no keyboard detected. fatal error... system halted = your keyboard is dead, replace it. If you get the same message after a new keyboard then the PS2 connector is dead, you will have to use an USB keyboard.
A BIOS (Basic Input/Output System) is an electronic set of instructions that a computer uses to successfully start operating. The BIOS is located on a chip inside of the computer and is designed in a way that protects it from disk failure. A main function of the BIOS
is to give instructions for the power-on self test (POST). This self
test ensures that the computer has all of the necessary parts and
functionality needed to successfully start itself, such as use of
memory, a keyboard and other parts. If errors are detected during the
test, the BIOS
instructs the computer to give a code that reveals the problem. Error
codes are typically a series of beeps heard shortly after startup.
1,Check your Ram (Whether it is working or not) 2,Clean your Ram slot by a brush(Remove dust) 3,Rub your Ram golden contact by a rubber gently. 4,Try to go to bios menu and restore to default 5,Check CMOS battery and power supply(SMPS) with spare one 6,If these fixes are not working try replace motherboard
I still did not find beep code that match your problem..
Anyways here are the common beep codes for your motherboard.. it might help you too. 1. No beep - no reaction, the mother board is dead, power supply problem, processor and or ram problem. 2. 1beep - board is working fine. 3. One long beep then it shuts down - cpu problem, your processor is not working or missing. 4. 1short beep - system boots normally 5. 2short beeps - CMOS setting error. 6. 1long 1short beep - dram error 7. 1long 2 short beep - video card or monitor not connected 8. 1long 3 short beep - keyboard error. 9. 1long 9short beep - ROM error 10. Long beep - memory card is missing or not connected 11. Short beep - power supply error 12 Four beeps - there is no fan detected on Fan1 or Fan2 header. make sure to attach or reset CMOS bios to factory setting.
If what the bios error showing on the screen then that is the problem. Bios can detect faulty computer hardware like memory, vga and hard drives. It also shows an error about keyboard missing or something else. Whatever it is, it only means that you should setup the bios and devices properly in your computer to avoid this kinds of error. Find a qualified technician to do it for you. This suggestion from me to you will avoid any further complications in your computer system. But if you want to take the risk, open your computer where the motherboard lies in, find the bios jumper settings and then reset it by shorting the 1-2 pins. Look for the motherboard manual about this if your unsure what to do about it. This procedure is only the common thing to do in such kind of problem but will not guarantee that it will work for you.
First you need to know which BIOS you have and how many beeps it is producing... these beeps are the POST - Power On Self Test. They tell us if there are problems such as missing keyboard, video card not working, memory faults etc...
Then you need to go to the appropriate BIOS site and see what the number of beeps mean.
If it is a single beep - it means all is well...
As you are not getting anything more you should check to see if the Hard Drive (HD) light flashes - if so - the HD is probably operating ok and loading your system but there is either a problem with your monitor or video card... borrow another monitor and see if that helps...
But it all depends on the number of beeps you get and what kind - long and short beeps (like morse code).
try installing the software drivers for keyboard and mouse.....then see whether keyboard and mouse is working...if the problem persists.....then the problem is in motherboard.....that you have to give it to repair shop....so that you can identify the problem.....i am a software engineer.....and i have experience in these areas....thats why suggesting you this idea....try this....it will work 100%.....
The best thing to do in this situation is to build your machine outside of the case, using the minimum amount of hardware,
Remove the motherboard and using only one stick of ram, the monitor, keyboard and mouse. short the power switch connector on the motherboard with a screw driver for a fraction of a second just to power it on.
If it starts up and gives you a "no boot disk" or "no Operating System found" at least you will know it's working and you can slowly connect everything else one by one to see whats preventing it from booting.
If it doesn't start like that, remove the power cord from the power supply and remove the mother board battery for at least 15 minutes, this will clear the BIOS and set it back to factory spec, now carryout the out of case procedure already stated.
