What happened? (system suddenly dead)

Hi all,

I'm wondering if anyone can diagnose this problem. I can only guess as to the cause.

Basically I have an Athlon XP 2000 system on an Nforce2 Biostar M7NCD Pro system board. (never overclocked) System has been running fine for over a year.

I'm using it the other night just fine browsing the web. All of a sudden the system resets totally randomly. It then started to reboot as it normally does EXCEPT when it was loading Win XP the status blocks were moving across as usual but hard froze before fully loading.

At that point I turned off the system and waited a few seconds. I then turned it back on only to have the monitor not come on and for the system to repeat a single beep every few seconds.

I tested the RAM and AGP card (radeon 9700) in another system. Worked fine. I removed all the PCI cards. Same beep.

I tried to clear the CMOS with the jumper as well. Still nothing.

Best I can figure is for some reason either the CPU or system board (the only two components I didn't test on a different system) died after over a year of no problems.

Am I right in this conclusion? If so, what could have possibly caused this to happen? I've never experienced something like this before. It was totally random and unusual.
 
I don't think it's the AGP card. It has worked fine in this system previously, and when put in another system works fine still.
 
well if it isnt your ram or your video card, i would do the following. unplug all drives, unplu powerf rom all drives ( just to rule out over load on psu )
power on again ( obv with ram and g card in of course )
if stil beeping at you, might be worth testing your cpu elsewhere. ws there any burning smell, when it first went dodgy? also does fan still go on hsf? and if u remove HSF, is there any scorche marks arund the die or under the other side of the organic substrateof the athlon cpu?

You could try to plug in the another hard drive into the system that you are having problems with. Although I don't think it's your hard drive that is dying, it could be worth a shot to see what happens. Have you installed anything on the computer recently? IF you haven't, try formatting the hard drive (if you don't have anything too imporant that you don't want to lose). If you have stuff that you don't want to lose, you can remove the hard drive and boot up windows XP pro on another computer but first plug in power into the hard drive that you are using for your OS now. After the computer boots up with power already have been on the hard drive, plug in the IDE or serial cable not sure what type you're using. You can back up your stuff that way. If it were your processor, your computer would not boot at all. You would just hear beeping on the motherboard. Well good luck

No PSU has nothing to do with it. If he were having PSU troubles than his system wouldn't post properly.

Have you tried to reinstall.

Also what are your Case and CPU temps. Make sure all fans are still spinning. What is the ambient room temp? This sounds heat or HDD related.

Um.. Guys. How are you going to reinstall Windows if the motherboard doesn't even POST? It's not going to be temps if it doesn't even post, and another hard drive isn't going to do squat as the board should still post if it has NO hard drive in it.

The one beep every so many seconds is a memory beep on that board. The memory worked in this board before, and works in another motherboard, so it can be concluded that the motherboard has died.

Which is surprising since Biostar is typically a fairly durable motherboard.
 
Oh jeez i misread i thought it was still stuck at the Windows Loading Screen. Yeah i agree with Jonny you probably have a dead M/B or Processor.

Probably not a dead processor. I've yet to hear a motherboard beep when the processor dead. When the processor is overheating, sure. But not dead. And the beep doesn't sound like a thermal warning beep.
