2. Unlikely but it is possible that second GPU (or some component on that secondary card) is having issues and running everything off the primary card (and disabling SLI) will resolve the issue.

I played all last night and didn't experience a TDR. If I do experience another crash I'll pull the card out and put it in my secondary machine. I'll pull the GTX 460 out of it and put it in my primary machine. If the problem doesn't occur on my primary machine but follows the card into my secondary machine I'll know the card is the issue and I'll go pick up a replacement.

Fingers crossed.
