I have checked forums and can't find an answer. Just installed version 7.2.42, running 32 bit Window 7. GPU used to run tasks, don't know what I did to create problem.

Here is cc_config:

<?xml version="1.0"?>
-<cc_config>
-<options>
<use_all_gpus>1</use_all_gpus>
</options>
</cc_config>

Here is latest Event Log:
