If you are using windows, check the task manager and see which application is causing the problem. You may need to check the processes tab as well.
LOL, what kind of n00b do you think I am...? I am an advanced linux (preference for Debian 6.0 distro with no Gnome) and windoze user as well as a capable programmer and web coder. I assure you, I know how to use my computers beyond pressing the "power" button.
What I am telling you is that the combination of running those 4 clients together causes my laptop to react in the same exact manner as when pooler's cpuminer is running. It is not one single client/program causing the issue, it is the combination of those 4.
If you read my post again, you will see that I can run 11 different *coin clients + 4 other user programs without my cpu going to 100%. But if I run just those 4 coin clients together (it MUST be ALL 4 clients run together) it causes 100% cpu usage.
There is clearly something up with these clients.
have you tried turning the PC off and back on again??
sorry couldn't resist
but is interesting what u have found
