No POST Beep. System Dead.

[alchemistkevin]

Hi,

I had a working system until 2 days ago when I tried to install the nvidia HDMI audio driver & restarted it.

It hung on the Windows logo while starting up and I had to force a cold reboot, since then, there's no POST beeps, no video (HDMI or DVI), no lights (apart from the power light), nothing.

The PSU & the CPU fans come on and that's it.

I have a Quad Core processor and a Gigabyte GA-73PVM-S2H board. Stock cooler.


Yesterday I got a P45 mothboard from a mate and put the CPU on it to see what had fried (the CPU or my motherboard) and again no beeps - I don't have an external video card so I can't be sure if the POST screen comes up but I would at least expect a POST beep.

Would I be correct in identifying the CPU as dead and asking Intel for a replacement or can I simulate further tests?

Sorry for a long post and thanks for reading - any help would be appreciated

Did you just swap the motherboard, or did you also try a different PSU, GPU and RAM?

From experience of something virtually identical a couple of months back i`d start with swapping in a different GPU. Was my problem and a new card later all is well again.

Just swapped the motherboard. I haven't got a GPU, tried booting with and without RAM - no beeps.

I haven't got a GPU - video is onboard on the gigabyte and I tried starting via the MSI p45 board without video (just to hear if there's a POST beep)
