Is it my cpu or is it my motherboard

[huanwu26]

Hi

When I first built my computer I booted up to nothing appeared on the screen and no POST, so I though my mobo fried but I took out my two ram (I had already two for my old stock computer) and video card. Then it said that I had a incompatible CPU and shutdown in few secs. I don't know whether it is my mobo or my cpu? help me!!!

Specs:
MOBO: N-Alvorix-RS880-uATX (Alvorix)
Memory:Team Elite 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10600)
GPU: XFX Double D FX-787A-CDFC Radeon HD 7870
case: NXZT gamma classic

It says here that the CPU is compatible. I would make sure you haven't bent any pins or anything like that when installing it.

You might also want to search and see if this board requires a bios update when switching to your particular CPU.

The processor might only be compatible after a BIOS update

Check the BIOS you have , and for any updates that are available

When you put the 7870 in there, was the PSU changed or is it the stock PSU? What's the reported wattage of your PSU?
