4870X2 3 red lights

Hi first my english is not that good cause im Hungarian and Romanian.

The problem is that my PC wont boot up at all. I opened the case and there were 3 red light on my 4870X2 card which is watercooled which now I regret :fou: . What i think caused the problem is that when i changed my soundcard pci slot(SB creative xfi xtreme gamer pro) (dont ask why thats a different story). I may have touched the GPU and caused a static on the card but i might be wrong. The problem has started right after Ive done the change on the pci slot.

And yes I have changed the gpu in my system with an old ge 7600gs to see if it is working And it did worked with the old one!
And yes I have put my Gpu in an other PC with same power supply and the card showed me the same lights and no boot up.
So im thinking that my GPU is gone :cry: . But can it be the powersupply (Corsair HX1000W) which I doupt cause it is a quallity one or something else that im not aware of. :pfff:

the lights on the gpu are as follows left to right: off on off on on

    4870x2 has 5 LED's, this is what the first 3 mean:

    D13=> 8 pin power unplug

    D14=> 6 pin power unplug

    D15=> Critical temperature fault

    I found this on google.
  2. can you guys tell me how to test the 8 pin and 6 pin plugs??
  3. Hi all, sorry to revive a dead thread but for some reason I cant create my own because my secondary brick computer cant see the "submit button" on the create thread page.

    Like OP from a while ago, I'm having similar problems.

    As title says, when i turn on my system, everything starts working fine however there is no display.

    im running a 4870x2, on a p6t motherboard and i7 920. I noted that when trying to boot up, the 4870x2 flash its diagnostic LED. It doesnt stay on, but momentarily flashes.

    From the bit of googling ive done, the LED's that flashed indicate no 6pin, no 8pin and overheating issues. Ive dissassembled my computer, and then reassembled it, connecting everything, and from what i can see it is indeed connected. These lights do not remain lit though, as after about 2 seconds, there are no lights lit. Contrary to what ive read, most lights remain lit.

    Ive tried reseating the GPU, the 8pin mobo is connected to the motherboard and not the GPU, and im pretty sure my PSU is fine. Its a seasonic m12 700w modular.

    Ive also tried clearing CMOS, restarted the PC multiple times but it still doesnt work.

    Any help would be very appreciated, and sorry for digging up an old thread.
