I have the suspicion that either my Intel I2500K has a hardware problem or the RAM has a hardware problem.How can i determine if there is hardware failure or exclude that?EDIT: The processor has a hardware failure indeed. I figured that through deactivating cores in the bios. It turned out that core 3 has failure, everything works fine if only two cores are activated. The Kernel panic message did point to that as core 3 was mentioned there.
Determine if Intel I processor or RAM has hardware failure?
hardware;intel
For RAM, try Memtest86+. Many distros used to come with it on their live CDs but I'm not sure if that is still the case.
