New PC not powering up

December 13, 2011 at 02:43:04
Specs: Windows 7
I recently built a new PC. When I press the power button, the fans spin up (case and CPU fans) can hear the hdds spin up, the DVD burner is accessed, but the the systems hangs.

The internal speaker does not sound, The power LED on the motherboard lights up as well as what is called a Heart-Beat LED (it blinks once per second).

Here are the system specs:
Dual AMD 12-core 6166HE processors
ASUS KGPE-D16 Server board
2 Pny GTX 560Ti OC2 video cards with SLI connector
Soundblaster PCIEx Titanium XFi Sound card
64GB Corsair XMS3 DDR3 1333 memory
4 2TB Western Digital 7200RPM hard drives
1 2TB Toshiba HDD
1000Watt CoolerMaster SilentPro M Modular Power supply
ThermalTake Level 10 GT Gaming Case

Now as for what I have already done:
Tested the processors in a known good system
Switched cases
Tested RAM in known good system
Removed and replaced BIOS battery
Cleared CMOS RTC

The MB was benchtested by ASUS

Any suggestions appreciated.

Remove everything except CPU, RAM and video from MoBo (use minimal RAM). Test unit (with monitor) outside of case if possible. If unit powers up normally (of course it will complain about no boot-device, etc.), add components back one at a time until the unit malfunctions. If it doesn't boot, then one of the three (CPU/RAM/Video) or MoBo itself is to blame.

"The MB was benchtested by ASUS"

It also should have been benchtested by you before installing it in the case. NEVER skip the benchtest process. Tear the system apart & start from scratch - begin with the benchtest.

also make sure this psu is enough its powerful but lets make sure its enough the system is huge 2 gtx 560's, 12 core amd cpu, 64Gb ram, 3 hard disks maybe
post amps on the 12V railing of ur cooler master.
also dont ever build a pc without benchtesting first,
try the system with small ammounts of ram then add one stick at a time until the problem happens. try one graphics only then try the other check if thats the problem, check if the cpu is installed properly heatsink and cpu itslelf are inserted correctly into the socket, post back results

computers are a second home

Is is possible that your case standoff's are shorting it?

Testing only works if you test in exact same model of motherboard.

Does it have a built in video adapter? Does the keyboard work for cap locks on and off?

Can you see anything at all on display?

Can you remove all memory and cpu and get a beep code?

Removed everything from case and tested system. No beep codes indicating lack of memory. No video on screen. Retested RAM, power supply and processors in a known good system. RAM works. PSU works. But, I managed to narrow it down to one of the two processors. Thank you all for your tips. I am in the process of purchasing replacement processors. Will update if that is all that is wrong.
