New PC Build... Case Shows Power, Won't Turn On

Let me start by saying that I am a total newbie when it comes to building computers, and I assembled my first one today.

Here are the parts... (it's an exact copy of the "Striker's 'Gamer's Delight' Build" by "striker410" found here:

My problem is this: The computer case is showing that it has power from the power supply by way of a red light, but the computer itself won't turn on. I'm looking for advice as to why this is happening.

Processor: Intel Core i5-2500K Sandy Bridge 3.3GHz (3.7GHz Turbo Boost) 4 x 256KB L2 Cache 6MB L3 Cache LGA 1155 95W Quad-Core Desktop Processor

Motherboard: GIGABYTE GA-Z68X-UD3-B3 LGA 1155 Intel Z68 SATA 6Gb/s USB 3.0 ATX Intel Motherboard

RAM: G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory

Graphics card: EVGA 012-P3-1571-KR GeForce GTX 570 HD w/Display-Port (Fermi) 1280MB 320-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card

Hard drive: Samsung Desktop Class Spinpoint F3 1 TB SATA 3.0 Gb-s 32 MB Cache 3.5-Inch Internal Bare

Case: COOLER MASTER HAF 912 RC-912-KKN1 Black SECC/ ABS Plastic ATX Mid Tower Computer Case

Power supply: Antec EarthWatts EA750 750W Continuous Power ATX12V version 2.3 SLI Certified CrossFire Ready 80 PLUS Certified Active PFC Power Supply

Cooling: Cooler Master Hyper 212 Plus 120mm Sleeve CPU Cooler

DVD Burner: Sony Optiarc Black 24X DVD+R 8X DVD+RW 12X DVD+R DL 24X DVD-R 6X DVD-RW 12X DVD-RAM 16X DVD-ROM 48X CD-R 32X CD-RW 48X CD-ROM 2MB Cache SATA CD/DVD Burner

I have everything installed as per the instructions and the New Egg tutorial I watched on YouTube.

Thanks for your help!

  2. Hi there.

    Now when you say "won't turn on", are we talking computer or monitor? If nothing shows up on the monitor, it's probably an easy fix. If the computer won't boot, that's another issue.

    Yes, I finished all the numbered steps, and I was about to move on to the other steps.
