470 gtx dead?

[wali22]

Hi everybody!

The problem is this:

*The pc dosen't turn on, press the power button and nothing, everything is connected (Power cables, data cables, etc)
*If i take off the vga (EVGA 470 gtx), everything works fine with the integrated graphics.
*I have the suspect that mosfets are the problem, but im not sure.
*Stoped working in normal use, 35º celcius core temp whit modified Corsair h60 on gpu (mosfets with passive heat sink)
*If i put the vga without the PciE power connectors, everything works fine, if i connect the 6 pin, it immediately shut down.
*The vga have no phisical damage on the exterior, not that I see.
*The vga was not overclocked after modify.

System specs:
CPU: Intel Core i7 3770k
Motherboard: Intel dz68db
Ram: 2x4 gb 1333 Ghz Kingston
PSU: Corsair tx750w
GPU: EVGA nvidia 470 gtx 1280 mb
Cooling (on vga): Corsair Hidro series h60

I will really really appreciate the help. Sorry for the engrish

Yeah, maybe. Could even be something as simple as a bad pcie-cable, or even a faulty power "port" if your psu is modular. I've seen that happen before. The best way to rule it out would be to slap it into a friends system and see if it works.

I would say your graphics card potentially fried itself, unless I understand you correctly that you have -additional- cooling measures on the graphics card besides the h60 unit. Just slapping an h60 on your gpu is not something you want to do. There are quite a few other parts on the pcb that need cooling.

could be from your psu since your card daws more power and your psu cant supply it. if you have another psu you can test it by using it.

maybe something is shorting out on the gpu like the mosfets heasink, etc.

psu should be fine. even if GPU draws more but thats under load.

it could also be the PCI lane... if you have other rig or your friends, try test the you GPU into other. if problem still exist, then you can think of that GPU is dead.... if it boots, then its your PCI lane. I have checked your board, unfortunately, it has only one PCI x 16 lane,.....

Yeah, maybe the best for now is put the vga in another build .
It can be the psu, but i put my old hd 2900 pro and works fine, and only use one 8 pin connector.
