Moo84

Hi all, I am having a problem with a new build, basically it doesn't boot, don't get the beep and no signal. All components are new (exceot HDD). I get beeps if RAM is not inserted so I know speaker works. I have tried to start it with the Mobo on a cardboard box, also tried another mobo (same product/brand new), tired it with different RAMs also one stick at a time etc. Tried to start it with only CPU/fan and RAM. Tried different PSUs (both brand new) Tried to clear the Cmos by using a screwdriver to bridge the pins. Taken out the battery for 30 secs. when I press power button, fans come on (the cpu fan takes a few seconds to get started) I can hear the HDD but nothing else happens. Here are the components. MOBO - GIGABYTE H61MA-D3V (rev 2.0) CPU - Intel i5 3450 3.1GHZ PSU - 700W RAM - G.Skill, Rip Jaws, F3-10666CL9D - DDR3-1333 2x4GB I am sure that they are compatible... What am I missing...is the CPU duff??? I've replaced/tried diff (brand new) of everything else! HELP PLEASE!!! Thanks for reading![h=1][/h][h=1][/h][h=1][/h]
