BSOD Can't identify any other pattern

pillphil, I will see if I can help. The first thing is, we have to get the computer to run again, if we can. Do you have on board graphics or another card we could try? If not, do you have a friend with a spare card? The ideal scenario would be if you have a friend that could help you, and would try their card in your machine and your card in their machine.

The problem seems to be that your card won't work at all. To try new drivers, the computer has to come on with the card installed, but as I understand, it won't. is that correct? What card do you have in it now? Also in your system specs You list a CX 500, I presume that is a Corsair brand. While it is running please go into bios and tell me the value of your +12V, +5V and +3.3V.

Also, if you don't have it, please download CPUz and post screenshots ( Screenshots and Files - Upload and Post in Seven Forums) of the CPU, Mainboard, Memory and SPD tabs. The SPD tab you can select each dim slot from the dropdown in the upper left. I only need the ones that are populated with ram. What program do you normally use for CPU and GPU temps, and what Model Sapphire 7870 do you have?

OK, your voltages seem to be good, it is not a good idea to mix ram modules, ram should be purchased in sets where the modules are tested to work together, but I don't think that is your problem. Your motherboard temp seems a little high, but I am not familiar with your board so, it could be normal.

Do you have a warranty on your graphics card? Have you thought about the suggestion to try it in another computer. From everything I can see it seems to be your PSU or the card. All voltages on the PSU look good, however that does not tell us how it performs under stress. Plus, the card you are running now does not use the same voltage as your 7870. But, if you could try it in another computer with an adequate PSU and get the same results, I think you would have your answer. You can certainly try different drivers, but that does not seem to be the problem. This will help to install your drivers. Before doing so, you need to uninstall the older drivers and clean out any leftover driver files, this will help you do that Drivers - Clean Left over Files after Uninstalling

Personally, I think it's the card. However, to be certain it would be best to test it in another computer to make certain.
