[Dalik11]

Hello

Recently I changed my CPU and now when I try to turn on my PC everything starts as always but now after about 5 sec running Red VGA Led comes on on the motherboard and after few more seconds the PC turns off and I dont get any Display at all Monitor does not even power up

I tried to switch back to the old CPU
Restarted the CMOS
Checked every cable every connection
Reseat the GPU

Update: Tried to use brothers GPU r9 380 ( Not sure ) but still the same problem

None of it helped
Any ideas what should I do next?

CPU - Fx8320 or Fx9590
Mobo- Asus crosshair V formula ( Not Z )
GPU - FXF amd r9 290x

You're saying you upgraded the CPU to an FX-9590? Your board "Supports CPU up to 140 W." The FX-9590 is a 220W CPU. Your mobo's VRM could be damaged. :\

Good point...

Putting in a 220W CPU should not damage a board since it shouldnt be pulling that amount of power during POST, or boot up. You have to really load that thing in order to drive power consumption anywhere near 200W. I know for a fact that Intel CPUs work that way. But given the ineptness of AMD, who knows maybe they do pull 200W during POST.
