Random BSOD's at random times often error 0x0000001E

Well after some thinking I have made a decision: I hate to dig around in the dirt of something that seems not solvable. Too much of wasted time. And since the GV-R787OC-2GD will not be available much longer and has great reviews about the crossfire mode on newegg.com I'm gonna stick to the plan.

Going to get a new Mainboard, new PSU and a second GV-R787OC-2GD for crossfire, although I've never done crossfire. It would be great if you can help me finding the perfect PSU and Mainboard.

Usually the PSU requirements they list is for the whole system, so you are still good there. Whatever the recommend, I usually go over that. I think the sweet spot for a PSU is usually 60-70%. At that it is at it's best efficiency, runs cooler with less strain and will last longer. Also, you are not limited if you decide to do some upgrades.

My only hesitation on your plan is that we have never determined if the graphics card is the problem. Do you have another rig you could put it in, or have a friend who would put it in their machine for a couple of days and test it for you? That would be the best way to go and would let you know for sure the card is OK. I would hate for you to do all of that and still have the BSODs. You would not be a happy camper, as we say.

Just a suggestion. Set your bios to optimized defaults. You will need the set your sata controller to whatever it is right now, or it will not boot. I believe Asrock default is IDE mode. Set your ram to Manufacturer's specs and set your boot order.

The dump file is totally inconclusive and does not tell us anything. But, I think you already know that. You have mad some changes to settings that has messed your system up. Technically, the dump file seems to be blaming your CPU, which is highly unlikely.

What software? The debugger listed your grahics driver in one case, in another, I got nothing in another it was a windows update

The driver is a Windows update, but notice it says HDAudBus which makes me wonder is it the HD Audio driver or the Bus.

Do you happen to have a spare hard drive that we could use for a test that would lose all the data on it? I know from the dump files it is a third party driver referenced in many of the cases. The graphics driver qualifies, but just want to do a clean install, but in a very specific way. Would you be willing to just give it a try? Better still, would you be able to try your card in another machine to find out if it is the card? The decision you made makes everything but the card, meaningless. If you are replacing the board and PSU, if they are bad, it won't matter. The only thing you are carrying over is the card. That will be the only thing that matters.

Also, I don't remember, did you update the firmware on your SSD?
