Hi Guys desperate need Of help here

Bought a pre built 2 weeks ago .

Amd a8 7650k OC 4.2ghz
Intregrated r7 graphics
500w psu
8gb ram
Msi a68hm Grenade mobo

All was good - bough an gigabyte gtx 750ti 2gb to upgrade

After a few try's to install I could not get the gpu card to start (the 6 pin connector branched out to two long connectors ? I tried to plug them into empty connectors from the psu is that correct?)

- fans wouldn't move - in one of the attempts to start the pc I pressed the button while the pc was on its side

Now the pc won't start with or without the graphics card

The blue led light flashes and cpu fan switches on for half a second and off

Checked all connection on motherboard are secure

Anyone advice would be appreciated !
