Pc died Not sure if you can help. My second computer does although receiving power does not power up floppy drive,hard drive or cd r/w from mother board. All component work when not connected to mother board, all fans work and system lights. Can you let me know if the board has most likely died or can I try something else.

The hard drive is not loading the operating system. If you have a floppy drive connected and there is a floppy disk in the drive, it won't boot. Remove the disk and try again. If you have no floppy drive connected, then your hard drive is no communicating with the mother board. This could be due to a disconnected power or data cable on the hard drive or the mother board end of the cable. If all the cables check out OK then your hard drive has gone bad.

Step 1:
Which operating system ?

Computer is booting from a non-bootable source. Computer hard disk drive is not properly setup in BIOS. Corrupt NTLDR and NTDETECT.COM file. Misconfiguration with the boot.ini file. Attempting to upgrade from a Windows 95, 98, or ME computer that is using FAT.32 New hard disk drive being added. Corrupt boot sector / master boot record. Seriously corrupted version of Windows 2000 or Windows XP. Loose or Faulty IDE/EIDE hard disk drive cable. Failing to enable USB keyboard support in the BIOS. Many times this error is caused when the computer is attempting to boot from a non-bootable floppy disk or CD ROM First verify that no Floppy Diskette or CD is in the computer, unless you are attempting to boot from a diskette. b> Note: This error has also been known to occur when a memory stick is in a card reader and the computer is attempting to boot from it. If you have any card reader or flash reader make sure that no memory stick is inside the computer. Additionally disconnect all USB drives, cameras, ipods, iphones, etc. from the computer. If you are attempting to BOOT from a floppy diskette and are receiving this error message it is likely that the diskette does not have all the necessary files or is corrupt. If you are attempting to install Windows XP or Windows 2000 and are receiving this error message as the computer is booting verify that your computer BIOS has the proper boot settings. For example, if you are attempting to run the install from the CD-ROM make sure the CD-ROM is the first boot device, and not the hard disk drive. Second, when the computer is booting you should receive the below prompt. Press any key to boot from the CD

Test your PSU power supply unit 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 of restarting or to shutdown or fail to detect/ boot up a computer hard drive

Test all leads that attach to your hard drive power and data cables IDE SATA

the leads from your MOTHERBOARD TO YOUR HARD DRIVE make sure they have a secure dust free connections and are not faulty or just replace them they could be faulty


make sure all leads that are attached to your dvd\cd floppy drives have secure connections and are not faulty or just replace them they could be faulty


computers need power and data to travel through every working device to continue its cycle and have an end so any faulty leads will end up with a computer error


even something as small as a faulty electrical or fan lead can cause you problems

motherboard and a hard drive any leads between them will fail before your motherboard or your hard drive if its a flat ribbon 40 pin type IDE replace it this will be the first to fail

check all electrical power input and extensions make sure they are securely seated even the cd/dvd floppy drives need to have current go through make sure these drives are working

also check the Cmos battery and computer RAM modules make sure they are securely seated with no dust built up or in the sockets on some motherboards cmos batteries are soldered in


check you CPU central processing unit make sure its securely seated and has thermal paste it might be getting to hot the thermal paste will help disperse the heat

Thermal compound is a sticky paste that is placed directly onto the CPU.


Allowing for a more direct heat transfer between the CPU and HEAT SINK and preventing air gaps from forming between the CPU and heat sink.

hope this helps

Possibly the power supply died whilst and caused damage to the system board or video board.
Have you still got the system board manual with the "Beep codes"? that will tell you which area to look. It is likely the video board has crashed.
Hope that helps.

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 they could be 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 or just replace them they could be faulty ?
one bad lead will end with a computer error a computer needs its connections continue its cycle and have an end to function properly

even something as small as an electrical extension or a faulty fan lead can cause this problem follow the troubleshooting procedure a computer needs all of the data and electrical current to travel through every device and to have an end to be able work properly

a motherboard and a hard drive any leads between them will fail before your motherboard or your hard drive if its a flat ribbon 40 pin type IDE replace it this will be the first to fail check all electrical extensions make sure they are securely seated even the cd/dvd floppy drives need to have current go through make sure these drives are working

make sure your computer ram modules are securely seated with no dust in sockets also Cmos battery has charge with no dust in the socket
hope this helps

Here ya go!

Computer is booting from a non-bootable source
Many times this error is caused when the computer is attempting to boot from a non-bootable floppy disk or CD-ROM. First verify that no floppy diskette is in the computer, unless you are attempting to boot from a diskette.
If you are attempting to boot from a floppy diskette and are receiving this error message it is likely that the diskette does not have all the necessary files and/or is corrupt.
If you are attempting to install Windows XP or Windows 2000 and are receiving this error message as the computer is booting verify that your computer BIOS has the proper boot settings. For example, if you are attempting to run the install from the CD-ROM make sure the CD-ROM is the first boot device, and not the hard disk drive.
Second, when the computer is booting you should receive the below prompt.
Press any key to boot from the CD
Important: When you see this message press any key such as the Enter key immediately, otherwise it will try booting from the hard drive and likely get the NTLDR error again

You have two choices:

• Convert your windows 98 cd into many boot floppies. Then install from floppy. There is a utility on the CD (although I can't remember its name. I think it's something like makedisk.exe) that when ran will prompt you for many floppies.
• You can remove the hard drive drive from the laptop, and insert it into another desktop computer. You'll need a small adapter to do this, like the one found here:

1. http://www.pccables.com/cgi-bin/orders6.cgi?action=Showitem&partno=00504&rsite=00504
   
2. Once you have inserted the drive into another machine, you can now copy the files from the windows 98 cd to the hard drive.
   
3. Now re-insert the drive back into the laptop, and boot from the floppy again. Once inside DOS, you can change directory to your windows98 cd files on the hard drive, and simply run setup.exe.
   

The second method takes a little longer, but will give you many other benefits, including never having to insert the cd to install a windows component again. Let me know how it goes.

ok sounds like a bad power supply , i would get a new one

Try plugging the drives into another computer to see if they actually work, ie read discs etc if they do then try swapping the power supply out of your computer.. if this doesn't work then I would say your motherboard is dead. Good luck
