No screen display at all and no short beep for post-intel D845WN board
Hi,my computer developed that problem while upgrading memory.i found a compatiable memory but cant display anything but everthing is running like HDD,CDROM,FDD,PSU,System fan and cpu fan.the led on the board is still on.What might be the problem ,give me the solution in the shortest time possible

Try the old memory back in and see if you get the bios screen showing up, if not find the clear cmos jumper either marked JBat 1, clrclk, clrcmos or similar and try again.
If neither your old memory or new no longer allows the pc to boot, i would say that the motherboard has been stressed when you have fitted the memory by forcing a flexing in the board and damaging the cmos chip, only replacing the board can resolve the issue if that is the case

If this is the first time to turn you on your computer check first the power supply of your computer if connected to their proper connector. Check your memory if clip properly in there memory slot. If you are using Video Card check it if it is properly connected to the connector. Then connect your VGA connector at the back of your computer when you have video card connect the VGA Cable of you monitor to the video card VGA output if does not have connect it with the onboard VGA output. Then press the power switch if the unit is still no visual in monitor try to search or hear a beeping sound in your computer by its on board buzzer. Find which beep you hear from your computer.
No Beep- No Power, Loose Card, or Short. One Short Beep- Normal Post,, Computer is OK. 2 Short Beep- POST error, review screen for error code Continues Beep- No power, Loose Card, or Short Repeating Short Beep- No Power Loose Card or Short One Long And Short Beep- Motherboard Issue One Long and Two Short Beep- Video (mono/CGA Display Circuitry) Issue. One long and three short beep- Video (EGA) Display Circuitry Three Long Beep- Keyboard/ Keyboard Card Error One Beep, Blank or Incorrect Display -Video Display Circuitry
Hope this help with your problem. Keep on touch in fixya
THe most common beeps that you will encounter 95% of the time in repairing PC's are:
1 beep - computer ok continous beeps / long beeps - memory error continous short beeps - bios boot block/corrupted bios 1 long beep followed by 3 short beeps - video card error
or this might help
you can check out this list
1 short - Computer ok 2 short - RAM failure 3 short - Parity RAM failure 4 short - System timer failure 5 short - Motherboard failure 6 short - Keyboard controller error 7 short - CPU failure 8 short - Video RAM failure 9 short - ROM BIOS error 10 short - CMOS read/write error 11 short - Cache RAM error 1 short, 3 long - Memory failure 1 short, 8 long - Video adapter failure
Check board/chipset makers website for more infomation.
1 long - Memory error 1 long, 2 short - Video error 1 long, 3 short - Video failure Continuous beeps - Memory or video failure
that AWARD relies on motherboard manufacturers to develop their own
beep codes - the above are only their own internal codes. You will need
to refer to your own manual for an explanation of precise codes.
Standard IBM beep codes.
No beep - Power supply or motherboard failure 1 short - System is ok 2 short - POST error (code displayed on screen) Repeating short - Motherboard failure 1 long, 1 short - Motherboard failure 1 long, 2 short - Video display adapter failure 1 long, 3 short - Video display adapter error 3 long - Keyboard error

