M460 turn off misteriosly

[amarini]

I have a problem. Celsius M460. All appear perfect. All diagnostics tests are good. XP 32 operating system
The workstation randomly turns off. I lose all unsaved works.
The event takes place in a completely random.
No virus found, no temperature problem, just no question of power.
I can always restart the system with no problem
The operating system does not present any interruption and everything seems to work perfectly
The assitance told me that is a problem of motherboard and recommended the complete replacement of the car because now dated.
Is there an other solution?
It could be a problem of RAM banks?
Help me. Thanks
Aldo Marini
