Hi all
So here is what happened. I was finishing up my case lighting (bitspower cold cathodes) and needed an extra molex power plug for one of the lights. I have a Corsair HX1000W molular PSU so all I had to do was plug in a string of extra molex power plugs and connect it up. As I plugged the cold cathode power into one of the new molex plugs, a little chip on my GPU popped smoldered. I immediately switched off the PC and unplugged the power. Upon further examination, both my GTX 580's had blown at the same spot.
I disconnected everything to do with the cold cathodes and swapped out the fried cards for an old HD5770 I had. The system powered up fine although the BIOS had reset. Was able to get into windows with no problems. I turned the computer off and turned it on again but this time it powered up for a second or 2 and shut off again. After flicking the switch at the back of the power supply off then on again and re-connecting the power plug, it started normally.
I have now rebuilt the entire PC and examined every component to check for visible damage and the motherboard and CPU appear to be fine. There are no blown capacitors or chips on the motherboard that I can see and same with the CPU and CPU socket. The HDD's appear to be working fine, same with the CD drive so I am hoping everything will be ok. I am about to order a GTX 780 and an new Corsair AX860i PSU. ( I don't trust my old PSU, especially seeing as the system was only powering on sometimes after the incident)
What are the chances of there being unseen damage to the motherboard or CPU? As I said, the system booted fine and I even ran Prime 95 on the CPU to ensure it was working correctly. The motherboard (ASRock z77 Extreme6) and CPU (I7 3770K) are practically brand new. I am hoping the charge went through the GPU power connectors and not through the motherboard and through the PCI slots.
I have no Idea why or how this has happened but lately we have been experiencing some pretty stormy conditions. One afternoon, there was a storm not far off and I was about to switch off the PC and unplug everything when a lightening bolt hit not far from my house. The power went off then on again and it appeared no harm was done. Maybe this blew the over voltage protector or something in the PSU?
Anyway, input into what might have happened and what I should do will be greatly appreciated, this really hurts as I have spent a lot of time and money on this rig. Needless to say I am never touching cold cathode lighting kits again, not sure if it was the cause but I am not taking the risk.
Attached is an image of the blown chip on one of the cards. Sorry for the poor Picture quality, it was hard to photograph.
