    same problem. please help!
    mobo: asus p4ge-mx

    i tried running only RAM, CPU, PSU, and video card, nothing... still no display
    I tried replacing the PSU, same issue... all 3 times

    it started with a psu that plugged in and just randomly turned on by itself without using the power button. CMOS wasn't even plugged. I tried replacing battery aswell... and still turns on after i switch on the PSU
    the mobo LED light blinks which is pretty abnormal... the PSU that started this killed another computer. so whats happening?

    If I understand you correctly, whenever you plug in power, the power supply starts up, but then you don't get anything like it's booting up. Is this something new it's started? There is usually a on/off switch on the power supply beside/above/below the power cord connector. If it's off, it shouldn't power up. Have you put it together yourself or recently upgraded the MB or CPU? I haven't tried this, but maybe the power switch connection on the MB is opposite what it should be or even on the wrong jumpers.

250 w is a rather low wattage power supply. That's one thing I would change if you have spare parts available. Here is what I would try:
Remove the memory and blow the dust out of the system. If you have more than one memory chip, put only one in and attempt to reboot. If that does not work, swap memory chips and try again.

Good luck.

Why is power up for intel DQ965CO start up unreliable?


"No bios screen" If you mean that the screen is totally dead with no response at all, but when you power-up you DO hear the normal system beep, then first check your video cable to make sure connections are tight. Take the monitor and plug it into a different computer to make sure that the monitor has failed or not. If the monitor tests good, your case cooling fans and the CPU heatsink fan do spin up, if you do not get the usual system beep when booting, then you have a low-level failure of a component. This could be caused by only one of three things: your CPU (processor) has failed, the motherboard has failed, or possibly there is a problem with the power supply. I hang out at www.suggest-a-fix.com which is a free computer help forum. Post in the Hardware section and I will be along. This forum is not set up for complicated problems that require back-and-forth, in-depth communication.

I always have failure to boot and have beep sounds. Already installed asus update v6.10.02, still shows overclocking failed on start up and requests to configure BIOS. My system includes: inno3D-FX5500...


1-Does your computer show any sign of response after power button press?
2-Is your power cable properly connected and have main power switched on both your power supply unit and the wall plug?
3-Is the 20/24-pin ATX power connector has been connected between your motherboard and power supply?
4-Can The standby power LED (Green blue) light up continuously after the mains power is connected? (Note: Both flashing and off are no good here)

Fix 1

(1) Isolate The power going into your system ( i.e. connect your system to the wall plug directly, without sharing the power with any other devices via power extension cable.)
(2) Check if the power supply and power cable functions correctly, and have the input of your power supply set to the correct position (either 100/110V or 220/240V, depending on your country)
(3) Please try replacing your power supply.

Fix 2

1. No POST

1.1 Please clear CMOS to have a try (refer to motherboard manual for details)

1.2 If the problem still persists, please contact your retailer for a check


2. There is error message during POST: BIOS ROM checksum error. Detecting floppy drive A media... Insert system disk and press enter

2.1 If the support CD supplied with motherboard is available

2.1.1 Please restart system and put support CD into optical drive, then the system will recover BIOS automatically using CrashFree utility

2.2 If the support CD supplied with motherboard is not available

2.2.1 Prepare a formated floppy disk, then unzip the BIOS file downloaded from ASUS website into the floppy disk.

2.2.2 Please restart system and insert the floppy disk into floppy drive, then the system will recover BIOS automatically using CrashFree utility
2.3 If it is not helpful after the troubleshooting as the steps 2.1 or 2.2, please clear CMOS( referring to the manual introduction)

Fix 3

Please try the latest BIOS. I recommend you to use AFUDOS to update BIOS. You need to unzip it to get the ROM file.

You should use the command as follows:

AFUDOS /i[biosname]

or, afudos /i A:\BIOSNAME.rom(if the BIOS file is in the floppy disk)

You can store your BIOS into a floppy disk or a hard disk with FAT format. Then, you will be able to use AFUDOS to access the BIOS ROM file.

If it is not convenient for you to use DOS and AFUDOS, you can try to use EZ Flash. You can save the BIOS file into a flash disk then boot the system and enter BIOS, then you can update your BIOS by EZ Flash which is in the BIOS Tools page. Please load the default settings in BIOS after you have succeeded updating BIOS.

Video adaptor giving beep code on post Asus M/B M2NPV-VM 1 long then 2 short beeps also has a usb over current issue at post but has no usb pluged in. please help me decifer this. thanks in advance troy


This is a fix that worked for me, however I cannot tell you why or even feel that I had done anything which would constitue this as a fix. I leave my PC on 24-7 and came in one morning and it was locked up. Couldn't get a video screen, not even reset worked so I threw the power switch on the back of the power supply. Turned the switch back on and pushed the power up button. The MoBo started 1 long and 2 short beeps, repeating. I pushed the reset button and same thing. I again turned the power supply off, then on again and same thing with the beeps. So this time I turned the power supply off then also un-plugged the power cord to the power supply. I left it that way for maybe 10 minutes, while I did a few other things. I plugged the power cord back in, turned the power supply back on and hit the power up button. My PC booted up...no problem. ???

Point is - this issue as reported by others may just be a hardware or bios fluke and needs a power reset or maybe even clearing the bios and restarting. Reseating the memory sticks, use just one memory stick and rotate the memory sticks to sort out the possible bad one and reseating the processor may also help.

After power on Fans are running but no Videosignal, no bios startup.


Could be 3 things Memory or CPU or Powersupply. are you getting any beeps if so how many, how long. try taking all the memory out and powering up see if it beeps if so try to put one stick of memory in at a time and see if it will boot. if you get no beeps with memory out check powersupply some PS's have a red switch on back for current input. switch back and fourth about 20 times uning a pen and set it to the right current for you location. put ram back in see if it will boot if not its trial and error of the PS and the CPU replacement and it still could be the RAM giving false readings. yea i know sounds like a ball of fun.

Here's the compaq beep codes

http://h10025.www1.hp.com/ewfrf/wc/document?docname=bph07107&cc=us&lc=en&dlc=en

As you can see your codes are not listed so I would presume you have the Award BIOS and your problem comes under "Other beep conditions" = memory errors.

Motherboard


How about your screen; is it good?

Your monitor cable, is it damaged?

Does the computer beep, to tell of booting progress?

Is the new MoBo really new? What about the video card?

Try different RAM. Bad RAM will not let a computer boot.
Try booting the MoBo out of the case: lay it out on wooden surface and plug in power supply and monitor, then turn on. Listen for beeps, HDD cranks. Also watch the screen.

Come back after doing these checks so we can isolate the problem.

Computer freezes during startup


Hi, This is typical when the motherboard (CMOS/BIOS) is having a difficult time auto detecting the devices installed including drives, videocard, sound card, network, etc. Initially set your CMOS/BIOS to default/fail-safe settings, save & exit. Perhaps you can try running with the barest of add-on devices as you have posted initially, but do it one step further, remove everything including that one last HD (with the correct jumper settings). If you have onboard video use that one rather than an AGP or PCI-E add-on. Run the unit with just a single memory. No cables other than power and front panel. Thereafter connect your devices one by one and try every time a new one is added. This include removing any USB devices/cables plugged in. More often it is an add-on that causes freezing at this point as you have described. You may also venture in trying to flash your BIOS (however pls be forewarned of possible difficulty/failure when doing so). Hope this be of some help/idea. post back how things turned up or should you need further information. Good luck and kind regards.
