My computer flaked on me a few days ago. It seems to be either cpu or motherboard although it is possible it is hard drive. I was playing an on-line first person shooter. When the map changed the comp died. I assume it was a heat issue of some sort. Either that or just a huge coincidence as I had not played any games in weeks, maybe months. Then the comp died after this session. On the other hand I used to play the same game (day of defeat-a W.W.II shooter/hl mod) on it all the time so perhaps it is merely a coincidence. Also of note it was at night and the ambient room temperature was not hot at all. The beep code is kind of a continuous pulsing beep perhaps the cpu overheating mentioned here?

I've tried plugging it in and turning it on and off several times, letting it sit for a while and doing the same again, disconnecting both floppy and cd rom, switching video cards and changing memory, and I still get nothing. The system doesn't even post. It just runs and makes the pulsing beep when I turn it on. Since the motherboard is a bargain motherboard and presumably the weakest link I think I'll simply replace the mobo with the money that it would take to have the system bench tested.

<font color=red>The sort of "house favorite" for the amd athlon xp was an abit board, NF7-S, I think it was back when I built this system last year. Is that still the board people would recommend?</font color=red>

The cpu is the amd mobile athlon xp 2600. The hdd is a western digital 40 gig. The motherboard is an iwill k7s3. All three of these components were purchased new last spring. I had some newbie troubles getting the system set up but once I got it going it has been a rock solid system up until this point. My assumption is I have fried either the cpu or the mobo somehow. The system should boot to post without any drives attached, correct? I think I tried disconnecting the hard drive as well and still got nothing.

I did have the cpu temp set to shutdown at a certain temp but if that were what had happened I would assume it would boot back up after it cooled. I'm going to try clearing the cmos jumper and restarting. If that doesn't work I may also try removing and reinstalling the cpu with fresh arctic silver. It would be great it if were a no expense fix.:>)

It doesnt' have to be the motherboard. NF7 or NF7-S are fine boards.

Any way for you to test a graphics card? Borrow one from a friend?

Any way for you to test your PSU? Borrow one from a friend?

Are you sure you have and "Award Bios" ???

Other Bios beep codes are on previous pages of the same article.

Flinx: He did say that he swapped vid cards.

Zeek: Have you tried clearing the CMOS? You can do that by removing the round Lithium battery for about 5 mins and then reinsert and start comp. Unplug the power to the comp when you do this...

I'm going to try that (the cmos clear you suggested) next. I got sidetracked last night and didn't get around to it. It would be great if it was a simple fix like that. This inexpensive little system has served me well up until this point.

The power supply appears to be running I just get no screen, no boot to post and an ugly pulsing beep instead of the nice friendly "everything is fine" single beep.

That is a good idea about checking the bios too. I forgot to look in the book and make sure it was an award bios.

If clearing the cmos doesn't work and I don't find any other clues on the beep codes I'll switch out the psu just to be sure. It is a nice psu though, an antec 430 true power also purchased new last spring. It cost me around $100 at best buy. I've learned the hard way that it is worth buying a good power supply.

Thanks for all the good suggestions, guys.

Tried removing cmos battery.- no dice
Tried another power supply unit.- no dice
It is award bios--I assume the alarm code is cpu hot but I'm really not sure. I'm pretty much down to either cpu or mainboard as I have also switched out the memory.
Thanks again.

Are you sure the HSF is properly mounted and <i>clean</i>. Lots of dust really reduces hsf efficiency and can reduce air circulation in the case if covering the case fans. You may want to use some compressed air to really clean out the case. Are you sure that the fan is spinning on the HSF?

Have you checked for <A HREF="http://www.motherboardrepair.com/index.php?sec=images" target="_new">Bad capacitors</A>? Won't give you that beep, but something you should check for when having probs.

Don't you mean the Abit NF7-S v2.0? The S2 is a different board...
