I installed cgminer after GUIminer pooped out on me (it worked fine until after I restarted my Windows 7 machine.) Here's what's happening with cgminer.
Command entered D:\cgminer\cgminer.exe -o
http://stratum.bitcoin.cz:3333 -u myusername -p mypassword
The following appears in the command window:
[2013-04-08 18:28:50] Started cgminer 2.11.4
[2013-04-08 18:28:51] Probing for an alive pool
[2013-04-08 18:29:13] Disabling extra threads due to dynamic mode.
[2013-04-08 18:29:13] Tune dynamic intensity with --gpu-dyninterval
[2013-04-08 18:29:14] Thread 1 being disabled
Then, nothing.
My rewards on Slush's pool are unchanged from when GUIminer was working properly. Any idea what I'm doing wrong, or what I need to do to make it right?
