Dusty&Raptor,
I am using windows xp OS and have a 1600+ AMD processor. I had open my case several times just to clean it and free it from dust and I'm sure the cover is place properly. This error only comes very recently. I haven't alter any info in the BIOS. Later on I'll check the status you've mention in the BIOS. By the way I've reformat it but the error still exist.
Awaiting for more feedbacks from you. Thanks a lot.
Regards,
