[SOLVED] can a broken motherboard to destroy card graphics?

[dimitris064]

I bought a New graphics card for my pc and I tried to put it on it work for several minutes I even install the drivers and suddenly I saw black screen and my pc restart then it happed again and again after that my pc starts with the motherboards graphics so my motherboard doesnt recognize this card graphics anymore I take off the card and I saw that I broke 2 capacitors I went to a friend pc to see if his motherboard recognize my card but no luck can this motherboard with 2 broken capacitor to destroyed my card?

It would be unlikely for the mobo itself to have killed the GPU, but it is possible for a faulty PSU to damage both the mobo and the GPU. Popped capacitors are mostly the result of bad voltages and/or overheating. So it's more likely for your PSU to have damaged both the mobo and the GPU, than the mobo itself killing the GPU.

look I broke up the capacitors and I bought today a New psu the motherboard is working fine with his own graphics but the graphics card cant give a singal so idk

you maybe think tha the problem is the broken capacitors or no?

Well it's not impossible, but very unlikely. Theoretically if there are any irregularities in the voltage, it could damage and short the components, but the mobo doesn't have enough power to actually destroy a GPU. But yes it's possible, especially if the card is entirely powered by the PCI-E slot.

the card is strix rx 470 4gb and has 6 pin external power and the mobo is asrock h81m what do you think about that

Sounds more like the manufacturer installed the caps backwards and they gave out after a short time.

I don't undertand you what do you mean

I don't undertand you what do you mean

If what you are talking about are electrolytic capacitors, they have a specific orientation (+/-) If the cap is install backwards (negative to positive, positive to negative) and power is applied, they'll pop.

no it was OK I installed the GPU and probobly I broke them up

I have to clarify when you said you broke two capacitors, do you mean you specifically broke the caps or you found them damaged when you uninstalled the card? Cause I maybe misunderstanding the problem.

but I didnt noticed it immediately

O ok then. Well depending on what they were being used for, yea that can royally screw up a card. If they were decoupling capacitors then the voltages could be noisy. If they were coupling capacitors then you have signal loss.

A GPU draws power from both the mobo and the external connector. So it could've been shorted by drawing irregular power from one of its power sources (mobo).

 

[dimitris064]

there where 2 Capacitors 16V 100UF near to the PCI-E slot

 

[dimitris064]

I will install New ones but idk what will happed with the card

I went to a guy and he replace 12v capacitors to 50v Is that normal or I will have problem

Higher is better. That is just how much voltage those capacitors can handle before blowing.
