My computer has been shutting down during sleep. It will wake OK within a few minutes, but after more than 10 min it will have crashed. Windows reports abnormal shutdown on restart. Most recent minidump files are attached.
This file athrx.sys is 2229608 bytes 11/5/2010.
I located this file fro download on another site and it is 1,542,656 bytes.
Could be infected, but virus scans are OK.
I would really appreciate some advice on the best way to proceed. Thanks
