CPU or Motherboard

[ZonationX]

I recently built a computer and it will not boot. I have tried several video sources and nothing changes. I think it is either the cpu or the motherboard but I would appreciate a second opinion on what it could be. Any help would be appreciated.

CPU: AMD FX 8core 3.0Ghz
Motherboard: Asus M5A88-V
VideoCard: XFX R7870 Black Edition
Ram: 4x 2GB DDR3 1333 G-SKILL RipJaws (From previous build)
Power Supply: CoolerMaster M2 SilentPro 620W
Hard Drive: 750GB Wetern Digital Caviar Black
Case: Antec 300

Which FX model is it? Anyways it could be that bios needs updating. Are you sure it will not post or will it not boot at all? If it will not boot then check the front panel connectors.

What were your previous build?

Probably the motherboard - just cause it has the socket doesn't mean it supports the processor.

I believe the motherboard has the socket and is compatible with the FX processors.

Take a look at this:

All the FX series is listed in there. All the FX series needs is a bios update since the board was released before the release of the FX processors.

I tried to put my quad (Phenom II X4) in the mobo, and the same result happened.

No post, no bios.

No post, no bios.

Does the power button even respond? Like any fans moving or anything like that? Monitor signal? Anything?

Yes, all fans move all lights on everything works it seems, just no post/bios.

How is your monitor connected to this baby?

I know this answer wont please you but it would be best if you go through this checklist:

It tells you most things that cause that issue. If none of this works out then I would believe the motherboard to be at fault, CPUs rarely do die.

check that all the standoff were uses so that the mb not shorting out. also check that the i\o shield and cpu cooler not shorting anything out. also check that you have the 4/8 pin power plug connected and all the power plugs on the video card are connected. if your cpu/mb has onboard video try seeing if that posting. one thing to check is that the mb header wires are on right.
