Static Discharge Disaster!? What could be damaged?

Hello all! As I was placing my Radeon 7950 back to its PCI-e -slot after dust cleaning (pressurized air). I foolishly blindly plugged the m-DP (by feeling of my finger) to the GPU. As it was almost plugged and with my finger near, there was a flashy sparky discharge which stung my finger.

After that I have not been able to get any signal to my monitor from the GPU. Everything seemed to work fine when booting - every fan worked, there's some reading happening in sys HDD (I assume it goes to the login screen) and the motherboard (ASRock P67 P3) didn't report any errors from its own debug screen. But I couldn't get any signal with any wire or GPU (I tried DVI, HDMI, m-DP and switched the GPU to my older one, HD 6870). Not even BIOS signal goes to my monitor. I tried to work my monitor with my laptop and it did, so there's no problem there.

Anyway, after switching between my GPUs and just trying my tricks or my luck. It seems now that motherboard has difficulties recognising the GPU because the debug screen sometimes reports an "d6"-error which reads in manual as "No console output devices are found" which I assume means the GPU. But still when sometimes booting, the motherboard finds all the parts and seems to work fine (except not giving any screen signal).

So best scenario imo: the PCI slot is only worn out and the motherboard needs replacing.

Worst scenario: the static discharge in the mini Display Driver output spread and damaged my GPU, motherboard, RAM, power supply, CPU or 'just' some parts. Has this happened to anyone else? Any knowledge or opinions about how much damage can a static discharge cause when it starts from GPU? It just seems to me that there is very likely a damage caused by a discharge. I just need to know what exactly is damaged.

If I start fixing this by replacing my motherboard with a new one. Is there a good chance that the faulty parts will damage the new motherboard? This is quite worrying. I'm not an expert in this field and the money to buy new working parts is quite limited. I'm in desperate need of your opinions and help because I'm unsure what to do.

Thank you for reading and maybe trying to understand the possible gibberish I just wrote. Any help is appreciated! :)

  1. Hi. That is a socket 11550 Motherboard some whatever processor you are using i3, i5, or i7 had integrated graphics. Try that. If it works then you can pretty much assume the card is dead.

    Thanks for the tip. But I think this is one of those motherboards that doesn't have any outputs for monitoring with an integrated graphics. I checked the manual and there's no mention of it. Made me really wish it had one though :(
  3. You're right. I didn't check that as i just assumed it did as it was a socket 1155 board and the proceesors on that thing have integrated graphics. You did say you tried another card, so I am pretty sure you ruled out the card. I believe you were plugging into the mini display port when that happened. If by some cahnce you have another monitor, I would try that before replacing the Motherboard.
  4. Sorry I didn't mention this in my original post. I tried get a signal with both of my GPUs with my HDTV, this was a quite unsure method because the HDTV barely got a signal as 2nd PC screen even when everything was fine. Also the monitor worked when I connected my laptop with a HDMI cable but then didn't work when I tried the HDMI with both of my GPUs.

    I wonder if my 6870 is also faulty. It has been stored with manuals and other micro chips in a paper box. Seems like it's rare that parts like GPUs break from static electricity but after this I just don't know. I'll just get that new motherboard which this time has a working integrated graphics. I just wonder how will the new motherboard handle the HDD which has the already installed Windows 7? I suspect I'll have to buy a new hard drive (good opportunity for system SSD at least) to simplify the process as I don't want to lose any data from the old C-drive.
  5. Lots of stuff getting ruled out. Ok, if you think you need a motherboard the this one will go just fine: That is going to be an issue with Windows 7 as it is most Likely an OEM copy rather than Retail. I was over at Microsoft looking and couldn't find anything pertaining to buying a new Licence. If you you replace the Motherboard and then have the same problem I would look at the Power Supply, but that is a stretch.
  6. Wonderful! That's the exact motherboard I was planning to choose. Makes the purchase a lot easier now. My W7 is indeed an OEM but I read that people have been able to reuse the OEM licence with a phone call to Microsoft support. Seems like changing of a motherboard is good enough reason to reuse the OEM licence according to Microsoft. I surely want to hope that.

    I'll soon now wait for the new motherboard to arrive. Lets see how it goes.
  7. I have also heard that a phone call to support can take care of that situation. I bought a reatil copy, so as much changing and moving as I have done, it hasn't been an issue.
