Acuson X150 checking configuration issue

Hello I have a device of acuson x150, the problem started at 1st with that the device after it was being turned on while it was still on the splash screen the device kept loading for a long time, and stuck on the splash screen in which it says " system is checking the configuration" I kept waiting for a long time , and 1st thing I attempted to do was I installed new software, but when the device was turned on it was stuck on the same page of checking configurations, after 10 min an error message appeared "upgradetool failed click ok to shutdown error code = 227". I replaced the AC/DC power supply , the device has a new version of MCP power unlike the old versions of acuson x150. After replacement of the MCP power supply the fault is the same, I removed the I/O module and BE board and reinstalled them, the device's control panel started to be unresponsive, I tested the I/O module on another X150 device in another city it was working fine, I returned it and rechecked the BE removing and reinstalling. Finally the control panel started to be responsive but I am still stuck with the original fault of "stay loading on checking configuration splash screen". So does anyone could help me to to fix that issue, I would be grateful.
Have good day
P.S: while the device is loading on the splash screen while attempting to checking system's configuration, I don't hear the sound of relays opening, I used to hear that sound of them while the device is entering the ultrasound application screen.
