Another emachine gone. I am installing a new mobo,psu and cpu in my micro atx emachine case. Keeping dvd drives and hard drive. Is there anything I should know before startup? Will the system start from hard drive like it did before mobo died? Please help ,this is my first build for daughter. Biostar gforce 6100 m9, athlon 64 3200+, thermaltake 430 watt psu, kingston duel channel 400mhz 3200 256x2. Thank you, Kirk
