[Product Information] Product Type : Motherboard Product Model : M3N78 Pro Product S/N : 88moac821834 Date of Purchase : 2007/06/01 [Motherboard Specification] Motherboard Revision : 0386 Motherboard BIOS Revision : 1404 [VGA Card Specification] VGA Card Vendor : nVidia VGA Card Model : GeForce 9800GT VGA Card Chipset : GeForce VGA Card Driver : 126.96.36.19938 [CPU Specification] CPU Vendor : AMD CPU Type : Phenom 8650 CPU Speed : 2.3G [Memory Specification] Memory Vendor : Kingston Memory Model : KHX8500AD2/2GR Memory Capacity : 2G [HDD Specification] [Add-on Card Specificatio] Operating System : Vista 32bit [Problem Description] Computer is freezing after ~20 minutes of uptime with minimum load. Temperature probe indicates "Temp3" is >=127C. I believe this is the onboard graphics accelerator temperature (confirmed that the heat sink is very hot, Temp3 comes down when compressed air is blown on it). Onboard graphics should be disabled as I have a PCI-X video card that is working perfectly. BIOS is up to date, chipset drivers are up to date.Well, probably some of that information is superfluous, but more rigor is better than less, right? I outlined the problem with a high degree of specificity, let's see what they think.
Thank you for contacting ASUS technical support.
We regret the inconvenience.
I understand the issue. I will certianly help you out.
1. Check the memory: Verify the memory by using a memory checker. Verify that each memory chip is the same speed and that it is configured correctly in the system.
2. Power supply: Make sure that the power supply has enough wattage to appropriately handle the installed devices. If you added memory, installed a newer processor, installed additional drives, or added external devices, such devices can require more energy than the current power supply can provide consistently.
3. Defaults: Reset the system back to the system defaults to see whether the issues occur when the system is running in its default configuration.
4. Do you see any Stop error BugcheckCode in the event data when the computer restarts?
5. Check Event viewer for any errors:
Open Event Viewer by clicking the Start button, clicking Control Panel, clicking System and Security, clicking Administrative Tools, and then double-clicking Event Viewer.? If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
6. Also check the cooling system of the PC and heat sinks in the PC.
Feel free to contact for further queries.

My ram chips are the same make/model/speed/all that. Windows memory diagnostic tool just completed with no errors.
>2. Power supply
I'm not sure the best way to do this (test voltage?), but the eXtreme power supply calculator (which lists all of my hardware) puts my wattage demand at 277W. I am using a 650W power supply so I hope that is sufficient.
> 3. Defaults: Reset the system back to the system defaults to see whether the issues occur when the system is running in its default configuration.
Which defaults are we talking about here? BIOS defaults? Reinstall Windows? Yank all the hardware? This is a pretty disruptive activity so I'd like to go in with at least some confidence that it'll solve the problem.
I can say this problem has survived a Windows reinstall three months ago.
> 4. Do you see any Stop error BugcheckCode in the event data when the computer restarts?
You mean a BSOD text? When it crashes the display just locks on whatever's in the buffer and I have to do a hard reset. So, no obvious Windows errors here.
> 5. Check Event viewer for any errors:
The Windows system logs don't have anything alarming - except for the crit-level "Computer failed to shut down properly" that is associated with the reboot after crash. It's mostly windows media player sharing/networking messages.

Yeah, as I stated I kinda think this is the problem. The thermo app indicates the CPU is just fine, the fan is running and heat sink is warm but not hot. Same deal for the PCI-X card/temperature/fan.
In contrast, the heat sink on the onboard GPU is very hot to touch. The temperature reading for it maxes out the 8 bit value and I'm inclined to believe this is not erroneous because it climbs steadily to 127C and will drop below when sprayed with compressed air.
Shouldn't this core be turned off/low power with a PCI-X graphics card present (and not in VGA mode and whatever)?
Even if it's running at full clock, should it be operating at >100C with the stock heat sink (the one with the ASUS logo on it!).
If, by chance, the crash is unassociated, is it okay that this device is running so hot?

Please allow me to assist you in troubleshooting your unit.
In this case, I request you to try removing the graphics card from the board and try boot with the on board graphics and check if any issue presist.
Then, regarding the freezing I request you to try with the different hard drive and the OS if you are facing the same issue.
This issue may cause due to RAM also. So try boot with the minimum RAM on the board.
If you need any further assistance please feel free to contact us anytime.
> In this case, I request you to try removing the graphics card from the board and try boot with the on board graphics and check if any issue presist.
I did this, Windows performed a driver install for the onboard graphics device, which is strange because I would have thought this would be included in the chipset drivers.
There was a slight difference in behavior, in that 'Temp3' did not remain pegged at 127C but instead bounced around between 50C and 127C, however it spent most of its time above 100C. But, as usual, over ~30 minutes the other temperatures started coming up and the display froze.
> Then, regarding the freezing I request you to try with the different hard drive and the OS if you are facing the same issue.
You want me to buy a new hard drive and install a new copy of Windows on it? This seems like a heavy-handed approach.
> This issue may cause due to RAM also. So try boot with the minimum RAM on the board.
I tried each of my ram sticks individually, same result. Of course, either of them could have bad blocks and these bad blocks could have escaped the memory checker, but I think other avenues are more likely.
You seem to be providing a generic Windows crash diagnostic workflow, which I appreciate, but seems to be ignoring an obvious symptom. I contacted you guys because hardware on the motherboard seemed to be operating outside of spec. If we can determine that this is not the case then I can proceed looking at other system components on my own. So I'll repeat my above questions:
- Shouldn't the onboard gpu be turned off/low power with a PCI-X graphics card present?
- Even if it's running at full clock, should it be operating at >100C with the stock heat sink?
- If, by chance, the crash is unassociated, is it okay that this device is running so hot, i.e. what does the spec say on operating temps? (My web search yielded nothing).
I'm sorry you've had such a bad experience. I'd like to try and help.
I really appreciate your efforts in trying to resolving the issue.
Please note that, the maximum temprature should be 55C.
I suggest that, it may be the hardware issue with your motherboard. So, We will process RMA for the motherboard.
