Hoping someone can help. I've got a KV8-MAX3, it had been hanging intermittently and finally wouldn't boot the other day. I popped open the case and found that the Northbridge fan had burnt out. I replaced the fan and am still having the same issue. The computer comes on, displays the Abit splash screen and just sits there. The board displays code 52 which I believe is a memory check. After close to five minutes it proceeds to a 7F and displays a screen that says CMOS checksum error, defaults loaded. Asks you to push F1 or delete. The system doesn't repsond to any key presses. I have tried clearing the cmos, replacing the battery and pulling memory modules. I'm out of ideas here!\r\n\r\nThanks in advance!
