Greetings,

I recently built a new computer and I am having trouble having it post. When flipping the PSU on, the CPU overvoltage jumper light on the motherboard (Asus Z97) turns green. The CPU is a i7-4790K. The PSU is an EVGA 850 B2. I have moved the jumper to pins 2-3 and the light still turns green after flipping the PSU switch. The computer will not post (no beeps, powers on, remains idle, no BIOS screen).

Full specs:

Tower: Corsair Carbide Series 200R Black Steel / Plastic compact ATX Mid Tower Case

Motherboard: ASUS GRYPHON Z97 Motherboard

PSU: EVGA 850 B2

CPU: Intel Core i7-4790K Devil’s Canyon Quad-Core 4.0GHz

Video card: GeForce GTX 970

RAM: 2x4GB

Hard Drive: Seagate Barracuda 2TB

Optical Drive: Samsung DVD burner

Do you have a speaker in the pins for the post beep? Performing a cmos reset is never a bad idea. Which jumper are you flipping pins on?

Could be a lemon power unit.

Do you have onboard video? If so take out video card and onboard video instead.

Use one stick of memory. try again