Actually if you goto Newegg.com they have an ATI3850. This is WAAAAY better than the above mentioned card.
OR This one:
The ATI3650 is probably the highest you want to go. They do have an ATI3850, which is the fastest, and might I add, LAST AGP card. It may bottleneck your processor and that is why I linked the 3650.
it depends on the bios chip maker Here's some other beep codes:
for Award and Phoenix BIOS:
1 short beep: Normal 2 short beeps: CMOS error 1 long and 1 short beep: DRAM error 1 long and 2 short beeps: Video card error 1 long and 3 short beeps: Keyboard error 1 long and 9 short beeps: ROM error Long continuous beeps: DRAM not installed correctly Short continuous beeps: Bad power supply
1 short beep: DRAM flash error 2 short beeps: DRAM ECC check error 3 short beeps: DRAM detect error 5 short beeps: CPU error 6 short beeps: Keyboard error 8 short beeps: Video card error 9 short beeps: ROM error 1 long and 3 short beeps: Bad DRAM 1 long and 8 short beeps: Video card error
Invoking Beep Codes
If the computer is actually functioning and the computer beeps continuously, then there is a problem with a voltage on the power supply being incorrect or the CPU overheating. IMMEDIATELY go into the BIOS and check CPU temperature, fan speed and voltages
Annoying isn't it? You have built your computer you switch it on and then nothing happens except a few beeps from the PC speaker. Frustration sets in as you try to figure out what is wrong with it. If you didn't already know the computer has already told you the problem. It can't speak of course but it can direct you to the problem. Its all in the beeps. The BIOS can recognise when the problem occurs and sends a signal out to send a certain amount of beeps through the speaker. These beeps then tell you the location of the problem.
Unfortunately not all the BIOS' use the same codes as each other. Two of the main BIOS manufactures AMI and Award (now Phoenix) have different codes for there errors.
# of Beeps Error Description 1 Refresh Failure The memory refresh Circuitry is faulty 2 Parity Error Parity error in the Base (1st 64K) of memory 3 64K Base Memory Error Memory error in the base memory (1st 64K) 4 Timer Not Operational Timer 1 is not functioning (also caused by error in base memory) 5 Processor Error CPU error 6 8042 Gate A20 Failure Unable to switch to protected mode 7 Processor Exception Interrupt error The CPU on the CPU card generated an interrupt error 8 Display Memory Read/Write Error Video adapter is missing, incorrectly seated or has faulty memory 9 ROM checksum error The ROM checksum does not match that of the BIOS 10 Coms Shutdown Register Read/Write The shutdown register for coms RAM has failed 11 Cache Memory Bad The cache memory test has failed. Cache memory will be disabled. *** DO NOT enable it ***
With the first 3 beep codes, its well worth re-seating the memory just to make sure that it's in correctly. 8 Beeps is probably the most common in my experience. Can be caused by a badly seated Graphics card. If you have re-seated it then check with another Graphics card in the board.
Always check for loose components before sending the board back as this is the main cause of errors on the POST.
Award states that they now only use one beep from there BIOS. This beep is one long beep and then two short beeps. This indicates a graphics card problem. Any other beeps should be treated as a RAM problem first and then the board sent in to be inspected.
The reason that the Award BIOS only uses the beep code for display problems is that it tries to display the error on-screen if at all possible. If the BIOS cannot initiate the display adapter then this causes the BIOS to make the beep code for a display error, which must be corrected before any other errors can be determined. Memory Test fails and hard disk failures etc will all be displayed on screen
The IBM BIOS works with Short and Long beeps as well as the Award BIOS. However the IBM one does still have codes to work from.
Beep Code Error 1 Short Beep Normal POST, System booted OK 2 Short Beeps POST Error - Code on Display No Beep Power supply or Motherboard error Continuous Beep Power supply or Motherboard error Repeating short beeps Power supply or Motherboard error 1 short, 1 long beep System board error 1 long, 2 short beeps Display adapter error (MDA/CGA) 1 long, 3 short beeps Display adapter error (EGA/VGA) 3 long beeps 3270 keyboard card Phoenix BIOS The Phoenix BIOS works on a slightly more complicated manor than the others. It does display an error code for you and produce a series of beeps. This BIOS produces its beeps according to the hexadecimal code the error produces. The Phoenix BIOS has many different codes for its possible errors and so many different beep codes. Rather than list the entire section here, I have provided a link to the official PDF file containing the codes and how they are derived.
Phoenix BIOS Post Codes
System board errors should be looked at by a specialist, Again always try to re-seat components to ensure they are in correctly. If necessary take all components out except for the RAM CPU and graphics card, then try the system. Re-seating components is the number one fix for getting past the POST screen. One badly seated components can cause the entire system not to function. so pick out your bios and follow the steps above to diagnose .hope this helps
When upgrading or increasing memory. The DIMM's should be the same. The Intel D845WN board requires the memory to run at 3.3volt. If the memory you are adding is within the Intel spec's, than switch the two Dimm's. Insert only the new DIMM & check if the system hangs. If it does than it is possible the new memory it either not compatable or is defective. For more information about the D845WN board download the manual for you're Intel board. http://support.intel.com/support/motherboards/desktop/d845wn/sb/cs-008937.htm
What do you mean? You want to see if your memo reach 3Gigs because you put 3gigs on it? If thats the case, maybe the video share by your motherboard is almost 1gig? [do you have an outboard video card?] if none, thats what Im talking about[maybe the video share by your motherboard is almost 1gig]
