Hi clark_styx,

Yours is not an uncommon problem. Let's get to it:
-First, did you change any thing i.e bios upgrade? If so, we'll get you to available BIOS codes.
-Next, does your cpu seem to be slowing down? If, so, it could be a heating/cooling issue i.e. cooling fan failure. Take off the case and clean out the dust bunnies.
-BIOS failure at power on? Usually means your BIOS is corrupted. BIOS upgrade reccommended.
Your cpu runs whats called a POST- (power on self test) a diagnostic utility, if your BIOS is failed or failing you will either see BIOS failure codes or hear a series of beep codes. Check these areas and if your still having BIOS issues hit me back, we'll get you going of die trying, lol.

Thanks for using FixYa.com

Hi,

To your query, "...signs of a BIOS failure...", a few I have come across on desktops:

  • "Boot Block" message;
  • twee-dee beep (often with Asus);
  • continuous beep (not sequenced);
  • will not retain day/date/time even with new battery;
  • parts of CMOS/BIOS setup/config defaulting;
  • no boot.
Hope that this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

How to manage BIOHD-8 Error Code


Hi

If your drive is showing a SMART error I would consider replacing the drive as its showing the 1st signs of failing and if you don't have backups of any important data on there I would back it up now as when it failes you wont have any way of recovering your data

How to isolate issues between hardware and software


<p>It has been one of the dilemma of computer users is to identify what is really causing the failure in their computer. Often they think that they bought a defective product since they are getting these kind of errors in the computer. Having an error on your machine does not mean that the machine is defective or needs parts replacement. for all we know it might just need some simple troubleshooting steps to fix the issue. Here is a tip where you would be able to know if you need to bring your computer to a service shop for parts replacement or you can try to fix it at home by doing some troubleshooting steps that would help fix software failure in the computer system.<br /> <br /> On a Windows based operating system, you should always know when the issue happens. It will help much to observe your computer on how it boots up and what it does before you get to the desktop screen. Take a note on where and when exactly the error occurs.<br /> <br /><b> Power Failure:</b><br /> <br /> This is an issue where there are no lights on the power button of your computer, whether it is a portable system or a desktop computer. Obviously this is a hardware failure. surprisingly, discharging the flea power of your computer sometimes resolves these kinds of issues. Otherwise, you will definitely need to have a local technician look at your system for parts replacement.<br /> <br /><b> Note:</b> flea power is the charged power of our computer system. A computer system is made up of electronic components such as capacitors which hold electronic charges. To be able to discharge it, you should disconnect all power source from your computer and hold the power button for at least 5 seconds.<br /> <br /> <br /><b> POST Failure:</b><br /> <br /> POST is an abbreviation for Power On Self Test. as the name implies, it is the test that a system goes through to test the basic hardware components needed for a computer to boot. The components that it tests are as follows: Processor, BIOS (Motherboard), Memory, keyboard and video card. If there is a POST failure, the system would give you a black screen with lights on the front panel. Sometimes it will give you beeping sounds which would normally mean that you have a memory failure on your system. If you encounter such issue, you will need hardware technical support to guide you isolate further on what could be causing the failure.<br /> <br /><b> Boot Failure:</b><br /> <br /> Boot failure is when the computer is able to complete post. You will be able to know this if you hear a single beep on your computer. Isolating a boot failure from a post failure simply requires you to boot to the System Setup/configuration Screen (BIOS). If you are able to get to the BIOS, that means all the POST hardware component are good to go. However, booting to the BIOS differs per system. You just need to do trial and error on the following keys to tap as you turn your computer on.<br /> <br /> Del<br /> F1<br /> F2<br /> F10<br /> F9<br /> ESC<br /> <br /> To isolate an issue whether it is a software or a hardware issue, you just need to boot from the BIOS. If you are able to boot from the BIOS, chances are it is not a hardware failure and needs servicing.<br /> <br /> <p><img src="vincent_von_0.jpg" /><br /> <p><br /> If booting to the BIOS works, to further isolate the issue whether it is the advanced software, you need to boot to Safe mode. Safe mode is a troubleshooting state where only the basic applications and drivers are active. If you are having errors or boot failure, try to boot to Safe Mode. If you do not encounter the failure in Safe Mode, that means that there are advanced software being loaded in your operating system that fails. It is just a matter of knowing what that software is.<br /> <br /><b> Booting to Safe Mode:</b><br /> <br /> 1. turn computer on and tap on F8 before Windows starts.<br /> 2. You will be getting the Advanced Boot options. Use the arrow keys to get to the option for Safe Mode.<br /> <br /> <p><img src="vincent_von_0.png" /><br /> <p><br /> <p><br /><b> Safe Mode Definitions:</b><br /> <br /> Safe Mode: Just basic software are being loaded. Network drivers are not included which means no internet connection<br /> <br /> Safe Mode with Networking: Basic software and Network drivers are being loaded.<br /> <br /> note: for Vista or Windows 7, it includes wireless network drivers. This means that you can still connect to the internet with a wireless connection. In Windows XP, the wireless driver is not included even if you boot to Safe Mode with Networking<br /> <br /> Safe Mode with Command prompt: this is a troubleshooting state where you will be able to utilize DOS based commands.

