My PC is not nothing, all I see is just a black screen, but I hear the fan running and flashes on the keyboard and a few beeps. What? When starting to run computers, a Power-On Self Test, commonly known as POST. If problems are detected during the boot process, you can usually diagnose the error code displayed on the screen. However, if nothing appears on the screen, the computer can use sounds (eg, beep codes), you say what is wrong. Many of these errors on hardware problems indicate that a service technician to resolve. But in the beginning when you see flashing keypad twice it means that your computer motherboard works well. Otherwise, you can very well to diagnose because of something with the motherboard components. BIOS beep codes, many different, even if they seem to be the same manufacturer. This is because the motherboard manufacturer to program the codes that reflect their own adjustments. Often, you can go to the website motherboard manufacturer to find the updated code, but can be cases in which the producers did not simply present the document changes. Award Award BIOS screen generally use more error codes beep. For Award BIOS Manufactured by Phoenix Technologies, note the following points in the Phoenix Technologies AwardBIOS Error Messages page states: “The only AwardBIOS beep a video error has occurred and the BIOS can not initialize the screen display additional information. The tone is followed by one long beep two short beeps. All other beeps are probably RAM (Random Access Memory) problems. “Award BIOS are not manufactured in the Phoenix Technologies use the beeps, this information from BIOS Award Central BIOS Beep Code page: 1 long beeps Meaning, 2 short Video adapter error: Bad or improperly seated video card error beeps repeated Memory: RAM defective or improperly used an extensive menu of three short video RAM Bad video or does high frequency sound processor overheating: Check fans repeating high / low beeps CPU: False seated or faulty CPU AMI (American Megatrends) The following information from the BIOS AMI BIOS beep codes central page and what do they mean ? 1 short DRAM refresh failure 2 short Parity Error in first 64KB RAM: probably a bad RAM IC, or perhaps a test of equipment has failed three short memory failure in the first 64K of RAM Most likely a bad RAM IC 4 short System timer failure Bad Clock IC failure or bad RAM in the first bank of memory 5 short Processor: The processor has failed. 6 short Keyboard controller Gate A20 error: The keyboard controller has failed. Because of its integration into the system board, replace the rule must be the motherboard. Error 7 short Virtual mode exception: CPU has generated an exception error, bad CPU or motherboard 8GB short display read / write test failure Bad video card 9 Not running out of control ROM BIOS: BIOS is 10 short stop CMOS Read / Write error 11 short Cache error: Specifically, the L2 cache bad. 1 long, 2 short video system failure: is to trace errors in the graphics card BIOS or a horizontal axis with a long, 3 short Conventional or not the failure of the extended memory: RAM is a bad long, 8 short Display / Retrace test failed: video card is defective or missing AST BIOS The following information comes from the AST BIOS Beep Codes page BIOS Central. Beeps Meaning 1 short failure CPU register test: The CPU has failed. 2 Standard keyboard controller buffer short: The keyboard controller has failed. 3 Regulator keyboard shortcuts not reset: The keyboard controller has failed or the motherboard circuitry is faulty. 4 Error keyboard short message: keyboard controller or the keyboard 5 Bad keyboard failure: The keyboard controller IC has failed. System failure 6 short board chipset: chipset motherboard has failed. Replace the motherboard. 9 Error control short ROM BIOS: The BIOS ROM has failed. If possible, replace the BIOS on the motherboard. 10 short failure timer test system: the system clock IC has failed. 11 short ASIC failure: the motherboard circuit failed. Replace the motherboard. 12 shortstop CMOS RAM register failure: the real time clock / CMOS has failed. Replace the CMOS or motherboard. A long DMA controller 0 error: Can The DMA controller IC for channel 0. If possible, replace the IC. 1 long, 1 short DMA Controller 1 Error: Can The DMA controller IC for channel 1. If possible, replace the IC. 1 long, 2 short Video error vertical refresh: The graphics card is probably failed. Replace the video card. 1 long, 3 short Video error test memory: The memory of the video adapter has failed. Replace the video card. 1 long, 4 short Video adapter error: The graphics card has failed. Replace the video card. 1 long, 5 short 64KB memory error: An error occurred in the base 64K memory. If possible, replace the RAM IC. 1 long, 6 short interrupt vectors can be loaded: The BIOS was unable to load the interrupt vectors in memory. 1 long, 7 short video can not be initialized: This is a video problem. Replace the first graphics card. If the problem persists, replace the motherboard. 1 long, 8 short of failure memory: This is a bug in the video memory. Replace the first graphics card. If the problem persists, replace the motherboard. The following information comes Compaq BIOS Compaq BIOS Beep Codes centerfold. Meaning a short beeps No error: The system starts properly. 1 long, 1 short BIOS ROM checksum error The contents of the ROM BIOS is not the expected contents. If possible, download the BIOS from the PAQ. 2 short General error: No special features, which means that the code long, 2 short Video error Check the video card and make sure you stay upright. If possible, replace the video card. 7 beeps (1 long, 1 short, 1 long, 1 short, pause, 1 long, 1 short, 1 short) AGP video card AGP is defective. Insert the card or replace them altogether. These systems Compaq Deskpro beep. Continuous beep Memory error: Bad replace the RAM, and a short essay, 2 long Bad RAM: RAM should replace then again; RAM if the error persists.
