Comp keeps re-starting after ripping cd's
 

ok not sure i'm in the right sopt but i have annoying problem with my desktop, has been going on a while but is really annoying now!!

I can rip 2 cd's onto the library using winodws media player but as soon as a 3rd disk goes in the computer re-starts!!

no messgae, no warning nothing just re-starts then telle me that windows xp, office has recovered from a serious problem.............

any ideas how i stop it doing this??? am trying to back up my cd collection cos the kid keeps scratching them all!!

thanks again guys
