Check if there's like weird noises coming from the dvd drive (while you have a disc inside). You may also visit support.microsoft.com. You can also google how to delete upper and lower filters through regedit.

Kindly check Device Manager if the driver has been successfully installed. Check if there is a bang (exclamation mark) under Network. Make sure that the downloaded driver is compatible with Windows 7. If this has been done, 1. Go to BIOS and see if LAN has been disabled 2. check if there is a blinking light on the LAN port on your computer. If there isn't, then I guess you may need to change your LAN card.

you might try another keyoard to see if it works

try blowing out all of the dust from your keyboard using a fine air blower from an air compressor making VERY sure there is no MOISTURE in the lines.

dust causes static which causes lots of problems with a computer and its parts

make sure ps2 or the usb lead has a secure dust free connection if applicable

disconnect the keyboard restart your computer then reconnect it the found new hardware wizard should activate

if this does not fix the problem

restart you computer tap the f8 key repeatedly to enter safe mode where the only things working will be your keyboard and mouse allowing you an attempt to repair your computer

If done properly the user should get to a screen similar to the below screen.

Select the option for Safe mode command prompt only

Windows Advanced Options Menu
Please select an option:

Safe Mode
Safe Mode with Networking
Safe Mode with Command Prompt

Enable Boot Logging
Enable VGA mode
Last Known Good Configuration (your most recent settings that worked)
Directory Services Restore Mode (Windows domain controllers only)
Debugging Mode

Start Windows Normally
Return to OS Choices Menu

Use the up and down arrow keys to move the highlight to your choice.
select safe mode
Click start control panel keyboard hardware make sure you have the right keyboard selected
or you might have uninstall the keyboard then restart your computer then reinstall it and its drivers

click start control panel administrive tools computer management device manager scroll to keyboard you might see a yellow question /exclamation mark ? ! or a red X right click update driver

hope it helps

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

the leads from your MOTHERBOARD TO YOUR HARD DRIVE make sure they have 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 drives dvd\cd have secure dust free connections and are not faulty or just replace them they could be faulty a computer needs power and data to travel through every

working device and 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 power lead or fan lead can cause you problems

computers need all of the data and electrical current to travel through every working device and to have an end to be able work properly

make sure ram modules and cmos batteries have dust free secure seatings and cmos battery has charge some motherboards cmos batteries are soldered in

make sure the CPU central processing unit has a dust free secure seating
you can usually do this by pressing the levers down at both ends of the CPU

hope this helps

I think your problem is your memory or video card.

Below are some steps that I recommend.

When you plug in the power cord is there any lights whatsoever on the computer?

When you press the power button do you hear fans running, hard drive spinning, lights on the computer, hear any beeps or lights constantly blinking, hear the DvD/CD drive click and the light on the drawer of the DvD/CD turn on for a second or two? If so the laptop is trying to boot or may have booted, but the screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with the computer and why it is not booting. Most times it's a motherboard issue when you hear beeps or blinking lights continuous. Most times the problem is with the memory or Video Card. Count the Blinking Lights or Beeps and take note of their pattern (1 Long or 1 Long followed by 2 Short).

Maybe your power cord is bad if you don't get anything to happen whatsoever when you press the power button.

Maybe you have a Static Charge Buildup. Remove the Power Cord, then Press and Hold the power button for 30 seconds. After 30 seconds plug the power cord back in and hit the power button to see if it boots.

Maybe your memory is bad or the memory slot is bad.

Remove the Power Cord, Open the Case and remove one of the memory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x on it with an ink pen. If it fails to boot then move the chip to the next memory slot and try rebooting. If it fails take the chip out and set it aside, then put the other chip in and try booting it in both slots. If it boots, just to verify that the chip set aside is bad, mark an x on it and put it into the open memory chip slot and try booting.

Maybe your power supply is bad. Sometimes there is enough power to make the power light or some other lights come on but not enough power to make the fan turn on or hard drive spin.

Below are links and info I found from Dell's Website based on your model.


Controls and Lights Front of computer:

Power button - push button

Power light
green light - Blinking green in sleep state; solid green for power-on state.
amber light - Blinking amber indicates a problem with the power supply inside the computer. If the system cannot boot and there is a solid amber light, this indicates a problem with the system board (see "Power Problems" in your Owner's Manual).

Diagnostic lights
four lights on the front panel (see Diagnostic Lights.)

Standby power light
AUX_PWR_LED on the system board

Hard-drive activity light
green light - When the computer is reading data from or writing data to the hard drive.

LAN indicator light

green light - Solid green indicates that a LAN (local area network) connection is established.

Its all because virus try to install a latest antivirus in this & scan ur computer it will solve ur problem

Dell Dimension... | Answered on Apr 11, 2012

Nope. you cannot access your files. even if you use a external hard dive to access the files.

i suggest you install windows 7 in your computer but do not reformat the hard disk . in that way your files will still be saved in your harddrive.
Once you have access to your files i suggest you save them in a flash drive or external hard drive if you have one. then reformat your computer and install a windows xp.

here is a tutorial on how to install windows 7 without reformatting your harddrive.

Goodluck. If you have any success using my solution please give me updates.. Thanks

There is no other way to power up the computer. The green light inside the pc don't mean it is on, it can be only the network card led (that is always on). I suspect a defective unit. Try holding the power button for some seconds if it's booting up.

Dell Dimension... | Answered on Mar 01, 2011

Assuming that the power supply that was replaced was the proper wattage and physical size, go ahead and disconnect all of the plugs, boards, memory chips and anything else that is connected to the motherboard. Connect only the power connector main and the cable that allows you to power the system off and on, then press the power button. You should get a beep-code from the mother board telling you that there is no memory onboard (make sure there is a speaker either attached to the motherboard or connected to it via the speaker connector.) If you get no beep, the motherboard is probably bad and will need to be replaced. If you get a beep, start connecting items one-by-one until you find the one that won't let the system power up, that's your bad part.. Good luck and I hope this helps.
