Hmm, I am running 14 comps on seti@home, both the astropulse and the seti-enhanced applications. I do not see any such problems as you describe. So lets look:
1. Check in the taskmanager: do you see the application processes running?
2. How much of the CPU's resources are the applications processes taking?
3. Do you see the BOINC-processes running?
If all is ok continue:
4. Check in the BOINC-manager the Message-tab. Do you see any error messages? (often in red!)
5. Check in the BOINC\projects\slots\0 (or 1 or 2)directory for the stderr.txt file. How does it end? Exception error? Does the file report progress?
In the last two steps you should see some kind of message about the error. Post it here, please and we can try to help.
Things to check:
CPU-temp (use SpeedFan or CoreTemp).
Check with Prime95 if the CPU calculates correctly.
OK, that should get you started ...
Let us know what you get ...
