The thing is, you are only masking symptoms. There may be something wrong, and perhaps you could save a lot of work later by fixing a problem before it turns catastrophic. from http://en.wikipedia.org/wiki/Machine_Check_Exception A Machine Check Exception, also called MCE, is a computer hardware error which occurs when a computer's central processing unit detects an unrecoverable hardware problem. Normal causes for MCE errors are overheating and/or incorrect hardware installation. Overheating can cause electrons to become more animated and thus escape from the silicon tracks, resulting in corrupted data. Some specific manually induced causes could be: Overclocking (naturally increases heat output) Poorly fitted heatsink/computer fans (the same problem can happen with excessive dust in the CPU fan) Computer software can also cause errors in this way (normally by corrupting data they are reading or writing). For example: -Software performing read or write operations to non-existent memory regions which leads to confusion for the processor and/or the system bus. 3rd party programs mcelog mcelog is a Linux program to decode MCE's on x86-64 processors -- gentoo-user@gentoo.org mailing list
