ABIT Fatal1ty AN9 32X AM2 small burn mark and 8.6 post code

Hey all new here i have had this comp for about 2 years now and just today when i was surfing the internet my computer shut off and i smelled electrical burn. first post code was 8.2, tried to turn it on but it would not turn on, not even for a second. so i took everything out of the computer and gave it a good cleaning.

there was a burn mark that on a small chip below the FP-1394-1 spot on the bottom of the MB. After I unhooked the cable that was there and reconnected everything i get the 8.6 assert pwm for cpu core voltage. The computer turns on for about 5 seconds and turns off. i made sure everything was hooked up correctly and all fans are working. These are the specifications of my computer. Any help will be greatly appreaciated. I am at an Intermediate/Advanced stage with computers and have built over 10. Power mgmt is not my cup of tea haha.
