Hello,

                 As you have said your system is being used as workstation.Then first of all you should consider number of users to whom your system serves and then conclude the load which is resulting or not and also you should look forward to Intel Upcomping BIOS updates.I think this could be the reason and also check out your processor's compatibilty with board.In most of cases this could be the issue.

Hello,

         If you have configure any BIOS setting then rebooting could be the result of those settings.Secondly i've seen similar issues and i'm also advising if you using those components like RAM, PRoc and PowerSupply.Then check their compatibility with board so that you can assured  whether you're using right parts or not.

Adeel,

Can I ask if you are an Intel employee or representative of some kind?  I must admit that your contributions to this thread so far have been confusing at best, and seem to suggest that the problems many are having with this board are self-induced.

Hello,

Did you try re-seating the RAM??  I re-seated the RAM and switched it around and so far i am having no problems.  From what i have been reading and what i have experienced on my own this would seem to be some type of memory problem or the memory slots on the motherboard.  Either the slots have issues (possible manufacture defect) or RAM needs to be seated perfectly.  Keep us posted!!!

Hello,

         No, im not representative actually i have experienced several issues with Intel boards and i'm usin them since four years so that i can make conclusions

and i think pref_AMD is not agreed with my suggestions, might be he's right.I'm just sorting out the whole condition and check out how's my experience and o'm also trying to be  Intel's representive nowadays.

I got confirmation today that the Intel engineers are watching this thread and are trying to replicate the problem. Just to complicate things a bit more, I'm not running Vista, I'm using 7 RC.

Now before anyone starts pointing fingers at 7; a bit of background. I've been using 7 since Beta, when it first got released to MS Partners. At that time I was using a Gigabyte 965P-DQ6 and had no issues whatsoever. I then installed RC once it was launched and still had no problems. I purchased the DP45SG, did a clean install and my problems started. The Gigabyte board is still in use, still running 7 RC, fully up to date, same software as before and as stable as anything. 

Anyway, back to the "troublesome" board. At first the system would lock up/hang once or twice a day. Then the random "resets" started. Some days it didn't hang or reset and other it did, 4 or 5 times per day. I never had any of the same apps open in the foreground when it happened. I must say that every time it's done it (while I was working on the system) was when I either just move or click the mouse or at exactly the same time that I press a key on the keyboard. I've even considered that it could be faulty USB ports as all my devices are USB but then that wouldn't explain the resetting when unattended. I will actually remove ALL USB devices and change the k/m to PS2 just to make 100% sure (as soon as I finish this very long winded post)

I had HUGE problems trying to flash the BIOS as the machine would "hang" as soon as it restarted (before starting with flash process). It took me nearly 2 days to try flash the BIOS from version 83 to anything after. Eventually I used the Intel integrators toolkit and made a "custom BIOS" so to speak. I automated the entire process by using a bootable USB Flash Drive. Once I got the BIOS updated to 116, I re-flashed to the "standard" 116 when the random resets persisted.

I have used 3 different brands of memory to see if that was the cause. Transcend, Corsair & Kingston which all had the same result. I swapped power supplies, graphics cards, hard drives, processor, gone from a RAID 0 to IDE and back and the problem simply remains. I have done a diagnostic start-up and run the computer in safe mode for a day and still it reset. I've uninstalled every single MS update and the problem remains. I formatted my other DP45SG system and left it bare bone; without anything but windows (not even an internet connection) and after nearly 5 days it started resetting. That machine was left untouched (even by me) so NO user input or fiddling.

About 2 years ago I had this same problem with one of three IDENTICAL DG31PR systems. Eventually when the client was about to strangle me, I replaced the board out of my own pocket (with another DG31PR) and low and behold the problem went away without even having to reload the OS. This time around the problem is not simply isolated to a single board, but 3 of 3 that t I have purchased (of which one is running Vista Ultimate x64, different memory and different graphics).

Today my problem changed slightly (for the worse) when the RAID failed directly after a reset. It reported that there is no OS. I turned it off and back on and everything worked fine again (by "fine" I mean the normal lock ups and reboots ).

All I can say at this point is that Intel need to do something really drastic in order to restore faith in their brand and to not lose some very die hard Intel fans.

Hello,

         I think you've got to the point where you have changed each component of PC and i like your response which make me feel to get through this issue quickly, first of all check out your board manual for reference as it says about many issues like if you have installed 1GB in DIMM0 then also put 1GB Ram in DIMM0 B.If you don't get what you want then check for an update that resolve a issue with Intel High Definition Audio where audio devices don't give response after resume from hibernation or sleep. This update is available from Microsoft Windows Update.If you satisfy with my help then notify me or if not i will look forward for your answer.
