Random reboots, error reporting calls it BSOD, next gen hardware

The thing we don't know is how many and what processes is windows running in the background. And it almost always has something running, just more at times than at other times. The thing is, you've been having graphics card problems and not these kind. Which makes me wonder if you don't have some type of motherboard problems. If you are using a USB mouse, the Motherboard is giving the mouse power and responds to the movement, just like it gives some power to pcie slots and receives input from the cards. But, there is no test for the motherboard, it is usually a process of elimination.

I really don't know either, but it usually is difficult to see the voltage under load. The best place to get voltage readings is in BIOS, but that just shows idle readings. This is a tutorial on testing power supplies, but I doubt it will test it correctly under load. PSU - Test DC Output Voltage

Sounds good. Ask how to determine the power going to the Motherboard and to the pcie slots. I guess the real answer we would like is how much voltage is coming out of the PSU and how much power to each component under load. That is the real thing most of us would like to know. Is the PSU putting out the required power and is the motherboard VRM distributing it properly.

I can't speak for the Z97 chipset, but I'm not sure there would be a difference. But, with the Z77 chipset, if you have a dedicated GPU installed, the IGPU is disabled unless you have LucidLogix Virtu MVP enabled and installed.

I have looked over this thread again and run every dump file you've given me and come up with the same thing. Every one was a Video TDR error. TDR means the video driver crashed and tried to recover. Technically it stands for Timeout detection and recovery. When the Drivers crash, they attempt to recover to a functional desktop, in Windows 7. In all previous OS they resulted in an absolute lockup of the computer or BSOD every time. There are a number of issues which can cause this, some of which we have covered. We have tried different drivers, are reasonably certain we have a clean install of the drivers, you have tested the PSU and are reasonably certain that the PSU is putting out what it should and the PSU is plenty strong enough to run your hardware. Your temps seem to be fine, so we know it is not overheating. The one thing that keeps me believing there is something else, is that you say it did the same thing with your 670. So, unless you want to believe that you bought 2 bad cards in a row, It seems to have to be something else. For right now, I would like you to run a short test to check for corrupt or missing files.

Open a elevated command prompt ( click start, type cmd in the search box, right click on the cmd entry and select run as administrator) in the black box that opens, copy/paste sfc /scannow. If you decide to type it, notice the space between the sfc and the /. It is a system file checker which will scan your system files and attempt to correct any missing or corrupt files. What we want are the results to say windows found no integrity violations. If it says files were found but could not be repaired, close the box, reboot and run it again, after opening the administrative command prompt. You may have to reboot and run it three times for it to repair all system files. If it can't repair them after 3 reboots, let us know. Try that and let me know how it goes. Once we get those results we are going to run memtest86+. We'll talk about that tomorrow. Just please don't get ahead of me.

Good, that's exactly what we would like.

Next I would like you to run memtest86+. It is quite a long test as it needs to be run for 8 complete passes all at the same time. Please download the test from Memtest86+ - Advanced Memory Diagnostic Tool. Although the names atr similar, this testis much better than memtest86. It needs to be run for 8 complete passes or until you get an error. If you get an error, stop the test. In the link above if you will go down to the middle of the page you can download either the ISO file which needs to be burned to a CD by Windows image burner or any disk image burner you choose. Or you can download the auto installer for USB Flash drives to run it from a flash drive. Whichever you choose, be sure to download the zip file and extract it. Each Pass consists of 10 tests, each pass checks a different thing and each pass checks different things. It takes a minimum of 8 passes to completely check the ram, more passes are better. It will take quite a number of hours to do the test, so it is usually better run over night. To run the test, boot from the media you chose and don't press any keys, the test will run automatically and will continue running until you tell it to stop. It will tell you how many passes it has run and how many errors are found. If it finds errors they will show up as red lines at the bottom of the page. It will take somewhere around 9-10 hours to check my computer with 8 GB of ram. If you have more it will take much longer.
