So I've started mining LTC on my old 5970, on the secondary GPU as the first was only getting 20khash/s. I left it mining over night, and then after a certain time this morning it just stopped. I can no longer connect to the Ozcoin pool, nor any other pool for that matter.
I tried uninstalling my AMD display drivers, cleaning the PC out with Driver Sweeper then reinstalling and nothing. Reaper through commandline or GUIMiner-scrypt will not work with any pool and CGminer just crashes on startup. It was all fine earlier though :\ I don't think the 5970 is dying as I can still play games with it fine.
When trying to connect to any pool I just get an output of "Share thread started" repeated a few times and then nothing happens. It doesn't seem to start mining and GPU usage stays very low. Here is how the Reaper output appears:
For context my reaper.conf
and my litecoin.conf
I've tried different ports for pools, new pools, new workers at existing pools. All result in the same thing.
Any help would be greatly appreciated.
