First, check if battery led is on when you insert battery, if yes, check 3 and 5 volt and check if there is a voltage on the bios, if those voltages are present try to reprogramm bios but you should have a programmer ; don't touch anything if you not sure you can do.

Morning.

You can try disabling the on board RAM following the images attached, no idea if it works, I haven't tried it yet just keep every change in mind so that you can revert back to the current state with ease... I mean don't do it if you aren't comfortable...

Found it somewhere on this forum.

I tried to disable the ram by removing the resistors, I still have the same problem: turn on not showing anything on the lcd / external monitor, the power & numlock leds remain fixed when turning on, 1min after turn on the fan, and everything is like this
