MCP61SM-AM is it fried

Ok here we go, i got a MCP61SM-AM mobo off a friend of mine who broke his PC, this is a Foxconn mobo slightly modified for acer (pulled out of an acer aspire t180-OA7Z). First thing i noticed was he destroyed the CPU (demolished the pins) it was originally a AMD sempron 3000 AM2 socket so i upgraded it to a AMD Athlon 64 dual core 5000 . Then i started to get error beeps which are continous long beeps with no monitor input. I have replaced the RAM modules and still get the same error beeps. I used a mobo diagnostics card and the digital display reads C1 which according to the manual is "OEM specific - Test to size onboard memory". Now ive come to the conclusion its either the onboard GFX (which i don't have another GFX card to test yet and don't know whether its worth purchasing one to try it) or the mobo is fried.

Any help or ideas?

Hi yes the CPU is definatley supported as there are people who have gone upto a 5200+ and 5400+ but i wanted to play it safe with the 5000+ that acer said this mobo supports. Thanks for the reply.
