About a month ago I had a display error while gaming, where the view went off center, with a black bar in the center of my screen on a single monitor and the cursor crossed from one side of the screen to the other. The black bar seemed to be the edge of the display. A system restart fixed that problem.
The next day I added a second monitor to the set-up and for several hours everything was working fine, until my computer froze and I was forced to hard reboot. After that, my computer booted through the BIOS and Windows was starting to load before my display went black.
Back on a single monitor, I was able to boot windows in Safe Mode, and went through a process of rolling back drivers. Rolling back the drivers didn't fix the problem, so I tried reinstalling the drivers. Reinstalling had my windows begin to start like normal, reaching the desktop, but a moment after that the display went black again.
I uninstalled the video card and plugged my monitor into the motherboard integrated graphics and my computer was able to start and run normally.
While running off of the on-board graphics, I would experiences instances of 'stuttering', with the computer briefly freezing, never for longer than a second and never very often (5-6 times per day).
Shortly after that I was able to get a hold of a new graphics card, believing that to be the problem, but after I installed the new card, my computer would no longer boot. The fans would start up, the case lights would come on, but there would be no display, and no power to any of the peripherals. Connecting the monitor to the motherboard while keeping the card installed had the same result. Uninstalling the card and connecting the monitor to the motherboard had the system boot normally.
Installing a new PSU has the same problems as before - with the 6870 installed, the fans spin up, case lights come on, peripherals power up, display starts, motherboard/BIOS info appears, but then the display goes blank.
With the 370 installed, the fans spin up, case lights come on, but the peripherals do not power up, and the display doesn't start.
