Machine check exeption

[pa0unt]

Hi


i´ve recently experienced random crashes on my computer. with no bsod or anything and no crashlogs, it just shuts down. i have just recently installed new ram and i thought that would be the cause, but after changing back to my old ram i still got random crashes. my second thought would be overheating since my cpu showed like around 50c in speedfan and sometimes a flame mark. i removed the side of the computer and put a fan to make it cooler, but i still got that crash. after googling around a little i read about event viewer and after a crash i would check the log there to see what was causing it.



i havent been doing anything special software wise, just installed a few programs like speedfan, debugger, everest, disckeeper, and the like. i have also changed bios a little but changed it back since it didnt help (amdcoolnquiet). there is a possibility that i´ve accidentally changed bios so i leave that possibility open.

Hi, Having a look at the event log it is a hardware issue which looks to be related to the mother board. The only thing you can try is to reset the bios to optimized defaults and you could run chkdsk /f from a command line but this may be more serious than that.

hi again, and thanks for the quick reply
i tried both of thoose but i still have that problem. and i ran checkdisk but it crashed at step 4. data check-something. and by crash i mean restarted itself.

hi, i found out what the problem was, windows 7 activated a kill-switch as of july 1st that shuts down the computer every other hour. Its so wierd that i didnt get any notification of some kind.
