Hi there,

I've just changed over my Case, PSU and Fans but since doing so I have no sign of posting or display. I've got to where I press the power button, the LED is not present but the fans spin for a second before shutting off leaving just the RAM RGB lit and will stay lit until you cut the power. I've looked through all the troubleshooting possibilities on the thread and no luck, even cleaning then repasting my CPU and trying various unplugged components at a time.

I'm wondering whether I have a bad motherboard after the swap although everything was working fine prior to it and, I'm also suspecting the front panel IO due to no power LED?

Specs:

CPU ~ Intel Core i7 6700K @4.0 GHz
CPU Cooler ~ Corsair H100i V2 (RGB)
Motherboard ~ Gigabyte Z270-GAMING K3
Memory ~ Corsair Vengeance 2 X 8 GB @3000 MHz (RGB)
Graphics Card ~ Funds Being Raised for a GTX1080
Case ~ Corsair Crystal 460X
Power Supply ~ Corsair RM750i Fully Modular
Solid State Drive ~ Samsung 850 EVO 250 GB
Hard Disk Drive ~ Seagate Barracuda Black 1 TB
Operating System ~ Windows 10 Professional 64 Bit

(Straight from Steam Profile so apologies for format)

Any suggestions would be greatly appreciated, thanks! :)

I'm assuming by "RAM RGB" you mean that the Diagnostic LED that says DRAM next to it is lit. If this is the case, try reseating your RAM and making sure you're using the correct channel (your MB manual should tell you which one). If the problem persists, test each stick 1 at a time (make sure it is in the correct slot dictated by your manual!). If that doesnt fix it, I would guess you probably have a bad MB or 2 sticks of bad RAM. You should also look up your motherboard model on the internet to ensure that the RAM models you are using are supported.
