1 core keeps shutting down - Page 2

post #11 of 12
See, if this was a Quad, AMD would've marketed this defective core as an 8000 series /sarcasm. Seriously though, it might be an issue with using 64-bit XP. Drivers and such aren't always there. Try Vista or 32-bit XP and see if the issue continues. If so, you might need to contact AMD and demand a triple core for your trouble /syllogism.

It's happened twice now; evrything running AOK and SMP folding overnight!
I get up and the computer is shut down.
I restart and no errors or problems-- everything appears normal, then when I try and run SMP again I get "SMP designed for multicore computers" (Or similar) then
I check cpuid and see
"1 core 1 thread"
I check with task manager --sure enough-- Only 1 core active!
Everest, Sandra-- Same thing -- 1 core active.
The first time it did this I tried everything I could think of; No joy!
The only thing that fixed it was a complete reformat and re-install.
What gives?
Thanks for any hints- I'm stumped (doesn't happen too often )
Cheers
SpcCdr, make sure in the Device Manager under "Computer", it says "ACPI Multiprocessor PC". Please check that and let us know.

Hope this helps
