Hi everyone,
Two days ago my main PC stopped booting. Everything gets power, disks, optical drives spin etc, but no POST and no display on the monitor. The motherboard is per the thread title. On this board is a small LCD screen which echoes the boot up steps. My LCD displays CPU INIT and then CODE INIT which apparently is a common fault on these mobos. If I remove all the memory modules the LCD will display only CPU INIT.
Trawling the net has come up with various ways of adding memory, clearing BIOS and so on, I think I have tried all of the steps other people have mentioned on various forums but no joy. I have also tried another known working CPU (I'm writing this thread with it in another PC).
It seems to me like I could have a corrupt BIOS chip. Winbond W39V080APZ
Before I send off for another BIOS chip I was wondering if anyone can tell me if I can manually clear this chip by applying a small voltage across pins? How is this normally achieved in electronic terms? I have removed the chip from the motherboard. Any other suggestions would be appreciated, except to buy another mobo .
Thanks,
Ed.
