Strange things happen when the PS goes south. Hopefully the mobo is still operable...
I have used sparkle 250W
to replace emachines and other matx out-of-warranty if the user does not want a full pc replacement, and I noticed Fortron
has a nice 300W 24 pin matx if you want to reuse the case for a mobo upgrade like this this Asus A8N-VM
They make great media players / PVRs since they are small & quiet!
edit: I looked up the emachine part replacement
, for $160 it is not the greatest deal!