Beep Code Manual


(I'm Computer Technician, I use these codes to trouble shoot hardware issues at my job. Enjoy.)

BIOS Beep Codes

When a computer is first turned on, or rebooted, it's BIOS performs a power-on self test (POST) to test the system's hardware, checking to make sure that all of the system's hardware components are working properly. Under normal circumstances, the POST will display an error message; however, if the BIOS detects an error before it can access the video card, it will produce a series of beeps, and the pattern of the beeps indicates what kind of problem the BIOS has detected. Because there are many brands of BIOS, there are no standard beep codes for every BIOS.

The two most-used brands are AMI (American Megatrends International) and Phoenix.

Below are listed the beep codes for AMI systems, and here are the beep codes for Phoenix systems.

AMI Beep Codes

Beep Code Meaning
1. beep DRAM refresh failure. There is a problem in the system memory or the motherboard.
2. beeps Memory parity error. The parity circuit is not working properly.
3. beeps Base 64K RAM failure. There is a problem with the first 64K of system memory.
4. beeps system timer not operational. There is problem with the timer(s) that control functions on the motherboard.
5. beeps Processor failure. The system CPU has failed.
6. beeps Gate A20/keyboard controller failure. The keyboard IC controller has failed, preventing gate A20 from switching the processor to protect mode.
7. beeps Virtual mode exception error.
8. beeps Video memory error. The BIOS cannot write to the frame buffer memory on the video card.
9. beeps ROM checksum error. The BIOS ROM chip on the motherboard is likely faulty.
10. beeps CMOS checksum error. Something on the motherboard is causing an error when trying to interact with the CMOS.
11. beeps Bad cache memory. An error in the level 2 cache memory.

1 long beep, 2 short Failure in the video system.
1 long beep, 3 short A failure in the video system.
1 long beep, 8 short display test failure.
Continuous beeping A problem with the memory or video.
BIOS Beep Codes

Phoenix Beep Codes

Phoenix uses sequences of beeps to indicate problems. The "-" between each number below indicates a pause between each beep sequence.
For example, 1-2-3 indicates one beep, followed by a pause and three beeps. Phoenix version before 4.x use 3-beep codes, while Phoenix versions starting with 4.x use 4-beep codes.

The PC does not start.Only it beeps and a red light blinks,also fen is not working.


here are some of the basic codes, depending on which BIOS you have...

Also you do not indicate which fan? I would guess you mean the main Power Supply (PS)? In which case it could just be you need to replace the PS.

Here is a link to some other codes as well...
http://www.computerhope.com/beep.htm

AMI BIOS ERROR BEEP CODES
  • 1 Beep - Memory Refresh Failure (check memory)
  • 2 Beeps - Memory Parity Error in first 64KB block (check memory)
  • 3 Beeps - Memory Read/Write Error in first 64KB block (check memory)
  • 4 Beeps - Motherboard timer not functioning (possible motherboard replacement)
  • 5 Beeps - Processor Error (may need replacement Processor)
  • 6 Beeps - Gate A20/keyboard controller failure (possible motherboard replacement)
  • 7 Beeps - Processor Exception Interrupt Error (may need replacement Processor)
  • 8 Beeps - Display Memory Read/Write Failure (reseat or replace video card)
  • 9 Beeps - ROM checksum Error (replace BIOS chip or motherboard)
  • 10 Beeps - CMOS shutdown Read/Write error (possible motherboard replacement)
  • 11 Beeps - Bad Cache Memory - test failed (replace cache memory)

Phoenix BIOS ERROR BEEP CODES
Phoenix BIOS beep codes are a series of beeps separated by a pause, for example:
beep --- beep beep --- beep --- beep beep would be 1-2-1-2
  • 1-1-4-1 - Cache Error (level 2)
  • 1-2-2-3 - BIOS ROM Checksum
  • 1-3-1-1 - DRAM Refresh Test
  • 1-3-1-3 - Keyboard controller test
  • 1-3-4-1 - RAM Failure on address line xxxx (check memory)
  • 1-3-4-3 - RAM Failure on data bits xxxx of low byte of memory bus
  • 1-4-1-1 - RAM Failure on data bits xxxx of high byte of memory bus
  • 2-1-2-3 - ROM copyright notice
  • 2-2-3-1 - Test for unexpected interrupts
I hope this helps.

Continuous beeping sound


Do you get video? If so then it could be a stuck key on the keyboard.

Do you get no video? If so then reseat the RAM.
