I have an Aspire M with an inmail daughter board
System had been working fine prior to moving it
To another floor in same building

The system just locks up you still have displays
But nothing eles once you reboot it all come back
For a while

I thought it was a bad CPU so I replaced
It with CPU / UPG (128) ports

It was working for about 2 weeks and stated happening.again

Had customer remove from UPS plugged directly into the wall
She said it happened again

I was thinking possible bad VM card

Very strange was working fine for years

I also removed from Network


Any thoughts ?
