of the boot process.
If the hard drive
is not being detected in the BIOS or sys hanging at P.O.S.T., try the following steps.
-
Before troubleshooting there is specific questions you need to answer
Click here for the questions.
-
Do you have an
ATA PCI card. If you do, the hard drive won't be detected in the BIOS because
it is attached to the card. That is normal.
-
Set the BIOS to
default and clear NVRAM
-
Reseat the
IDE or SATA cables.
-
For IDE drives, make sure your master is on the end of
the cable. The secondary or slave is connected to the middle of the cable.
-
For SATA drives, the master drive is connected to
motherboard SATA connector 0 or 1 (depending on the
lowest number. Some systems the SATA is numbered 1 and 2 (1
would be master in this case). Others is
numbered 0 and 1 (0 would be master in this
case)).
-
Reseat the
power cables.
-
Make sure the
jumpers are set correctly.
(This is for ATA hard drives. SATA hard drives does
not have jumpers)
-
Remove the PCI cards.
-
If you have a second
hard drive,
disconnect it.
-
Disconnect the
CD-ROM
drive(s) and
floppy.
If the system works with them disconnected then either the CD-ROM or Floppy
is causing the issue. Try putting them back one at a time till the problem
comes back.
-
If you have another hard drive, try that hard drive in
this system. If you have another system similar to this one, you can try the
hard drive in that system. (has to be the same chipset
on the motherboard like this one or it will error out) If it works
you know it is not the hard drive.
-
Run diagnostics on your
hard
drive. (See the manufacturer of your hard drive
for the utility)
-
Use the
Software Troubleshooter.
