HD 7970 works up to right after I sign in to desktop.

While showing its age a bit , it still works well, until it would artifact and go black.

Inspecting the TIM and thermal pads I saw or thought it was a heat issue due to that are as old as the dead sea scrolls.

Purchased some fujipoly pads for Memory, 1.5m and for VRM (same), replaced them and the TIM [AS5]on GPU.

So, booted up into windows 10 1607 and after 10 min temps soared display went black.

Replaced with an old ATI X1950 pro with Microsoft basic display driver. (it works at resolutions that can be seen from the ISS). Plus no legacy drivers work with it anymore.

Any suggestions, will re-seat H/S/F later tonight, hope it works.......

l had an old Power Color AMD Readon HD 4850 do the exact same thing and I did the exact same steps to fix it. It turns out that the card itself was just going bad. It happens.

It works fine until I either game and / or stream and then temps rise real fast and fan does not compensate, might look for a aftermarket cooler for gpu and vrm.

You can try that....but I still thinking it's the card going bad. You might want to just take the money and add some more to the total and get a new GPU. The new RX 480 for $250 give or take $30 depending on manufacturer.
