helpp~~

Even after i reformat my com, the bluescreen still comes.
I rem the blue screen has the words Machine_Check_Exception.
I did a search on it, n found tat it occurs when my hardware overheat or i overclock it. I'm sure i did not overclock them, but i dun noe bout the overheating part.

A strong reason for concern is the Machine Check Exception... which is a common indicator of a motherboard failure, or a motherboard install error, or a CPU install error. Can also, but rarely, be a memory failure, a video card problem, cooling fan or other component electronic failure.
Not easy to trouble shoot. I would go back to a fundamental setup... Power supply, motherboard and CPU, one memory module, and a floppy drive. Boot to a MS-DOS or Windows 98SE startup boot disk, and run routines for as long as you can. If no problem, add a component, such as changing memory module, try again. Keep on going, adding one component at a time and retest, to see if you can force it to give you the error... This sometimes is a waste of time, but often helps you boil down the problem to something you can fix.

From limited info it's the cache memory of the CPU. Both the dumps are the same and list the following error.

Same error fixed by replacing the CPU: http://www.techspot.com/vb/all/windows/t-63392-Frequent-sudden-restarts.html
