    Is the beeping continuous? Have you made any recent changes to the system? (i.e. adding additional memory?)

Sir usually in beeping its either you have a damage peripherals so it will not work and have you recently place new cards or hardware on your board? if you did or not please remove all hard ware and carefully place them back again and make sure that they will contact on their corresponding pins, then try plug it again, and make sure that all of your hard ware are in good condition and no damage even one. please try this solution please send us your feed back thank you and fixya..

I have just installed a 478 socket MSI MS-6526 ver 3 motherboard to my computer and all it dose is bleeps when i turn it on any help would be apricated


check for the error beep if you hear continues beep it means issue with the memory. check the RAM if it is properly inserted to the slots and if it is compatible to the motherboard. if you hear 2 or 3 beeps it means issue with the video. your video card maybe not compatible or not properly inserted to the slot. your motherboard has a built in VGA/Video card try using that first. try connecting the main components memory/RAM, power supply, KB and mouse, VGA card(optional you have a built-in) then check if there is a display or if it booted. then one by one add your other components you want to add. just to trace the problem.

Pc boots but no display. tried a new video card, still wont work. ram or motherboard?


Hi.
To start the troubleshooting,
Do one thing.
Clear the cmos.
To clear the cmos, remove the battery and the cmos jumper. You will see JCC on the mb and it is attached to pin 1&2
You can Short it to pin 2&3 or remove it completely.
Don't forget to remove the power-cord from the power supply while clearing the cmos. together with the cmos bat & jumper.
After that try a different ram and a different vga card.
At times dust get accumulated in the slot that prevent firm contact with the vga slot or the memory bank.
Use a clean paint-brush and blow away the dust on the card, the mem and also the slot in the mb.
Fix it firmly.
try this
If you need further assitance revert back
Good luck

Can i use ddr2 ram in my pc inplace od ddr1 i cn purchase pc 07?


Hey there, Check for the slots given on your motherboard, whether all the slots are same; However a motherboard can support only one type of module either DDR1 or DDR2. your motherboard has only DDR1 slots. You cannot upgrade DDR1 to DDR2 cause the Memory Module or notches are different than eachother. Gimme Acknowladgement by rating me. Thanx - Romy Decostza

At POST I get 2 short beeps


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


AMI BIOS:

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

**********************************************
BIOS Beep Codes

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.

AMI BIOS

# 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 BIOS

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

IBM BIOS

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

Few questions about RAM memory?


Solution:



i)  LOW DENSITY modules have 100% compatiility with ALL systems and ALL chipsets.
    HIGH DENSITY modules only have 10% compatibility

    here compatablity means LOW DENSITY RAM are accepted by all system(100%)  or any make           system.. HIGH DENSITY RAM are accepted by 10% by only some system or computers...


ii) in order to check system performance or amount of Computer RAM usage press the ctrl+alt+del
   simultaneously a new window(window task manager) will appear showing:

    CPU usage: showing the amount of CPU or processor utilized at that particular time.
    PF usage: showing the amount of RAM memory utilized at that particular time.
    Physical Memory: showing Total RAM Memory, Available Ram memory....

iii) baiscally they are two types of RAM they are:

    DDR1:which is older one supported by older system  or older mother boards which is costlier
    DDR2: which is latest one supported by all new system or new mother boards which is less                         costlier

    DDR: double data rated ram......which will send data at a double rate compared to SD RAM

iii) here color doesnt matter, these slots either support DDR1 or DDR2 but not both at a time
    
    DDR1 has 184 pins or gold plated pinssss... on the edge of the RAM
    DDR2 has 240 pins 

    so difference doesnot allow DDR2 to placed in DDR1 motherboards or vice versa...

iv) it does have anything to do with no of chips on the RAM but they only differ whether it is DDR1 OR DDR 2(DDR2 are much faster than DDR1)

NOTE: whatever may the the RAM, each RAM has FSB(called Frequency...) which determines the frequency of rate at which data is tranferred from RAM to processor(CPU)  usually in MHZ such as FSB 300, 400, 200 , 333...................

more the FSB the faster data is transferred to the processor(CPU)

dont worry even RAM with less FSB's work well with the processor....having 1 GB RAM or 2 GB RAM is engouh, it only matters with the speed of CPU ... but not RAM......

Ram problem


OK 3 beeps indicates memory failure - specifically the first 64K but that is not surprising.

Have you tried to put the 256M RAM in slot 1 and the 512M in slot 2?

If this does not work try the following.

There is NO "load optimised" option in this BIOS according to the MANUAL

refer pages 42 - 45 of the manual and remove the BIOS battery and check it is OK. the voltage should be 3VDC. IF not replace it.

Removing the BIOS battery for a few minutes will clear the BIOS and reset to default settings.

You will need to go into BIOS and set date/time.

Please post results so I may assist further if required
