Constant Interruption During Boot Process

[JamesTenebris]

Hello All,

Error
When I power on my computer it starts the boot process for approximately 1 second and then my system turns itself off completely. After another second or so it turns itself back on and then repeats this cycle several times until it finally successfully boots. Once it turns on it remains stable for use (1-8 hours consecutively). I am mostly concerned about damaging other components by running the system without knowing the root cause. Does anyone have any ideas?

System Specs
• I am running windows 7 and my system was built a year and a half ago with no hardware issues up to this point. Also I have not overclocked.
• I5-4670k Quad Core 3.4GHZ
• MSI Z87-GD65 Motherboard
• ASUS Geforce GTX 660 OC DirectCU
• Corsair XMS3 2X4GB
• Corsair TX750 750W ATX 12V Single Rail
• Western Digital Black 1TB
• Noctua NH-U9B SE2 cooler

Troubleshooting
• I have disconnected and reconnected all power to my motherboard and made sure everything is connected properly.
• I booted without my hard drive.
• I tried booting with each stick of RAM individually and in different DIMM slots.
• Checked BIOS for voltages (PSU voltages listed below)
-3.3V - 3.36
-5V - 5.08
-12V - 11.96

Thanks in advance for any assistance and I appreciate all feedback.

-James

Good first test with memory.

To rule out the hard drive build a simple USB or CDROM boot device. (Say windows recovery CD or antivirus stand alone boot CD/USB or ..) Disconnect the WD drive power and signal cables. Try booting from the CD (or USB drive). Does it always work ? IF so suspect the WD drive. If same fail leave drive unplugged and pull video card and move display cable to MB video. rerun the boot tests. Keep pulling parts until you get to a stable boot. If you have a spare power supply (or one you can borrow from another system) trying a PSU swap is another good attempt. GL.
