If you mean the PSU, have you checked the cables from the PSU are actually plugged in correctly to the drives? (it's been known for folk to plug them in the wrong way). With regard to the monitor, check your graphics card (if not onboard) is still correctly plugged into the board (remove and re-seat it), and that the monitors cable is correctly and securely plugged into the VGA port.

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 will help don

I have a foxconn n15235 and the problem is my system only comes on very occasionly.wut could be wrong?


It might be the power switch itself. I've seen them become intermittent, but it's not a frequent problem.

A more likely cause would be the power supply. Unless your computer uses a proprietary power supply (as in some very small cases, for instance), you can easily change the supply. You might be able to borrow one from someone to try and see if your system starts reliably. This is what I see most often; in fact, I just replaced a supply for a friend whose computer was randomly shutting down or would not start up, just like you describe.

The motherboard may be bad. When you press the power button, you're signalling the motherboard which then signals the power supply to turn on. It's possible the motherboard isn't always working correctly.

You might have a hard disk or optical drive connected to the motherboard that is causing this. Disconnect the cables to all the drives from the motherboard and see if the system starts more reliably. Of course, if you disconnect the hard disk the system won't start your operating system, but right now you just want to see if it turns on.

It can be a frustrating process to find the trouble, but you'll fix it. Try the power supply first. Good luck, and thanks for using Fixya!

In my opinion Motherboard issue, but I can't assure, it could also be the Power supply, as bad power supply could cause the motherboard mal-function and is causing the hard drive failure. If the motherboard is under warranty, you better get a replacement than wasting another Hard drive, and I hope it's better for you to replace the power supply as well, you'll spend less buying a 450watt power supply than buying a new 500gb hard disk.

Also make sure the cabinet is properly fitted and the ground is working without any problem, you can check this by using a tester (screw driver tester) after it's connected to the mains, or you can try with your hand (it'll not kill you :-], but I don't recommend if you have a screwdriver with tester).


If you need further help, let me know.


Good luck.

Thanks for using FixYa.

  1. Make sure the CD/DVD drive is connected and has power.
  2. You didn't say if the drive is IDE or SATA. If it is IDE, make sure the BIOS has IDE enabled.
  3. Check the 'boot order' in the BIOS and make sure the CD/DVD drive is first.

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.

Ms 6787 no signal input


since you said you do not know anything anything about the jumpers and stuff, probably i suggest you take it to a nearest computer specialist to do it right for you. one thing you have to check up when installing a new motherboard is you power supply, does it have more or less power output? is the local disc or hard drive connected correctly? if you have no idea on all of this then there is a need to have a specialist to do it right for you becauase if not, there would be nothing for you computer to display.

looking forward to hear from you.

thanks,

Blank screen on start up


Try removing all cards with the exception of the video. Remove all memory leaving (1) to boot from.
Disconnect power and reset the processor.
If you have a boot disk or copy of XP on disk, try to boot from the CD or DVD.
If the unit boots at all the problem may be the HD.
If not try downloading the BIOS update for your chipset.
Remove all extra drive, like secondary CD or DVD drives, Floppy or Zip drives.
You may have burnt the processor but I don’t think so.
Power supply is OK or you would not power up. Their are 3 or 4 supply voltages from supply, +- 12 volts, +- 5 volts and +-3.3 volts.
You may have a secondary 12 volt 4-pin plug but that is for on board video.
Try a boot disk and flash your BIOS, if you can.
Hope this helps.

Boot failure Asus P5Q-EM


Disk boot failure. Issue:Disk boot failure.
Cause: This issue could be caused by any of the below possibilities.
  1. Boot options are not set properly in CMOS
  2. Non bootable disc or USB in computer
  3. Remove added hardware /check connections
  4. Hard disk drive is bad
Solution:Boot options are not set properly in CMOS
Verify that the boot options within CMOS are set properly. Below is an example of how we recommend the boot options be set. Additional information about how to enter CMOS can be found on document CH00192.
  1. Floppy drive
  2. CD-ROM drive
  3. Hard Drive
  4. Other / Network
Non-bootable floppy diskette or disc or USB in computer
Verify that there is no floppy diskette or disc in the computer. If the boot options are set improperly the computer could be trying to boot from the disc drive instead of the hard drive.
In addition to verifying there is no disc in the computer make sure that no USB jump drive, external hard disk drive, or memory stick is inside any memory card reader.
If you're wanting to boot from a floppy diskette, CD, DVD, or USB drive and are getting this error message and have verified that your CMOS settings are in the proper order as explained in the above paragraph the diskette or disc you're using is either bad or does not have the proper files on it to make it bootable.
  • Additional information about how to make a boot disk can be found on our boot disk help page.
  • See document CH000669 for information about creating a bootable disc.
Remove added hardware / check connections
If you've recently installed any new hardware it's suggested that it be removed to verify it's not causing this issue. If after the device has been removed the computer works and it was another IDE / EIDE device ensure that the jumpers are properly set on the hard disk drive.
In addition to removing any new hardware it's also suggested if you've recently moved the computer or installed anything inside the computer that the connections for the drive be checked. Usually it's best to simply disconnect the cables from the back of the drive and reconnect them to make sure they're connected properly. While inside also disconnect and reconnect the cable connected to the motherboard as well. While inside your computer make sure you're aware of ESD.
Bad hard disk drive
If you have followed the above steps and you continue to experience the same issue, unfortunately it is likely that the hard disk drive is bad or the controller is bad.
If available, you may want to connect another known good hard disk drive to the computer to determine if it can be detected. If it is able to be detected then replace your hard disk drive. If it is not detected, unfortunately you will need to replace the motherboard or controller as it is bad.
If no additional hard disk drive is available it is recommended that the hard disk drive be replaced first or that the computer be serviced / repaired.

No activity on startup. Only fans spin up.. No video signal.


You may clean the memory board and video card connector with pencil easier and with alcohol the connectors and reinstall it. this will work. or you need to replace the power supply the orange wire 3.3v might be missing or red+5v, white-5v or the purple wire +5v
