Hi, I bought a palit jetstream 1080gtx from overclockers and have just got round to fitting it into my new pc I've built. Except i have constant flickering on screen and the gpu fans also seem to stop spinning after post. I've tried with my other older 1080gtx a palit gamerock and that's working fine as usual so its not my motherboard. Tried different pci power plugs, resetting the card and making sure all connections are secure and nothing has come loose but still i can't get rid of the flickering on screen and the fans still stop. Is my gpu due for a return or is there anything else I can try perhaps?. Ta
