PC not starting up properly

[moshingbonzo]

Yesterday my PC had a big crash whilst loading a game. After this crash the PC would no longer turn on and I opened it up. At first I thought my RAM was faulty however after some experimenting the RAM seems perfectly fine. I also found that if I placed a single piece of RAM in one of the slots it would turn on however only once. The only way to then start the machine is to switch the RAM to the 2nd slot and so on. My immediate thought is that this is a motherboard issue however I am not sure as I have recently replaced it due to a separate issue. When the PC does not turn on properly all of the fans do (including the CPU and Graphics card fans) however there is no display however it sounds as if the HDD does not start up at all.

Motherboard -- Gigabyte H97-HD3
RAM -- CORSAIR VENGEANCE PRO 2400MHz 16GB
CPU -- Intel i7-4790 @ 3.60GHz

Any help would be greatly appreciated

When posting a thread of troubleshooting nature, it's customary to include your full system's specs inclusive of your OS. Please list them like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:

Mind also stating how the rams are populated on your board? Speaking of which we;d need to know the model for your ram kit(a link would do).

The RAM were in the 3rd and 4th position and worked fine before. Now one of them is being moved between the two each time i start up the PC.

Any one know what's wrong?

Install both sticks in grey slots, and reset CMOS. If that won't fix the problem, it is most likely motherboard fault.
