Hi. I know that this is an old question, but let me share my experience with this motherboard in case that it helps someone with the same problem. I had exactly the same problem, the fans worked and the harddrive light was on, but the motherboard did not start. The motherboard did not even beep; even when I took the memory modules out it did not beep at startup. The fans just started and then it sat there doing nothing! I wasted hours on this and was convinced that the motherboard was faulty... but then I thought of trying the following and it worked:

On the motherboard JCMOS1 has 3 pins; pins 1 and 2 are closed in normal operation. Closing pins 2 and three instead puts the motherboard in clear CMOS memory mode. So that is what I did, I moved the jumper from pins 1 and 2 to pins 3 and 4. I pressed power a few times, but I don't think that was required. After 30 seconds or so I put the jumper back on pins 1 and 2. And then when I pressed power the motherboard FINALLY beeped and continued starting up. On first startup it gave a message to the effect of "BIOS checksum error"', so I went into the BIOS, loaded the default settings, saved and went out. (Oh, and removed the floppy drive in the BIOS too, as I did not have one). After performing these actions, the motherboard started up normally and has been working fine for the last few days... here is hoping that it continues that way!! :)

So that is how I solved this problem... hope it helps someone. :)

I have a toshiba m3 laptop, it was going then it froze, so i turned it off, now it wont start up, ac power and the on LEDs light up, if i remove and replace the battery the battery light goes momentarily...


1. Take the battery out of the laptop & try to turn on the laptop using power adapter only. If the computer turns on, then the battery is defective & needs to be replaced.
2. Make sure the power adapter is not defective. Test the output voltage of the power adapter using a voltmeter. Compare the voltmeter reading to the nominal value written on the adapter or the laptop.
3. If you have another processor which is compatible with your laptop's model, try swapping processors & test to see if the laptop will work.
4. The motherboard could be defective & needs to be replaced

Amd phenom faulty


Replace cpu fan , failed cpu fan might have caused CPU stoped working. If you are sure about the CPU fails then replace the CPU. If the problem seems continues after that too, then PC might have failed to boot due to other reasons. What shows on the screen once you power on the computer? There could be , motherboard , or harddisk faults too. Try unplugging other parts and see if the computer boots from CD or USD flash or floppy drive!! Once you know that motherboard works then replace the CPU. There could be BIOS setup problem. Did you check the BIOS for harddisk is set properly.

Hipro HP-d3057f3r computer power supply broken?


I have the same problem. I found this:

http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&dlc=en&cc=us&docname=bph06788&product=12455#bph06788_section_2

  • Replace the side panel, plug in the power cord, and examine the light on the back of the power supply:
  • If the LED is on solid and is not flashing, the power supply is probably good and the problem is most likely caused by a defective component (processor, memory, PCI card) or a defective motherboard. Have the computer serviced, or remove the components and replace them, one at a time, to find and replace the defective component.

    CPU not boot up


    First of all what exactly do you mean by "changed the CPU"? If its the processor? Is only the display not working, since you have said that the fan runs, it means the PC is starting. Check the Keyboard & mouse PS2 jacks. If there is any bent pins in the jacks? If so gently straighten with a pair of tweezers. Also try using a working Keyboard & Mouse from any other PC. If that still does not work, do you see the led lighting up on the MB? Does the MB make beeping sounds? How many? ALso mention the processor you have so that we may be able to help...............sodeep

    Either the new power supply you purchased is not functioning correctly. But, assuming it is now that you are getting some form of power to your PC, it is very likely the motherboard. Whatever fried your old power supply (or it could have just been the power supply itself) most likely fried your motherboard in the process. Probably not the CPU since the MB can't even post.
