Important Notification about Power Issue

NForce chipset is very sensitive to ESD (Electrostatic Discharge), therefore this
issue mostly happens while the users intensively swap memory modules under S5
(power-off) states, and the power code is plugged while installing modules. Due to
several pins are very sensitive to ESD, so this kind of memory-replacement actions
might cause system chipset unable to boot. Please follow the following solution to
avoid this situation.
Unplug the AC power cable (shown in figure 1) or unplug the JPWR1/ PCIE_PW1 &
JPW 1 power connectors (shown in figure 2 & figure 3) before the 1st installation or
