Hi all.

As the title suggest, I need your help!

Had a power cut early yesterday morning and since then, my pc won't boot.

And I mean nothing, no fans, no beeps, nothing. The only signs of life are the green LED on the motherboard and, strangely, all three keyboard lights on permanently.

First thing I though of was motherboard failure, which in this case is a Asus P5N32-E SLI.

Anyway, it just so happens that I have a spare P5N32-E SLI here which is brand new. But after swapping the CPU, memory and graphics card, it still refuses to do anything?

The only difference between the two boards is that the keyboard lights don't come on with the new board.

So, after this, I borrowed a PSU which changed nothing. I have since tested the RAM in another PC which seemed to work fine.

I also tested the Graphics card, a 8800 GT, which worked except for making a beeping sound from the case speaker. I thought this might be the fact that the pc didn't have a 6 pin power adaptor so the card was running without?

Finally, I tested with just the CPU install with the case speaker plugged in and still nothing.

I did the wire test with my PSU by bridging the gap between the green and black wires and it seemed to power my hard drives fine.

Anyway, I am now at a loss as to what to do? Also, I am worried that maybe my PSU damaged both motherboards?

Any suggestions would be greatly appreciated.


BTW, pc specs are:

C2D E6400
Asus P5N32-E SLi
2 x 1Gb Geil PC6400
2 x 2gb Cosair PC6400
XFX 8800GT 320mb
Enermax 500 Watt PSU
 
Wow, that was a quick response. :)

Hmm, I guess there is no way of testing that without getting a replacement.

Although I thought it was very rare for CPU's to fry?

Thanks.
 
It is very unfair! :)

Still, thanks for the heads up.

Looks like I might have a completely different motherboard and CPU to try tomorrow. If that doesn't fix it, then I am going to start going mad!

Should I be worried though about my PSU potentially causing damage to this new motherboard?
 
I'm sorry, but I am a little out of touch.

I didn't know there were different kinds of PSU that protect components?

Also, are you saying that I shouldn't use my current PSU in case it does damage the new board?

Sorry to be a pain, but like I have already mentioned, it has been a while since I have done anything like this and I am a bit rusty.

Thanks.
 
No Bios on either motherboard or PSU. Basically, on the first motherboard, the LED on the board itself and the keyboard lights are the only things that work. Monitor is not triggered and the fans don't start.

On second board it is exactly the same except the keyboard doesn't light up.

Hope that clears it up.

Sorry for any confusion.
 
Just a quick update to let you guys know that, as usual, you were spot on. :)

Got a new CPU and board and it is working fine. So it appears that I might have fried a CPU after all.

As for what you suggest Howiepoohs, the PSU is fine for now, but I agree that it might be a little suspect , so I will probably get it swapped out soon.

Still keeping fingers crossed that it will continue to work. :)

Thanks very much for all your help.

Not a problem, glad I could help. Sorry about the processor that's annoying. I would look for a good surge protector socket just in case, they are not too dear. They plug in the wall socket and you plug your PC power lead into it.

Already gone and bought one :)

Thanks again.
