Re: 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.

I am not sure if you have tried this, but take one stick of ram put it in the first slot. Try to boot if it beeps or not, power down and move to the next slot with the same chip (we are assuming this is a good ram chip). Repeat for every slot on the computer. If you have 1 or 2 slots that beep and the rest do not; bad slot on the mother board. If all slots beep, try a different chip (bad ram??). If no slots beep, repeat steps with each individual ram chip (you could have just one or two bad and causing all the issues).
your bis/firmware will be corupted.download latest firmware in bootable cd format and update bios.even if mb doesnot give display it can boot and flash the bios.(follow website for details on how to make cd-iso)
it could be dead mobo, it's actually the most probable cause of your problem, but there is this thing i've encountered with HP several times already. i know it's a long shot, but i'd like you to try and boot the laptop up after you've removed the DVD-drive. if this works, it's the DVD-drive that's broken, if not, it'll be the mobo...
Is there any beep from the motherboard?
First thing that you need to check is the RAM. unplug the power cord and remove the RAM. Now, plug in the power cord and try switching the Comp and see if there is a any sound from Mobo. It should idealy warn you that there is no RAM with continous BEEP. If that happens, the Mobo is fine.... Grab a new RAM and try it out. The system should boot now. (If there was "No RAM warning beeps" when you switched on the system without RAM).
There are many issues that may put down the Mobo but in most cases its the RAM that stops functioning...
Try this and see if it helps. Please post your result here so that we can see if you need further assistance.
Try without any RAM and see if there is a beep...if there is then mobo is ok. If no beeps still. Check the CPU. Also check the PSU if its giving adequate power to all the added cards. If possible try with another PSU.
Try clearing CMOS as well. If all these doesn't do any good to the mobo, I think its time to RMA the mobo.
Have a great day!
While booting BOIS goes for POST check for detecting the all the hardware .
Disconnect all the connection to DVD, HDD, FDD from MOBO.
Rmove all RAM and start the ssytem from testing RAM Serviceability. If you listened a long intermittent beep place a single pices of RAM in MOBO ( repeat test with other RAM also).
Other wise your video card is unserviceable, if you have any addon plugins like NVIDA graphics card you can check
how to fixed your motherboard no display and no beep, 1st you must clean your memory using eraser and brush for painting if not display again try to clean your video card if have a video card using again the eraser and painting brush if not display again try to pull out the bass in the cdrom and floppy disk. if not display you must replace the memory and video card., if not display try to change your motherboard. The beep put speaker in the motherboard.. gudluck guys
