I appreciate the insight, so in conclusion you presume that the inductors have blown and i'll need to replace one/all of them?

I'll inspect my cards tonight and see if i can see any dis-coloration, if i can't and all the components are in working order? would there be another reason why the card is heating (up as if being powered), but not detected by the device manager?

probably only one....

If you cant find anything out of order, its probably the GPU itself and you could RMa or possibly bake it

Once you tear down your rig, test the card by itself to rule out or verify if it is functional.

Yeah, this is what i was hoping to avoid... I don't really want to replace the card until i have to... but it looks like getting a hold of another gtx285 might prove to be tricky, I think it may be time to look for an upgrade...

Kindly paid for by my landlord who i'm maintaining the blame on...

Also RMA is not an option since i've watercooled them both...

It may be time to invest in a UPS (battery back-up) system. You can really kill components my cutting power that harshly.

Hey Guys,

After a close inspection of the both PCB's I concluded no parts have been damaged or corrupted.

I did however notice that upon switching the PCI-e Power cables that the screen giving out a display swapped, thus bringing me to the conclusion that either one or 2 of the available 6 PCI-e arms are defect.

I do have another 2 tucked away behind the case, so tonight i will pull test them to see if they are functional and can restore power to the cards..

THANK SCIENCE the cards haven't suffered any damage!

Cheers for those who gave their input!

Hey guys,

back home and swapping the power arms has revealed that both cards are in full working order, but no matter what combination i try, only ever one is picked up in device manager.....

Could the power cut have caused my mobo (sig rig) to stop detecting 2 cards?

i've tried multiple time and its detecting each screen per gpu, but not both simultaneously....

Has anyone experienced similar?

I was really hoping to run Crysis 2 on Hardcore!

UPDATE:

Magically my Mobo decided to detect both cards and run them in sli again? a bit weird if you ask me, but I've got the electricians to upgrade the wires and junctions in my house as i gather in 1914 they didn't expect ppl to be running 6000w of computers in one room....
