SERIOUS ERROR

my computer keeps coming up telling me that my system has just recovered from a serious error? the path that it keeps telling me its coming from is C:\WINDOWS\MINIDUMP, when i submit the error report its telling me it to do with c-media but cant determine wether this is the actual problem. is this because i have installed a programme that isnt working or something else? i would be greatful if someone could get back to me ASAP.

Thankyou :O)
