New motherboard, CPU and graphics card, no display. Help!

[BeatrixKiddo]

I wonder if anyone can help me with my no display issue.

I have just replaced my motherboard (ASUS M5A99x) my CPU (AMD Bulldozer FX-6350 Am3+) and graphics card (ASUS Radeon 7870 HD)

Everythings come on and would appear to be working (lights/fans on etc) but theres no display on the monitor at all

If anyone could help me solve this issue id be very grateful.

hi there the things i would try for this issue.

-make sure the CPU power supply is plugged in at the top of the motherboard the 4 or 8 pin connector ! i have done this many times and forgotten it.

-clear the CMOS (power down the system unplug from the mains and take out the little button battery on the motherboard and reseat)

- check the ram is not faulty (if you have two sticks try one or the other)

- take out any other items if there plugged into the motherboard e.g sound card wifi card (just essentials gpu) if you have on-board graphics even better try that !

- take the system apart and build it on the motherboard box or any cardboard box in case the case is shorting things out! it sometimes happens. if she boots check motherboard standoffs and re-install

- make sure the CPU is compatible with the motherboard (check the manufacturer website for this cpu support list)

-make sure the ram is also compatible

-check the power supply as a last resort if you have a spare.

-if you have tried all these steps i would say test the GPU in another system visa versa
