a hardware problem. Modern versions of Microsoft Windows handle machine check exceptions through machine check exception windows 7 the Windows Hardware Error Architecture. When WHEA detects a machine check exception, it displays the error in a Blue Screen

Similar errors may occur on other processors and will cause similar problems. Some of the main hardware problems that cause MCEs include: System bus errors: (error communicating between the processor and the motherboard). Memory errors: parity checking detects when a memory error has occurred. Error correction code (ECC) can correct limited memory errors so that processing can continue. Cache errors in the processor. Possible causes[edit] Normal causes for MCE errors include overheating and/or incorrect hardware installation. Specific manually-induced causes include: overclocking (which normally increases heat-output) poorly-fitted heatsink/computer fans (the same problem can happen with excessive dust in the CPU fan) an overloaded internal or external power-supply (fixable by upgrading) Computer softwa

Basically, it freezes completely, doesn't respond to keyboard or mouse, CAPS won't change and alt+sys req+REISUB doesn't do anything. The problem is consistent in that http://askubuntu.com/questions/272324/any-idea-what-type-of-error-this-is-machine-check-kernel-panic after a hard reset it will be fine for a while but will freeze at some point. I've tried booting from a startup USB and this also froze so it isn't a OS problem, some hardware issue. Today I got the following messages before it froze. I guess what I want to find out is which hardware component is failing?

It shows the following error log before the restart. . Unfortunately I don't have an idea how to decode the Machine Check Exception (MCE). mcelog --ascii outputs nothing. Is there a chance that this is a software problem? The laptop is Samsung NP900X3C with the Intel Core i5-3317U processor. I use Arch Linux with the 3.13.5 kernel. kernel-panic mcelog share|improve this machine check exception question asked Feb 28 '14 at 11:58 fhucho 95129 Unfortunately no :/ I get a restart about twice a day, totally random. –fhucho Sep 26 '14 at 9:32 I think it might be the kernel version maybe? It started happening only some time after I bought the notebook, so perhaps some kernel update caused it. When did it start happening to you? –fhucho Sep 26 '14 at 9:35 I'm sorry again, but trying to answer fhucho by commenting further, I get a "you must have 50 reputation for comments". This site is not very friendly for newcomers, which may actually be the point, I guess against spammers... But it doesn't help in this case. Anyway, my address is frigaut at gmail.com. fhucho, please email me directly, it's gonna be difficult to exchange information here. –Francois Rigaut Sep 26 '14 at 10:11 @FrancoisRigaut - unfortunately sites have to take a defensive position against spammers and such and so can be a little bit uninviting until you've accumulated 50 rep.It's just how it has to be, and sorry for any inconveniences. –slm♦ Nov 1 '14 at 1:21 @FrancoisRigaut suggested over email that updating the problem might help. I tried it and the restarts seem to be less frequent and the error messages are different. –fhucho Nov 5 '14 at 15:41 add a comment| 4 Answe
while under a certain CPU or Memory intensive load - or even at random. Most of the times without throwing a Purple Screen of Death so you can at least have a notion about what went wrong. There is a VMware KB Article 1005184 concerning this issue, and it has been updated significantly since I have started to take interest in these errors. UPDATE: I have published a new CPU Stress Test & Machine Check Error debugging article - check it out if you'd like to learn more. If you are "lucky", you can see and decode yourself what preceded the crash. This is because both AMD and Intel CPUs have implemented something by the name of Memory Check Architecture. This architecture enables the CPUs to intelligently determine a fault that happens anywhere on the data transfer path during processor operation. This can capture Memory operation errors, CPU Bus interconnect errors, cache errors, and much more. How to determine what has been causing your system to fail? Read on. You will need to browse to Intel's website hosting the Intel® 64 and IA-32 Architectures Software Developer Manuals. There, download a manual named "Intel 64 and IA-32 Architectures Software Developer's Manual Combined Volumes 3A, 3B, and 3C: System Programming Guide". I highly recommend printing it, because you will be doing some back-and-forth seeking. Now, to get list of possible Machine Check Errors captured by the VMkernel, run the following in your SSH session with superuser privileges: cd /var/log;grep MCE vmkernel.log this will output something similar to this: Most of the times, the VMkernel decodes these messages for you - on this image you see that there are plenty of Memory Controller Read Errors. You can see more closely where the problem originates from: CMCI: This stands for Corrected Machine Check Interrupt - an error was captured but it was corrected and the VMkernel can keep on running. If this were to be an uncorrectalbe error, the ESXi host would crash. Logical CPU number where the MCE was detected: This particular host had Dual 8-Core Intel Xeon Processors with HyperThreading enabled. For all other occurrences of this MCE, the cpu# was alternating between 0-15 this means
