The model is MSI IM-GM45.
The cpu is Q900, which is confirmed from MSI by email.
But when short the switch of power supply, only the cpu fan is running, totally no video output. I changed 2 LCD monitor, 2 video cable(DVI, VGA), totally no display. Tried 2G memory, 4G memory.
Sometime, when bootup, after a few seconds, the cpu fan will stop and start, and the board seems auto-reset and start again.
Any suggestion. Thanks.
