Hello all,

This is my first time build and I'm having some issues, here are the parts I have:

CPU: Intel Core i7-4770 3.4GHz Quad-Core Processor
Cooler: Cooler Master Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler
MOBO: MSI Z87-GD65 Gaming ATX LGA1150 Motherboard
RAM: G.Skill Ares Series 16GB (2 x 8GB) DDR3-1866 Memory
Storage: Samsung 840 Series 120GB 2.5" Solid State Disk
Storage: Western Digital Caviar Black 1TB 3.5" 7200RPM Internal Hard Drive
GPU: Gigabyte GeForce GTX 760 4GB Video Card
Case: Fractal Design Define R4 (Black Pearl) ATX Mid Tower Case
PSU: Cooler Master V850 850W 80 PLUS Gold Certified ATX12V / EPS12V Power Supply
drive: Lite-On iHAS124-04 DVD/CD Writer

All parts were assembled, but there were 3 issues:
1. There wasn't any video out.
2. Computer booted up fine, fans ran, mobo LEDs turned on, no beeps, but after restarting computer, it will boot for less than half a second before switching off. I can remove power source for awhile and try again and the same thing happens, computer boots fine, but no video out, try restarting and then it won't boot.
3. front LED doesn't light up (although I think it's a separate issue)

I've tried booting with and without GPU with both issue 1 and issue 2 occurring. Any ideas?

Did as suggested, used onboard graphics, reset BIOS, but the same issues occurred. No power to front LEDs, system boots up just fine, but no video out, after restart, system turns on for a split second before turning off.

Same issue occurs, with all 8 different possibilities of 1 mem stick.

Thanks! I now have video, and stable boots. The issue (I think) was that the JPWR2 slot (powering supp. power to cpu) wasn't making good contact. Reconnected that and solved my issues.
