New Build.. encountering some problems

Hey guys, this is the fourth computer I've built, but I've been using a laptop for the past 3 years and I'm out of the game in the building desktops scene.

I went with the Intel i7 3820 with RTS2011LC liquid cooler, intel DX79TO mobo, 2x EVGA nVidia 560 Ti superclocked Corsair GS800 PSU, 2x 4GB g.skill sniper ddr3 2133mhz



Everything is put together but when I plug the power into the back of the psu, the computer turns on.. sometimes it just randomly turns on when my hands or metal get close to the case. This made me think I had a grounding issue or something. It started up, the liquid cooler pump is pumping.. all fans are on.. and 10 seconds later it turns off. No Beeps.


When I remove the memory and try to start up, it does the same thing as before for one try, but all tries after that it has three long beeps ----pause--- and three long beeps again- It stays powered on until I turn it off. The led on the motherboard signaling "WATCH DOG" flickers red when it's on.

I currently have it connected to my LED monitor with a DVI-> HDMI cable but nothing appears on the screen, even when the computer stays on for a while with no memory.


Does anyone out there have any idea why I'm not seeing a bios screen, or have any thoughts on where I should begin?

My next step(tomorrow) is to take it completely apart and rebuild from scratch.. if that doesn't help, I'll take it to my friends house and start switching out parts starting witht he PSU, and then the motherboard.

Thank you for any input!

First and easiest - remove cmos battery and reset bios. Leave it out for a few minutes.
Second and a little harder - remove and inspect your CPU/socket looking for bent pins and or thermal paste residue. Notice that each of these methods only cost "time".
Third and also easy - check for shorts/unplugged wires. Don't forget the I/O panel for tabs inside a socket (usb, etc.).

most new mb use a 5v line as an electronic on off switch. i would look at the mb where the on/off reset are plugged in and see that there not shorting to the mb tray and that you have the wires connected to the right headers. also on the on/off switch and reset switch and front pannel and mb check for any solider bridges or extra solider. most of these parts now are waved and sometime there extra. if you have a meter check the voltage at the on/off pins with the ps on and the switch off there should be 0 volts. if there is a voltage there then you have a bad on switch.
