According to the Dell support site, this is a possible motherboard failure. The suggest corse of action is to disconnect all interal and external peripherals, with the power off and disconnected. This would include the printer, scanner, ext. drive, monitor, interal dvd drives, extended graphics card (if installed), ect. I would leave the memory and hard drive in place for now. If the comuter boots up, turn it off again and add the monitor to the mix (on the integrated video card). Then add one peripheral at a time and repeat till you find the bad part. If the computer is still giving you the error, it is most likely a bad motherboard, and that will need to be replaced. If you are not computer savy enough to do this, take it to a computer repair shop to get the work done.
It's unlikely that you're doing something wrong. Did you buy this DVD player as one that is supposed to support connecting hard drives? If not, then the player probably doesn't support connecting a hard drive.
the beeps are post during post the very first work is done by the ram,all the memory in the ram is first transferred to the hard disk,and remains active untill turned off. the grrr is the sound its not getting enough power test your PSU power supply unit or replace it if the fan is not working the PSU is faulty One bad/faulty lead can cause a computer with lots of problems replace all the leads that attach to your hard drive including electrical extensions + IDE,SATAthe ones that attach from your motherboard to hard drive 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 are probably old and faulty ? hope this helps

A Computer Motherboard Diagram
Once you know what you are looking at, you can recognize the components on any motherboard layout. A computer motherboard diagram is very useful for when you need to replace motherboard, do motherboard upgrades, troubleshoot motherboard, or build your own computer.
PCI Slot - This board has 2 PCI slots. These can be used for components such as Ethernet cards, sound cards, and modems.
PCI-E 16x Slot - There are 2 of them on this motherboard diagram, both are blue. These are used for your graphics card. With two of them onboard,
you can run 2 graphics cards in SLI. You would only need this if you
are a gamer, or working with high end video / graphics editing. These
are the 16x speed versions, which are currently the fastest.
PCI-E 1x Slot - Single slot - In the PCIe 1.x generation, each lane (1x)
carries 250 MB/s compared to 133 MB/s for the PCI slots. These can be
used for expansion cards such as Sound Cards, or Ethernet Cards.
Northbridge - This is the Northbridge for this motherboard. This allows communication between the CPU and the system memory and PCI-E slots.
ATX 12V 2X and 4 Pin Power Connection Power Connection - This is one of two power connections that supply power to the motherboard. This connection will come from your Power Supply.
CPU-Fan Connection - This is where your CPU fan will
connect. Using this connection over one from your power supply will
allow the motherboard to control the speed of your fan, based on the
- This is where your CPU will plug in. The orange bracket that is
surrounding it is used for high end heat sinks. It helps to support the
weight of the heat sink.
Memory Slots - These are the slots for your RAM.
Most boards will have 4 slots, but some will only have 2. The color
coding you see on the motherboard diagram is used to match up RAM for Dual-Channel. Using them this way will give your memory a speed boost.
ATX Power Connector - This is the second of two power
connections. This is the main power connection for the motherboard, and
comes from the Power Supply.
IDE Connection - The IDE (Integrated Drive Electronics) is
the connection for your hard drive or CD / DVD drive. Most drives today
come with SATA connections, so you may not use this.
Southbridge - This is the controller for components such as the PCI slots, onboard audio, and USB connections.
SATA Connections - These are 4 of the 6 SATA connections on the motherboard. These will be used for hard drives, and CD / DVD drives.
Front Panel Connections - this is where you will hook in the
connections from your case. These are mostly the different lights on
your case, such as power on, hard drive activity etc.
FDD Connection - The FDD is the Floppy Disk controller. If you have a floppy disk drive in your computer, this is where you will hook it up.
External USB Connections - This is where you will plug in external USB connections for your case or USB bracket.
CMOS battery - This is the motherboard's battery. This is used to allow the CMOS to keep its settings.
To remove or change the Windows password is not easy to do, but can be done with Linux Password Removal program. You need a computer savy friend to help you.
The other way is to install Windows from scratch again to get a working laptop again but you may lose your data. There is a way to retrieve your data before you install Windows again.
If you didn't protect the hard drive with a password and if you did and still know your BIOS password, THEN go into the BIOS setup and remove the password on the hard drive first.
Then remove the hard drive from the laptop and connect it to an USB hard drive adapter. Insert the adapter into a working computer's USB port and the computer will see this as an external hard drive. You can then open the folders and view your files. Copy the various folders and files you require to a USB memory stick and/or burn these to a CD etc.
Now you can return the hard drive back to the laptop, install Windows, the device drivers, your programs and copy the data back into the laptop.
It pays to backup your data regurarly because if the hard disk fails and this can happen unexpectedly, you will lose your data.
One of your memory slots might be bad as I'm assuming you tried both memory chips in the known working slot.
I found setting the boot up sequence in BIOS is better than using F12.
Set your BIOS to boot the CDROM first. I suspect the hard drive has failed or has a problem. Do you have a floppy boot disk? Lenovo has PCDoctor bootable diagnostics on their website. You may have inadvertently bent a pin inserting the hard drive. Your CMOS battery could be dead but since that was untouched I would be surprised.
Depending on how big the knock was it could have been severe enough to damage your hard drive. The boot up of the machine hence the fan is caused by the CPU heating and the fan cooling it however when the bios and CPU ask the hard drive to boot up it cannot thus that is the failure of your startingup. It may need the attention of serviceman to repair it and even he may suggest a replacement of the hard drive.
