Are you using a WinFast series motherboard? What exactly does the screen say on it? Do you hear any beep sounds from the system speaker (the one on the board, or connected through a jumper, not external speakers connected through a plug)? The number and duration of each beep (short or long). If it uses an Award/Phoenix bios, here's some beep-code troubleshooting info:

XXXXXXXXXX 1 Long, then 2 Short Beeps: Video error XXXXXXXXXX

Explanation: The BIOS is unable to access the video system in order to write any error messages to the screen.

Diagnosis: This is usually caused by a problem with the video card, or the memory on the video card. It can also be a motherboard issue.

Recommendation:

* Troubleshoot the video card.
* If the video card is not at fault, troubleshoot the motherboard.


XXXXXXXXXX 1 Long, then 3 Short Beeps: Video error XXXXXXXXXX

Explanation: The BIOS is unable to access the video system in order to write any error messages to the screen.

Diagnosis: This is usually caused by a problem with the video card, or the memory on the video card. It can also be a motherboard issue.

Recommendation:

* Troubleshoot the video card.
* If the video card is not at fault, troubleshoot the motherboard.

XXXXXXX Continuous Beeping: Memory or video problem XXXXXXXXXX

Explanation: The system is producing constant beeping in no specific pattern, or a fast "ringing" sound.

Diagnosis: This is usually caused by a problem with the system memory, or possibly the video card. The memory is more likely--the system complains long and loud if it can't find any usable memory, as there is no way to even start the boot process when this is the case. The motherboard itself could also be the problem.

Recommendation:

* Troubleshoot the system memory.
* Troubleshoot the video card.
* Troubleshoot the motherboard.


XXXXXXXX Other Beep Codes XXXXXXXXXXXXXXX

Explanation: You have encountered an Award BIOS beep code I do not have documented.

Diagnosis: Award says that any beep patterns other than "one long followed by two short" are likely problems with the system memory. However, of late they have started adding other beep codes to their systems as well.

Recommendation:

* If you have recently flashed the system BIOS on this machine and corrupted the BIOS, and the system supports the boot block feature, the beeps may be codes communicating the status of the system as it tries to recover from the failed flash procedure. This is especially likely if the floppy drive is accessed very early in the boot process.
* Contact the vendor of the system or motherboard. They often have more specific information on beep codes.
* Troubleshoot as an apparent memory problem.
* Troubleshoot as an apparent motherboard problem.

I also found that 5 short beeps repeated can mean the primary bios has faled and it is using the secondary bios on board that have backup bios.

    another possibility is that you have replaced it with an insufficient power supply. What mainboard are you using, how big of a power supply, and how much additional hardware do you have connected to it?

Hi,

I would venture that "shows winfast on monitor" indicates the type of Video Card that your PC is using. Thereafter it should go to POST showing the motherboard, BIOS, memory count and others.

Since as you posted, after Winfast nothing follows, I can only suspect that you have a motherboard problem or at least a BIOS corruption.

Please post back the brand and model of your computer or at least what motherboard.

Good luck and kind regards.

Thank you for using FixYa.

    Hi again,

    Appreciate your quick response. Winfast has been taken over by Foxconn so most information are rather hard to get.

    However, I would suggest that:
    1. reset your CMOS/BIOS using the blue jumper and temporarily moving the blue jumper to the other pair and then back to original position;
    2. check that your memory are OK and seated properly. It may need some cleaning by using a pencil eraser on the little gold pins;
    3. remove all other connections to the power supply such as your HD and CD;
    4. run the system at bare minimum and slowly, one at a time re-connect all other devices until such time everything is connected/operational or when problem re-surface. You would have then isolated your problem.

    Please update any developments (or lack thereof).

    Cheers.

    Your board looks something like this?

  • Louie  Role
    Louie Role Mar 16, 2008

    Press Del to enter into the CMOS configuration, select "Load Fail-Safe Defaults", "Y" for yes,, Select "Save and Exit Set-up.

    or

    F1 to continue as is.

    Either will work except for the date/time settings.

    Since you have reached that far, that is indicative that chances are the system will now work.

