Заголовок сообщения:  n4030 (Intel) Power Problem

Device : Dell N4030, DJ1 Discrete Ver : 01
Problem : Over voltages.
3.3v : 3.7-4V.
5v : 5.20V
3.3V ALW : 3.30V
5V ALW : 5.05V
Vga Core : 1.50-.160V (Too high Ati 216-0774008)
Cpu(62882HRTZ) : 1.52V
RAM(RT8207GQV) : 1.80-2.10V
PCH VTT : 1.40-1.80V

It came with short circuited network chip(lan) and usb power cores. Chipsets were heated. Power button was runnig but there was no video and beeps. So I changed these parts;

-Atheros ethernet chip
-USB Power Cores
-EC Nuvoton NPCE781BA0DX
-Reflashed EC, Main flash.
-HM57
I heard error beeps but no video
-ATI 216-0774008

Finally I see startup screen but now it started to blue screens. I tried with 65W and 90W power supplys still same. When the card is cold voltages are normal for 10 seconds and then gets higher.
Second changes,

Sys Charger = BQ24745 (I fixed this situation before by changing sys charger on dell n5010)
DDR voltage = RT8207GQV
3.3-5V Core = (RT8205B(CK=XX))
Cpu Core = 62882hrtz

Voltages are still same. Can somebody tell me what is wrong with this motherboard...
