Being a bit more descriptive as to what you've tried may help us out, are you able to load up safe mode?
No i can't even get to BIOS or anything to diplay but "no signal", the comp turns on with all LEDs on the MOBO, CPU fan spins,the HD spins and both GPU fans spin (using a 850W now). I also dont get any of the normal beeps when it first fires up and the front LED on the of the tower stays on like it's thinking??
I've rearranged all the RAM and tried just just one stick and still nothing...I also tried new HD and nothing
thanks for your help
