  Athlon 2000+ Random Reboot

I have an Athlon XP 2000+ on a Gigabyte GA7DXE motherboard which consistently reboots. There is no pattern that I can see. Running board diagnostics I get reports that the 12V is nearly at max load (13V) and that the processor temp can be anywhere between 60 and 75 degrees.

Since the processor temp drops whilst running I am fairly sure it isnt a temperature issue and wondered if it could be a temporary increased load on the 12v which is stalling other devices - hence the reason the dump files are not consistent. Current PSU is 300W.

If the voltage is higher than 12 V I wouldn't worry about it. If your system was loaded down, the Voltage would drop (to much current draw) and your system would fail then. You may have a wiring problem though. I once had bare wire showing in my case from a broken fan wire, and when it touched the case, the computer would reboot. So what you could do is trace each wire from the power supply and make sure no bare wire is showing. Has the computer always done it, or has it just started?

This has occurred since Day 1 over 2 months ago! Originally locking up due to incompatible graphics card but that was soon sorted. Now it is completley random as to the cause. All wires are fine by the way.

Forgot to mention - there is also a 1-2mm clearance via four rubber feet between the heatsink and the processor. first time ive seen that on a processor so is that right for this one?

You mentioned your PSU is 300W. I feel that could be the problem. At times some of these crapy PSUs don't give what they say. Even though it says 300W, don't be surprised if it is much less than that. I suggest going for an Antec true-power PSU...I feel changing the PSU might solve the problem.

Re the rubber pads on the CPU this is normal. Ensure you used Thermal Compound on the chip, ie; between the chip and the heatsink, to prevent CPU overheating. Make sure the fan and heatsink is up to the job too.
This cured a similar problem of mine in the past.
I think 300w PSU should be ok unless you have loads of hardware running, but is something to consider.
Good luck

OK, some good news to report - After removing the board controlled case fan and moving a PCI card from one slot to another, the system seems at present to have not failed (rebuilt yesterday morning).

I'm fairly happy especially since the system temp and processor temp have settled to a lower range.

So, final question in all of this is what is thermal compund - pad/gel etc and from where can I get some - actual addresses please since web searches have proved unfruitful. Hopefully this will then make the heatsink run more efficiently.

Thanks for all the help guys.

We are happy to know that your system stabilized. As for the info about thermal compound and pads/gel...thermal paste is just a paste that is applied between the cpu and the heatsink to improve the thermal conductivity so that maximum heat is lost. The best thermal compound I have so far come across is the arctic silver compound...and you can find more info about it here:
http://www.arcticsilver.com/as3.htm
This compound is easily available and works well, however be carefull as there are lots of counterfeits in the market that claim to be arctic silver but don't work as well..their website mentions this.
One thing to take care of while using a thermal compund is that you should be carefull to apply just the right amount...too much and you might run in to problems.
As for the thermal pads, they do the same job as the paste but are simpler to apply...however I personally don't like them.
Anyway if you want more info on this you can read the article by Sander here:

Thermal Compound now applied and a processor which used to run in the 70's now runs at 45-50 degrees. Thanks again everyone - I know it seems excessive thanks but I have been so stressed out with this PC - it was a reward to myself for having quit smoking for 6 months! Oh the irony that the inherent stress would have previously warranted a few smokes!!!