    If it detects your hard disk, then your good to go.

Hi: no power from supply opened box and checked fuse - its ok! The computer had a virus and that was fixed restarted computer and it worked ok, the next day pressed start button and nothing happened....


Test your PSU or replace it if your power supply units fan is not working your PSU is faulty

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up a computer hard drive

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your ((motherboard to your hard drive)) make sure they have a secure connection and are not faulty or just replace them there probably old and faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electrical extensions or just replace them they are probably old and faulty a computer needs its connections to have an end so any faulty leads will end up with a computer error

hope this helps

Not sure if power supply is good??


The supply fan won't run unless you turn the supply on. You can do this by shorting the PS_ON pin on the output connector to an adjacent ground pin. (This page has a nice diagram of the power supply connector.) And just because the fan starts turning, it doesn't mean the supply is good.

Measuring the output of the supply without a load can give misleading results. Especially with a digital voltmeter, outputs can look good but drop too low under load to run the computer. You can buy a power supply tester from several sources that you plug the supply into, but nothing beats an operational test in the system.

New power supplies are quite inexpensive. It might just be easier to buy one if you have any concerns that your current supply isn't working. You can also test the supply in another computer. If that one shows the same trouble as the one you pulled the supply from, you know the supply is responsible. Otherwise you know you have more troubleshooting to do in the rest of the system.

Hope this helps, and thanks for using Fixya!

How do you "warm" the computer, so that it will start properly?

Take a close look at the motherboard.
Look for those round "towers" with "silver" coloured caps.
They are capacitors.
If any caps are _not_ flat, i.e., they are bulging,
or if any caps show brown "rust" on top of the caps,
then those capacitors on the motherboard have gone bad.

Before your motherboard _completely_ dies, backup "everything" to an external disk-drive, verify that the backup has worked, and then either "trash" the motherboard, and replace it. You'll have to reinstall Windows onto the new motherboard -- find the CD/DVD set that you used to install XP.

Which two connections supply the power from the battery


Hi Ray,

In a computer, nothing connects directly to the battery, as the battery is not what powers the system. The battery controls the CMOS settings, which involves all of the things that come up before windows loads when you turn on your computer.

As for how the computer actually gets the power, there's a box in there called a power supply, which receives its power from the 3 pronged plug you put into the back of it. The Power Supply gives power to the computer through a series of different wires.

There are a bunch of 4 pin molex connectors, that go from the PSU (power supply unit) to the various drives throughout the machine. In addition, it supplies power to the motherboard itself via a 20 or 24 pin connector, that goes straight into the board. Some have an additional 4 pin one as well to supply power to the processor.

If you were looking for something else, feel free to leave a comment.

Hope this helps :)

Comp wont start up


The hard disk may have died. Check the BIOS and check the hard disk setting, if it appears OK then boot up with a DOS floppy startup boot disk, and select boot up without CD-ROM support, then type fdisk, answer Y to large disk support, select 4 to Display partition information.
If you see all your disk partition the most likely your hard disk is OK.
Most likely you operating system is damaged/corrupted and you will need to reinstall your operating system and drivers for all your devices.

Power Supply


Check all power cables plugged into M/board if these are correct
remove all hard ware
hard drives / cd player and anything else
except for video and memory and test to see if it boots. If it does, one of the removed hardware is faulty if it does not then you have M/board failure

Thats a good thought. Replace them now before they decide to self-destruct.

Like I said, they aren't "bad" computers. They generally use Intel mainboards, although I've stumbled across some "odd" ones before.

One thing you will notice is the original power supplies don't have cooling fans (some do, and some don't). I think that is what the main problem is with them - heat.

Get yourself basic Antec power supplies (they can range from $30 and up) and you shouldn't have anymore issues.

How long are the beeps? If they are shortish then it suggests that the ram on your motherboard isnt working properly. Try removing it and reseating it. Make sure all the power is turned off before doing this.

Also there is a jumper located near the bios battery for resetting the bios. Move that to the clear position then back again after a minuter or so. That will put it back to default setting.

How did the problem start? Had you been adjusting anything in the bios at all?
