Question about Intel DG31PR Motherboard

Ethernet card disappears on DG31PR motherboard


I have 60 of the Intel DG31PR motherboards that I got back in November for an upgrade. I have had a lot of problems with these computers losing their network cards in the OS. I am running Windows XP SP3 and all current Windows updates installed. The computers will boot up fine with no errors and then I get phone calls saying that people cannot get out to the internet or to our document server. I have to go shut the computer off and then unplug the power cord from the back of the computer. Most of the time the network card will just reappear after I do that. Sometimes it takes more than one try. I downloaded the newest driver off Intel's site and that has not made any difference. All 60 of the computers have identical hardware. Has anyone else had this problem?

    I've been using these mobo's for about 1 year now and have had this happen 4 times in the last 2 months. Can't pin-point it. NIC just dissappears in the device manager. Only solution I've found was to add PCI NIC.

    The vendor we purchased all of our computers from contacted Intel and they are aware of this problem. They believe it is just a certain AA revision that is having the problem. The revision's that we have are AA D97573 - 301 and 302. They said that you can try to set the network card from auto negotiate to either 100 mbps or 1 gb and that it may help the problem. They also told our vendor that they are working on but do not have a timetable for an official fix but it would likely be in the form of either a bios update or a network card driver update.

    i did what gurneyhack suggested and rolled back my LAN driver and it now works fine. my driver is version: 5.664.205.2007 date: 3/16/2007.

    i got the driver from my DG31PR cd that came with the board. i could not find an older driver like this one on the intel website.

    I have not had this problem with these mobo's but if the problem is so consistent, the company you're at must pay you to fix them...once, and wonder why they are not fixed when you told them it was. Have you tried to cut down on resolving this problem with the use of a NIC other than the on-board one? With all the time you spend trying to fix them, a trip to e-bay for a lot of NIC's may be in order to just fix the problem and move on to other neglected issues. I looked thru the Intel DB and found nothing in their FAQ's about this problem, however you may want to try this link:

We have many boards in the field and have seen this issue 3 times in the last several weeks. The solution we have developed is to disable the NIC in the BIOS the boot into Windows. Shutdown again and boot back into the BIOS and reenable NIC (All this is just to get the NIC to appear again in Device Manager). Also, we are pulling the power cord before starting the computer again.

Once we have done that and have the NIC visible in Device Manager we are rolling back the driver to the one dated 8/6/2008 with version number 5.702.806.2008

Does the DG31PR motherboard support Geforce 8400GS 512MB PCI-E?

Yes, but check your BIOS and make sure the PCI-E slot is enabled.

Also, when you say doesn't start, you mean just the screen? Right?

Can i put a 9800 gtx+ on a dg31pr motherboard?

OK, Here you are . Your present card ,8500GTdraws approximately 40 watts. Your proposed card draws approximately 150 watts according to a review I just read on it.  A 400 watt is not very much and if you get close to maxing out you run the risk of a low voltage problem which could and will burn out compoinents.  I would not do it.    Also , if you upgrade power supply, know that the wattage given is usually peak , not operating wattage which can be as much as 10 or more percent less. Go for at least 600.
