It would appear that the motherboard or CPU is still hosed. The dump indicates a hardware failure caused by a third party devise on the CPU bus. In this case, the event log supports this and points to the Northbridge bus. This may be caused by the CPU not being properly seated or damaged/dirty contacts. (Perhaps thermal paste on the contacts.) If you are not familiar with removing, cleaning contacts and reinstalling a CPU, you should get help from a competent PC specialist to examine the CPU and socket contacts.
