Boot failure HDD light stays on

by Winney123 / February 17, 2009 8:27 PM PST

Hi Everyone, hope someone can help with this problem. I have a self built PC which has been running fine for about 2 years now. When I went to boot up this morning the hdd light stays on, all the fans (case, CPU, graphics card, and PSU) spin up. The power light on the front of the case does not come on but the small LED on the motherboard does.I get no output to the display or boot sequence at all!! Recently it has failed to shut down properly a few times (the power light and fans continue) but output to the display etc stop. Things I have tried; resetting the CMOS, changing the CMOS battery, unplugging the RAM and moved to different slots, unplugging graphics card (makes a continuous beep when I do that)!! Even tried unplugging the CD Rom, Floppy drive, hdd, graphics card and RAM but to no avail.Guess its one of these, PSU, Motherboard, CPU or RAM.
Asus A8N-32 Sli Deluxe motherboard.
AMD 4400 Dual Core CPU
Seasonic 600w power supply
Corsair CMX1024-3500LL Pro RAM 2 sticks
MSI NX8800 Ultra OC Graphics Card
OS Windows XP x 64
Hope someone can help me on this,

The beep test.

I didn't read if the machine beeped at power up. Better than 99% do and yours doesn't.

Beep test.

Power supply.
Motherboard speaker.

Just 4 parts and if it doesn't beep then we are looking at what parts are likely faulty.

Thanks Bob for the quick reply,
As for the beep test, I just tried it, removed all cables, RAM etc, and tried it with just the 4 parts and it gives one continuous beep (very loud tone,neighbour waking loud!!) The tone stops if I plug in the graphics card though. Also forgot to mention my RAM has those little lights on top but they dont come on (didnt have in for the beep test though)My PC has never beeped when starting coincidentally even when it was working fine.

Forgot to ask, do I need to physically remove the graphics card from the PCI express slot on the motherboard or just all the power connectors?

Yes, the PCIE card must be unplugged.

Here's the BEEP test part 2.

If we are getting beeps, even if a long one that's a good sign that the motherboard and CPU might be ok. The speaker certain is good!

Now we add just one part. When the beeps stop, we power down and remove that part and put it on the suspect pile of parts.

This is where having some spare parts really pays off.

In closing, if you ever overtaxed the power supply then it becomes a factor.

Okay, will try connecting pieces one by one. Is there a good order to this? I know the beep stops if I connect the Graphics card and have a spare one lying around but not a spare PSU etc.

Your choice.

I usually skip cards like audio, lan, wifi since I want to see a video display so I can see the BIOS, etc.

Thanks Bob, went to get the PSU tested and found it was a dud. Plugged in and now have a power light front panel and plugged in RAM (sorry hadnt seen your post) and it is lighting up so hope when I install other cards it will be up and running again. Wish me luck, will let you know!!
PS Living in Tokyo makes stuff like this twice as hard!!
