Hello fellow bitcoiners...
I would like an immediate unlock to post about a strange issue I'm having mining with GUIMiner.
I've been mining for a few days using my GTX 260 card, getting around 45 Mhashes in addition to 13 Mhashes / sec from the CPU (~58) with a nice trickle payout.
Randomly the miner quit working. I am using version 2011-06-09 of GUIMiner. Now whenever I try to start up the miner I get the error "Unable to initialize CUDA" and it won't start. I rebooted, reinstalled graphics driver, tried the latest driver from Nvidia, rolled back the driver, rebooted again...zilch. Nothing I try works. Have also googled and the only thing I can find is some old developer messages from when CUDA was first rolled out.
Can anyone shed any light on this?
