Hi,

I just finished replacing the stock CPU cooler with a Cooler master Hyper TX3. Once I'd reassembled everything I discovered that my PC will boot but won't display any output on the screen, the CD/DVD drive is also making a clicking noise in this pattern: clicks 5 times, pauses and then clicks a further 2 times and keeps repeating this.

I've tested it with a different GPU and it still won't display any output, CD drive making clicking noises again but only does a two click pattern.

Any ideas what could be causing the problem?

Specs:

Motherboard: Gigabyte GA-MA790XT-UD4P
Processor - AMD Phenom II X4 950 BE 3.2GHz
GPU - Sapphire OC HD7850 2GB
RAM - Corsair DDR3-1600 4GB

Thank you

Pretty sure it's installed correctly..
And I didn't need to take the motherboard out at all so I would have thought it wouldn't be that?
