I have to report a probably bad WU.
My PC has already downloaded this WU many times before, but working on it was each time without success.

This one isn't bad. Another folder has completed it successfully.

Hi tati (team 0),
Your WU (P6041 R0 C26 G39) was added to the stats database on 2010-08-12 10:09:39 for 0.57 points of credit.

The error code for the partial return for you indicates probable system instability. Are you overclocking? You may also want to run diagnostics on memory and disk.

My CPU is working at stock speed (3 GHz).
Other WU's are running normally.

If I were you I would just consider it a fluke of some sort if it doesn't continue to happen.
