Question about Intel DG41RQ Motherboard & Core 2 Duo E7500 Processor Bundle (INTEL DG41RQ MB & CORE 2 DUO ...)

1 Answer

Hi, I have a Intel DG41RQ mobo with short circuit problem. It starts with this problem, it beeps with no RAM but no video or beep with it; now the mobo doesn´t start, only with the 12v connector off. I have some experience repairing VRM source problems but this one seems to be to much for me; please I need some help!!!

    What? 1) It beeps with no ram. No kidding. It's SUPPOSED to. It's a BIOS Beep Code. The computers way of telling you something is wrong, and an area to look into for it. 2) It isn't going to beep with ram installed, if it's Not set up to beep once, after BIOS has done a ram memory count. 3) Motherboard starts with the 4-pin +12 Volt power cable not connected to the motherboard? No it doesn't. You might have LED lights lit, and fans spinning, but there's NO power to the Processor. Therefore it ISN'T starting. What does repairing Voltage Regulator Modules have to do with this mobo? The motherboard has a built-in voltage regulator circuit. (See any Caps out around the Processor?)http://www.hardwaresecrets.com/article/6...

    As you said, the motherboard has a built-in voltage regulator circuit, this circuit sometimes goes bad due to MOSFETs or even the ICs that drives those MOSFETs (ex. ADP3180, ADP3181, ADP3418) that makes the board doesn´t start with the 4-pin 12 Volt power cable connected, meaning this that there´s no LED lights lit or fans spinning. This mobo in particular does that, but i´m not sure if the VRM module is bad, as a matter of fact i think that the problem is on another module similar to VRM but this one gives power to RAM instead of processor. What I need is some schematic that guides me on this.

Most likely the memory is incompatible or in the wrong configuration. Check here to see the proper configuration for this motherboard.

SOURCE: D845SVR mobo - no boot

Before trying anything, try another monitor. Or try you're monitor on another system. Swap the video cable with another. (This is a must try). The reason it’s a must try is because you hear the drive run, the fan's are running & the LED's are flashing. Once you are sure both are good than reset the bios.
(You typed, D845SVR as you're board). There is no such Intel MB. I think you meant to type, D845GVSR.
Unplug the power cord from the PC, open you’re case & touch any bare metal on the inside of the case surface before touching the mother board.
Please go to page 10 in you're manual. Make sure letter "D", the 12 V power connector is secure. Remove & re-seat it. Go to page 37 for instructions if you need a little help resetting the bios jumper. Move the jumper to pins 2 & 3 for 15 seconds. Than move back to default, pins 1 & 2. The link listed below is Intel's main web site for the MB D845SVR.
http://support.intel.com/support/motherboards/desktop/D845GVSR/
If you no longer have you're manual, you can download it at the link above. By resetting the bios, you are manually changing the bios to its default settings. Plug the power cord back in.
Try booting the system. You should get display. If you do not, than you're onboard (Integrated graphics), is most likely bad. A work around would be to add a PCI video card. The only other option left that I can think of is, it is possible that the CPU thermal grease between the CPU & heat-sink has dried. This will & can cause you're CPU to heat up. It may have overheated the CPU. PC repair is trial & error. Cleaning & replacing the thermal grease may allow you're system to function.
Here are a few PCI graphics cards you could try if you wish to buy.
http://www.tigerdirect.com/applications/category/category_slc.asp?CatId=319&name=PCI-Video-Cards
Once a PCI video card has been added, the bios will use the PCI card without you needing to make a change in the bios.

Good Luck!
Mike

SOURCE: No video & 3 beep sound

Hi Sharang -

Here are the steps to take for that specific motherboard according to Intel

  • Reseat the memory.
  • Make sure that the contacts on the memory and the socket are clean.
  • Try removing one bank of memory modules at a time. Note: Some systems might need to have a memory module in Bank 0.
  • Try using RAM chips from the same manufacturer with the same part number and speed.
  • Check for a faulty memory module by trying the memory in a known good system.
  • Trying known good memory in the system.
  • Check the power supply and check for power fluctuations.
  • Swap the motherboard.
Hope that helps,

Take care,

Michael

If the cpu was bad- nothing would turn on--be sure the cable is good-- also be sure the VGA is enabled in the bios- since you cant see the video you have to reset the cmos setting--unplug the unit and remove the cmos battery-reinstall after one minute and check for video

SOURCE: My Intel Board DG41RQ beeps

the beeps are post during post the very first work is done by the ram,all the memory in the ram is first transferred to the hard disk,and remains active untill turned off.
make sure that your RAM is securely seated
test or replace all the leads that attach to your hard drive make sure the connections are secure including electrical extensions + IDE,SATA the ones that attach from your
((motherboard to hard drive))
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty or just replace them they are probably old and faulty ?
hope this helps

Hi,
Try this motherboard troubleshooting beeping code first.
No beeping means short circuit,loose parts.
One beep means everything is working good.
Two beeps means CMOS error.
One long beeps,two short beeps means video problem
Three long beeps means keyboard error.
Continuous long beeps means memory not detected.
Continuous Hi-Lo beeps means processor overheat,loose blower fan heat sink.

If no beeps need to change capacitor parts of motherboard for burn, short and open leakage.

My Intel Board DG41RQ beeps once at start up and after that it comes up with the Intel screen. After that it beeps once again and then starts to load the operating system.

Points to a mobo problem.
However, it could be a short, caused by an unseen standoff pillar making contact with the board.
I would first of all, remove the board, place it on an A.S surface and connect it to a monitor, with 1 stick of ram, No hard drive and no CD rom attached. Use a makeshift power switch to trigger the power on the Fpanel header, or carefully touch the Power pins with a screwdriver to boot it.

If that fails to work, check the board for burns, blowing capacitors and damage, especially underneath

If it does work, replace each component in turn, examine the case to see you are not placing the board on a standoff pillar that will not be taking a screw

Intel dg31pr motherboard create some problems so that display is not available


The first step is to try video with a different video card.
If this does not work remove the ram and try to power on the motherboard. If the machine gives a series of long beeps when the ram is not installed, it is a good thing. This determines if the motherboard is posting.

If the beep code occurs, try using different ram, preferably that is known to be good.

If the beep code does not occur then the motherboard itself is bad, and short of using a multimeter to determine what component on the mobo is actually bad, a replacement would be in order.

No Dispay, No Beep


Try leaving it off but with power to it (should see a small green LED on Mobo) for about 30 minutes or more.

After this time try starting it with RAM installed of course!

If this doesn't work your Motherboard is dead.
