I have exact issue, i found MOSFET bad it is near processor and has markig (Q36) It is N-cnannel mosfet. I order new and waiting to recive it.

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

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.

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.

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!

Hi Sharang -
Here are the steps to take for that specific motherboard according to Intel
Hope that helps,
Take care,
Michael
SOURCE: Building desktop: no beeps, no video
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

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.
