Question about Computers & Internet

No Beep, No LED Read-out just - -

This began over the Thanksgiving holidays, 07. My computer would not boot to the BIOS. After stripping everything down to only the CPU and mobo, I assumed it was the mobo. I sent it back and it was found faulty. After I got a replacement board, it did the same thing. I sent back the CPU and it was found faulty as well. After I got a replacement CPU, it did the same thing. I went and bought a new PSU and it did the same thing.

I now have another RMA with the mobo supplier, but they swear they tested the replacement board before it went out. So, before I send this board back, I thought I'd get some advice here. Below are my specs.

Mobo: Nvidia 590 AM2, SLI, MCP, ATX, AMD
CPU: AMD Athlon 64 X2 6000+ Windsor 3.0 Ghz, Socket AM2
PSU: Rosewill RP 550V2-S-SL, SLI ready
MEM: Corsair XMS2, DDR2 800, PC 6400, 1GB x4

    No. The computer will not work at all and can not even get to the BIOS. And, I've reset the CMOS and removed/reinserted the battery.

    Yeah, this problem has perplexed every computer repair shop within a 50 mile radius. They also can't test the board being it's a 4+4 pin ATX. However, I've heard that mobo's are sometimes sent around on a continuous cycle (Conspiracy Theory). But the supplier insisted that it was tested before it went out. I've finally talked to a traveling computer repairman and I hope to hook up with him in the next couple of days to see if he can test the mobo and CPU. I really want to get this info before I send the mobo back and look like an idiot :). Thanks for the reply!

  • Pythium Feb 25, 2008

    When on the phone with the mobo supplier, they had me take it out of the case for the very same reason. Since then, i've left it out of the case to continue to run tests. The only thing I haven't tried is different/ new RAM. However, for 4 sticks to go bad at once would be extremely rare and I would think if the RAM was bad I'd get some kinda of POST error code or beep. I get neither.

    Tks again.

  • Pythium Feb 25, 2008

    Haven't tried the VOM yet, but I ruled out the PSU when I tried a new one. Yes, all fans and lights on the mobo coming on but - - on the LED and no beeps. I may try a VOM (assuming you're meaning Voltage Meter) tonight. I guess either the mobo manual or PSU manual would list the correct voltages i should receive.

  • Pythium Feb 25, 2008

    Oh..and yes. I've tried all configurations possible with the RAM. With all the reading i've done, on this board and others, it's got to be the mobo, if not the CPU. The main reason I'm ruling the CPU out is of these (3) things.

    1. The new CPU came in a retail package. It looks and smells new.

    2. The mobo came packaged as an OEM part. Yes it may be new, but it didn't make me feel all warm a fuzzy like the CPU did.
    3. They are no longer making the 590 board. Suspicions arise with that as well.

  • Pythium Mar 12, 2008

    Update...The 2nd mobo was bad too. The customer support rep. said that the 2nd board was good when it left their shop; true and tested, and that it must be either something I'm doing or one of my hardware components is destroying the board. I had my PSU tested and it was ok, so what the heck are they saying. The only other conclusions I could think of were:

    1. The CPU was bad too; therefore it did something to the board.
    2. The RAM is bad, therefore it damaged the board. (mentioned by their customer support)
    3. Static electricity?

    Granted, these are far fetched conclusions, but I don't want to damage the next board they send me if it is.

Sounds like you have pretty much covered about everything. Are you saying that the system works OK, except when you try to get to BIOS, or is it not working at all?

If you are just having trouble getting into BIOS, there is the possibility that something is wrong with the F key that you use to access BIOS. Might try a different keyboard if this is the case.

I know that this is kind of a stretch, but haven't been able to think of anything else, yet.

    Strange one, huh?
    Did have one other thought. Is there any chance that the MoBoard might be shorting out on a screw or on the case? Have had this happen to me due to improper reassembly and/or missing insulation on bottom of the board.
    Another possibility is a bent pin on CPU, but assume you have checked for that.
    With only the PSU, CPU & board installed, it should do something at least.

  • Ron Roske Feb 25, 2008

    Agreed that one wouldn't think that 4 sticks would go bad at the same time. Have you tried bringing it up with only 1 stick of memory? Then try to bring it up with a different stick? Is it safe to presume that the fan(s) come on when it is powered up? Have you been able to use a VOM to check the voltages from the PSU to the board to verify that they are there and correct?
    Any lights or LEDs coming on?

    I know that these suggestions are pretty basic, but we're starting to run short out of ideas.

  • Ron Roske Feb 25, 2008

    Sorry 'bout that! Yes, VOM means volt ohm meter. And, yes, the manuals for either (or both) should give you the numbers.

No boot - short beep, long beep (it is not a memory problem)

When your computer boots up, the Basic Input-Output System (BIOS) performs an all-systems Power On Self-Test (POST).
The POST tests your computer's most important components, including the motherboard itself, the system's memory and the video card.
If the computer deviates from its standard beep, it may indicate a very serious problem with your computer, or it may simply indicate that you need to replace a system fan or a memory stick. BIOS beep codes vary according to manufacturer.

Start your computer.
Pay attention to the number of beeps and the length of the beeps.
There are short and long beeps.
Write down your observations.
Write down the BIOS type if this information is on your screen.
Consult your computer documentation if you don't know what type of motherboard you have.
Visit your computer manufacturer's support website for your computer model if you purchased a pre-built machine.

Look up your BIOS manufacturer (AMI, Award and Phoenix, for example) at a BIOS beep code website such as 5StarSupport, PC Hell or PC Guide (see Below).
Match the your computer's beep code with the beep code listing for your BIOS manufacturer.

My emachines desktop ET1161-07 is randomly playing a high-low beep

A virus check might not get all malware. Download Malwarebytes free and do a scan with that. Check the add-ons installed in you browsers and get rid of superfluous or strange ones. Use msconfig to check which programs are loaded at start up. Uncheck unnecessary or suspicious ones. Good luck.

Inspiron 531s will not boot up, keeps beeping, saying it is in power save mode. How do I fix the problem

System Beep Codes The Inspiron™ 531 / 531s system can emit a series of beeps during start-up if the display cannot show errors or problems. These series of beeps, called beep codes, identify various problems. One possible beep code consists of repetitive three short beeps. This beep code indicates the computer encountered a possible system board failure.
The series of beeps has a 3-second delay before it repeats. The series and delays continually loop until you press the power button.
Code Description Suggested Remedy 1 BIOS ROM checksum in progress or failure System board failure; covers BIOS corruption or ROM error 2 No memory modules detected
  1. If you have two or more memory modules installed, remove the modules, reinstall one module, and then restart the computer. If the computer starts normally, reinstall an additional module. Continue until you have identified a faulty module or reinstalled all modules without error.
  2. If available, install a good memory module of the same type into the computer.
  3. If the problem persists, contact Dell.
3 Chipset error (North and Southbridge chipset, DMA/IMR/Timer Error for Intel® platform); chipset error System board failure. Power LED is blinking amber. Time-Of-Day Clock test failure Gate A20 failure Super I/O chip failure Keyboard controller test failure 4 RAM read/write failure
  1. Ensure no special memory module/memory connector placement requirements exist.
  2. Verify the memory modules you are installing are compatible with the computer.
  3. If the problem persists, contact Dell.
5 Real time clock failure. Possible battery failure or system board failure.
  1. Replace the battery.
  2. If the problem persists, contact Dell.
6 Video BIOS test failure Video card failure 7 CPU cache test failure Processor failure
