No POST Beep. System Dead.

alchemistkevin · 9 Nov 2010 at 12:53

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

a full list of parts please?

so your using onboard gpu? i would first suggest clearing the CMOS, by turning off the power and pulling the battery from the board for a minute.

try one stick of ram? then try another in different slots.

couple of DVD drives (Samsung), HDD (not sure, Samsung probably), 4GB RAM (Kingston, I think) sound/video is onboard on the Gigabyte board.

All I'm trying to do is to get a POST beep. I understand, just the inserting the CPU in the board, connecting the tiny speaker and powering it should produce a beep (or two)

if you managed to borrow a P45 board, can you borrow a cpu?

No

Hence this post.

going to be difficult without testing other bits.

yes you're right but would this be a safe assumption that the same if the same CPU is used on two boards and there's no POST beep, its probably the CPU that's at fault?

What happens if we just try and power the motherboard, without anything on it - does it POST?

I had this issue when trying to fit an AM3 CPU to an AM2 (unsupporting) board

No beeps with or without the CPU so I have to go with the CPU is at fault...
