So I was testing the stability of my card because I have been getting rare crashes of my pc, only a couple times enough, but since I had some free time I wanted to test how stable my card was under load. I booted up furmark, and after a couple minutes it was doing fine, temperatures were warm, but not absurd, running mid 80 degrees c. I got bored, and clicked the X on the top of furmark and then everything went to hell. I heard and saw a spark and bright lit emit out of my computer case, and everything went black. As fast as i could I hit the power off switch on my PSU, and unplugged it from the wall. I opened the case, and was met with the smell of burnt plastic and these sights (attached)
I removed the card after it cooled a bit, and then sat around scared to reboot the computer. However, now the computer is running fine without the card, obviously I have not tried rebooting with the card installed, as I am trying to avoid destroying my motherboard or other parts or even start a fire. I am quite curious if anyone knows what went wrong, what I might have done wrong, and if the motherboard is a hazard to continue using. The only damage to the motherboard seems to be the 16x PCIE slot, luckily the transisters directly below that spot did not blow, and are only slightly blackened by the flame/spark. Would it be safe to install a new card in my PCIE 8x slot? Will this happen again, was it my PSU that may have killed the card? Also the card was not overclocked in anyway.
Computer specs are:
i5 2500k sandy bridge
TX 650W PSU
Gigabtyte GA-Z69A-D3H-B3 motherboard
128 SSD + a couple harddrives
8gb corsair vengeance 1333
and a now presumably dead 7790
