A7V8X-X Restarting???

First off I would like to apologize for not posting this in the motherboards forum. For some reason I could not get the page to load. Go figure.

The mobo is running Althlon 2400+ with 512 (2x 256) DDR400
Radeon 9200.

The computer runs perfectly fine under full load and idle, but for some reason it restarts. It can run for a day or an hour and it will spontaniously restart. I went to google forums and it turn out that a lot of people are having this same problem. I went to the Asus website and I looked at the Bios updates. None of them seemd to address the problem, What should I do? I may be mistaken on the bios updates considering I dont realy know what to look for. An dif I was to update the bios, will the new bios over-run or undo the previous changes from other versions or will it include those aswell?

Thanks

Spontaneous, non enforced reboots can point to a few things worth checking out
1) PSU trouble. Check voltages in Bios
2) bad memory/too agressive memory timings. Run memtest86
3) northbridge overheating. Check if its hot, if it is, try adding some cooling to it
4) motherboard dying, check for expanding/leaking capacitors.

Do you have mbm5? Set it up in syslog & interval, to keep a running log at 5 minute intervals. This will give you a copy of your temps, volts etc. just before the crash. It sounds like a heat problem, but voltage spikes could be your problem as well.

Thanks for the help. Ill look into all of these. One question though, Does the mobo support 400fsb processors? It supports the ram, but why wouldnt it?

It would need to have a 6:2:1 divider for fsb:agp:p ci. At 200 fsb your agp would be at 80 and your pci would be at 40, instead of 66 and 33.

I had that problem with my MVP3 chipset board, allong with spontanious data loss, etc. But all those problems were eventually fixed after 2 years of BIOS updates and driver updates, with no hardware changes. The thing still refused to configure more than 3 bus mastering cards...

Nothing wrong with your BIOS settings for that Motherboard I own one and that board aside from having an 8X AGP buss is very simple to use plug and play basics.

Sounds like you have one of two problems the first one is overheating the second one is your power supply has a bad channel on it.

You will want to remove the heat sink and correctly re-do the thermal paste a thin film that covers only the DIE.
If you have to remove the old stuff use many cue-tips dry until you have 95% of the paste cleaned up then use some standard nail polish on the cue-tips just enough to moisten the tip and rub the rest of the paste off. After put a thin coat of new thermal paste on the die make sure you cover the top of the die completely. You do not need to put any on the bottom of the heat-sink so clean it completely.

If your PC keeps randomly restarting after that then try to use a different power supply at least a 350 Watt unit minimum for that MoB.

60C is overheating? Thats what ASUS probe reads. But I heard that Probe mesures the socket temp and not the cpu temp. What programs can I use to find the real temp? I had one that I could not figure out how to install. Darn it, I forgot the name. Im doing real good here.

I appreciate the help. Thanks

Before you try another PSU, do you have the "automatic reboot on error" option activated? I don't know wich Windows version you have but I think the option is checked by default on Windows 2000 and XP. If it is, uncheck it, wait for a blue screen and that will probably give you a clue to where the problem is. Another way to get some info after a problem is to look at the event viewer.

Hope that helps!

Asus probe may not be very accurate. The best program to use is mbm5 (google for it). You have to adjust the readings (calibrate it) in settings. You should set it up to keep a running log.
60c is too low to cause crashing, usually, while Intel says you may encounter instability above 65c.
