Need advice with failed gpu,, Thanks

post #1 of 10
Thread Starter 
My screen suddenly started to flicker for a couple of mintes and then it eventually turned black. Tried restarting and I can hear windows starting but no display. Took both gpus out and tried them separately. Asus 4850 boots and sapphire doesnt.

I've also noticed that the fan spins very fast and sometimes a red light comes on top of the gpu (it reads "over heat protection" next to the light) but my gpu never went over 40C at idle and 70C under load on core.

I'm trying to squeeze a bit more like out of my 4850s so please bare with me and don't ask me to upgrade. Useful advice will be very much appreciated.

What can it be and how can it be fixed?

Contact Sapphire and try for an RMA, if declined, bake.

seems he has had them for a while and rma doesn't sound like an option. if you are overclocked check/lower the pci e swap out between cards and go from there.

saadkhan what were you doing when it "flickered"

I tried this card in my brother's system and same behaviour.

I earlier played nfs hot pursuit on it and it was fine. It was when i was chatting on msn that this happened.

Yeh unfortunately rma is not an option. Although it is still under warranty I don't have the receipt/proof of purchase anymore and sapphire don't do rma directly. It has to go through the retailer.

That was the most disgusting solution to a problem ever and after 5 minutes of baking at 200 C my sapphire 4850 has come back to life!!

Thanks

I've already bought a 5850!!

I dont need to mess with it. I ran furmark on it and nfs hot pursuit and it's working fine. The temps don't go over 52C!!

I didn't buy 6950 because it's £220 here and 6870 goes for £180, so I bought a Xfx 5850 for £101 on ebay last night.
