Sounds like the card is defective. Downclock the card by 100-200MHz on both the core & memory to see if it helps stop the crashing.

Sounds like vram failure.

Am I going to get a reply from any of the admins or anyone at all or is this just going ignored?

Like Sajin said. Seems the card is probably bad, and needs to be RMA'd.

Right so one of the support team told me to open an RMA after which a courier would be arranged to pick up my card this time due to the replacement not working properly.
 
I have just send them the reminder email I was asked to send in the support ticket to remind them that the card is to be picked up, I have received a reply from someone else now telling me that they cannot arrange for the card to be picked up and that I am myself to foot the cost for postage AGAIN.
 
I understand the first time sending in the card and paying for it myself that is perfectly fine, however to receive an unstable replacement that constantly crashes and now I am being told to pay for it myself after being told that it would be handled by the RMA team?
 
What is going on here? I have seen this happen before and the team have usually handled the cost of returning the replacements so I am genuinely surprised about this.
 
I cannot afford to send these cards for a SECOND time... why is this happening now?

Call them on the phone instead of waiting for them to respond here on the forums.
