restart your computer repeatedly tapping the f8 key to enter safe mode while the screen is black once in safe mode where the only things working will be your keyboard and mouse allowing you to attempt to repair your computer


you could select the option start at last known configuration that worked this will tell you if and what file has been corrupted or missing then you will know if its a hardware issue

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 might be faulty


if its a 40 pin flat ribbon type it will be the first to fail


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 something as small as a faulty electrical fan and its lead can cause you problems

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


make sure your graphics card is securely seated with no dust built up or in the socket

if you remove your graphics check the socket to make sure its dust free


restart your computer then reinstall it this should activate found new hardware wizard


hope this helps

PL19Wb Monitor: montior is still showing power is on but screen go...

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Dimension4700 desktop: replace read-only dvd dr. with dvd burner?

I've had a lot of luck with www.newegg.com.
Do some searching, see what fits in your price range, and read the reviews. www.tigerdirect.com is also very good. Check their return policies for restocking fees, in the event that you're not happy with your purchase.

Here are the instructions for removing and replacing your particular optical drive:
http://support.dell.com/support/edocs/systems/dim4700/sm/parts.htm#wp1054337

Make sure you buy an IDE drive, not SATA.

Good luck! Hope this helps! If so, please leave a rating!

I have no picture on my flat screen montior im using a older montior and its works

If the monitor light comes on but you get an "out of range" message, you'll have to start the computer in "VGA mode". Probably your video card is set to a resolution that the monitor won't display.
Just a thought, as you didn't say anything but you don't have a picture.
If this doesn't work, check the power and cord and video cable before you declare it dead.

Power on - blank (black) screen

Disconnect the monitor signal cable from PC and switch on your monitor. It should show some logo with Red, Green and Blue colors with a message similar to "No signal". If so, your monitor is working fine. Sometimes if the brightness and contrast is set to zero using controls present in the monitor, it will not show up anything. check wheather somebody set your monitor brightness and contrast to zero. If so incease them. As a last try connect to different PC and check before approaching a service center. I hope this will help you out. :)

External montior is blank

Are you sure the laptop is powering up?
Do you hear the laptop boot up and the hard drive spinning and the power LED is on when you connected the external monitor?
The monitor must be powered up before the laptop for the video info to switch video port automatically.
If the external monitor is blank then you can't make it work, your video card is faulty and it is not possible to replace as it is built-in on the motherboard. You could replace the motherboard but this may not be a cost effective solution,

Montiors shut off

if the monitor goes into standbye when you plug it into the computer , it generally means there is NO signal coming from your video adaptor.
Plug the old monitor in , if it works, ide suspect the new monitor(s) are not working correctly.
if it doesnt work , you need to restart the computer in safe mode by repettitively tapping the f8 button as the computer starts, before it says "starting windows".
If you have a signal on your monitor in safe mode, then most likely you have a bad or corrupted video driver and it will need to be updated.
if you have no video in safe mode , you will need to remove the cover and physiclly check that all add-in card power cables and memory chips are squarly seatied in there slots. MAKE SURE YOU UNPLUG THE COMPUTER AND DISCHARGE ANY STAIC BUILDUP IN YOURSELF BY GROUNDING (TOUCHING) SOMETHING METAL BEFORE YOU TOUCH ANYTHING INSIDE THE COMPUTER.

AFTER YOU CHECK THESE THINGS AND TRECONNECT THE POWER AND TRY TO START......POST AGAIN HERE

No composite input signal

`Hi,
If the monitor is making the noise , the monitor circuit baord has gone bad.
If you have purchased the monitor on a seprate order from dell it would be covered under 3 yr warranty. If the same has been bought with the Dell computer , it would hold the computer warranty. would request you call the manufacturer.

Before you call Dell , you can try the following things
1. Disconnect call cables from the back of the montior
2. Press the power button a couple of times in the front of the monitor to drain any resident charge
3. Reconnect the power cable
4. check if you see the monitor self test running and if the noise is still there with there

Thanks
