PCH or SIO Dead? Maximus VIII HERO
Hi yall (sorry for my english)
I got an Asus Maximus VIII hero board that didnt start and react to power button at all. cmos and bios resseting didnt help so I shorted the green atx_enable wire to ground inside the 24pin atx plug and the board startet but code 00 was displayed. After that magically the powerbutton started to work again, but now the board only gives Q-CODE 00. The CPU gets warm and all voltages seem okay. All fuses are good and crystals seem to work. The pch gets warm. I tried reprogramming the bios chip and resetting cmos etc, but it didnt help me. I have boardview for this board but now I dont know what to do. Without the bios chip the board powercycles every second so it seems to read the bios code but doesnt post. Code 00 is now the problem I dont know if its related to the powerbutton issue before.
VTTDDR 0.6v is missing and not shorted when not powered. When I turn on the board (standby or normal) it gets shorted to gnd with 0ohmbyt only if powered i dont know why
The SIO gives always the RMSRST# signal o 3.5v
Caps on the PCH are directly shorted to GND but when standby is turned on the short is gone and and 3v and 1v appears on them.
All voltages except VTTDDR are good and cpu is getting hot (works on oher board)
NO status led are turning on (CPU DRAM LED etc)
Does anyone know what I should do next? Its a nice board so I want to fix it.
