Please provide this information:

Although you haven't mentioned any BSOD's, the info will provide us with some details so we can try to figure this out.

In general, a machine check is related to an error that's recognized by your CPU and reported to Windows. There's not usually much information in the error reports so we have to fiddle around trying to figure it out.

Most often these are either hardware problems (something's busted) or compatibility issues (either software or hardware).
