Had a power failure to one of my XP systems. Had to re-load op sys and software. Boinc loads and shows enabled on the task bar, but when I try to engage the boinc manager, it just stalls on the "communicating with client" box. System then times out to the Boinc screen-saver which proclaims "boinc is not running". Any ideas how to fix? Found an old thread from 2009 that wasn't much help. While boinc was enabled on task bar, I've run GPU-Z. That shows no GPU activity, which leads me to believe its not crunching.

...things in the world of BOINC have moved on along way since 2009.
First thing I would do is check that you've got a current version of BOINC (from the servers here) and not an old one.
Next, make sure you've got a valid driver set for your GPU, get that from Nvidia or Geforce - do not use "vendor supplied" or Microsoft.

1. You did not allow boinc.exe and boincmgr.exe through your firewall. These two parts of BOINC need to be able to talk to each other on TCP port 31416. Usually putting boinc.exe and boincmgr.exe in your firewall's trusted zone fixes this. Just restart BOINC afterwards.

2. The client was stopped for whatever reason and only BOINC Manager was kept running. Exit BOINC Manager and restart it to see if this fixes your problem.

3. Another program has taken up port 31416. In this case you will have to figure out which program does this and exit it, then make sure that BOINC starts earlier than the other program.

4. You had a GPU of some brand in your PC, have since removed it, but didn't uninstall and clean out its drivers. Best do so, to get BOINC to work with you.
