New build Gigabyte GA990FXA-UD5, 16Gb DDR3, Phenom ll X4 / AMD Fan, 2Tb SATA3 HDD.
At initial switch on machine switched off after maybe 10 seconds.
Short circuited BIOS on MB to instal original BIOS. Machine then allowed stepping thru and completion of BIOS changes and save.
Machine now comes on normally, completes POST and starts to load WIN7 from CD.
Shortly afterwards (say 70 seconds) machine closes down.
Obviously I cannot proceed further until I can load Win7 and Drivers>
FYI - I have tested by replacement the HDD, RAM. Graphics Card, and 2 X DVDs
So fault is between CPU, MB and PSU (800W)
Any suggestions welcomed
