New Cooler = No Display?

[ZeroInfinity94]

Right first of I don't know whether or not this is the right section to post in.

I have just got my new swiftech h240-x installed and for some reason I can turn my rig on and then nothing, no display.
So I hit the power button comes on for a second or to then goes off then comes back on.
Fans spin, pump starts and lights come on but nothing else, no sound or video.
Have tried with a graphics card that I know works still nothing.
Any ideas whats going on?

Cheers guys.

Check you haven't dislodged any wires on the motherboard or GPU. Have you also connected up the wire from your cooler to the CPU fan header?

Can a moderator delete this thread please.
It was my fault I didn't check my bleeding memory, one side of one of the dimms wasn't fully into the slot. -_-

I have, turned out after a beer to relax with I didn't fully insert on of the memory modules. Just goes to show the stupidest little things always trip you up.

Glad you got it fixed dude, always worth performing a last minute sanity test of all components before putting the case side on
