Except I have a more serious problem. About 1 second after I get the popup, before I am even able to click ok, the system hangs. I am unable to move the mouse at all. I have a Zalman CNPS9700LED, which I am controlling with my motherboard. My CPU is an AMD Phenom II x4 965 BE. It's overclocked to 3.8 GHz @ 1.45vCore.
I should also note that this error message wasn't popping up until one morning I woke my computer from standby and Windows 7 informed me that I had to re-activate my copy of it because either my hardware or hardware drivers had changed.
More aboutwarning system lockup
Hmm - interesting problem - especially the process that is producing the message - gotta ponder this for a while...
Im having the exact same problem, same mobo. Since I added the 5770 when warning pops up it locks up completely. Have to do hard shut down an reboot.
