Missing boot-sequence

[Aggesut]

Evening,


I decided to revive my older computer with some new hardware.

I've changed the Motherboard, CPU, PSU and Graphics Card, and all of it has been changed at the same time. Now I have a problem; Basically the computer isn't booting.

What happens is; I turn on the computer, fans on psu, graphics card and others are running, but I'm not getting a boot-beep, nothing happens on the screen and the keyboard doesn't turn on.

I've tried to restart the CLRTC-battery, but nothing changed.

Am I missing something, or am I just being an unlucky bastard?



ps: I've had a look at the post below this one by Corbit, but there's nothing that helps.



The hardware is as follow:
PSU: 500W
Motherboard: Asus P5Q Deluxe
CPU: Intel 2.4 2-quad
Graphics card: Radeon HD4770
Ram: 1024, PC2 6400


Thanks for your interest.

Assuming the motherboard is connected to a speaker, then the lack of any beeping would suggested the motherboard hasn't initialised at all.

The BIOS on the motherboard, which is started before anything else, controls the diagnostic beeps.

The various fans will run, even if the rest of the system is dead, so long as they're getting power from the PSU.

I'd try starting the board with a different PSU, and if it still does nothing, then send the board back.

Yep. What he said. No beeps and fans run is a sure sign of a dead board or even possible a short on the back of the board from a standoff.

Thanks for your answers.

I've just tried with a different Motherboard to see if it changed anything. I also tried with a different PSU just to see if anything changed. I might be amazingly unlucky, but nothing changed, ie. either both motherboards are dead or there's something else. I've also been through the system panel connector, just to see if any was plugged in wrong. Nothing there either.

I could try and get a new motherboard and have a test, but it's puzzling me that both motherboards should be dead.

Is there anything else that could give the same symptoms?

Have you tried to test the board out of the box with just the Ram and CPU and Video card installed?

So what haven't you swapped, cpu video and ram? Can you try with just one DIMM installed, and do you have another CPU to test? If it's the Q6600, which I believe it is, that should be fine for any P45 board so doubt it's a BIOS issue.

Do you have another cpu, another video card? Maybe another stick of RAM? Does your ram require a higher voltage than the stock 1.8?

This is your best bet-even better if you put the board on a bench, out of the case. Just CPU and 1 stick of memory.

Alright, thanks everyone for your responses and answers, it's appreciated.

Thanks to Occam's Razor my computer now works. I decided to take everything apart and reset the battery. I also did a test on my Ram blocks, and one was defect.

We'll see if everything works as it should after i've done some tests, and once again, thanks for your answers, it's appreciated

Occam's Razor is very useful so often! Shame I forget about it half the time.
