Monitor not working after adding drivers

Go to GOOGLE and type DRIVERS for your exact product and model of monitor, which will hopefully give you the correct drivers to download. Softonic would be one place to look. CNET would be another.

May i know the model and the make of the product in details so that it can help me resolving the issue is a more prompt manner

According to the Dell Support web site the Dell Dimension 2400 has a built in Intel 3D extreme graphics adapter, assuming you are using this and not a PCI graphics card.

Go to the Intel Download Centre and run their Intel Driver Update Utility which will automatically scan your system for updated drivers for any installed or integrated Intel devices.

If the Intel Utility identifies an updated driver for your graphics adapter then download and install that which should enable you to configure a higher resolution for your display.

Have you tried some external powered speakers or even some headphones?
The problem may just be a dead speaker in your case or even a loose or misplaced jumper wire from the speaker to the motherboard.
Good luck, hope this helps. Post back if you're still stuck.

Please download the sound driver at : www.nodevice.com/driver/company/Dell/SOUND.html www.notebook.driversdown.com/notebook-drivers/r_1_1.shtml

If you have another monitor for desktop hook other monitor up then under hardware and software in control panel, add the dell monitor, then hook it up. Some operating systems need the driver to be added first. My brother almost threw away agood dell lcd monitor before I told him this, now he loves the lcd, works great.

you can push every lamp from 19inch monitor who have same jack for conector{i work that, i have dell1900fp}!!!sorry for eng.good luck

try swapping the computer power cable and don't connect the vga cable with the system. if you get a power on self test displayed it makes sure that the monitor is fine. if nothing is displayed you can take it for repairs or else call 1-800-624-9896 its Dell technical support number or log on to support.dell.com

when the screen goes away try to wigle the cable from the computer to the monitor see if it could be that

I used Everest home edition to find the wireless drivers for my DELL C640 laptop.   The wireless card in it is an  ntel PRO/Wireless LAN 2100 3B MiniPCI Adapter (IBM). I've downloaded the wireless driver from Intel's website, here: 
http://downloadcenter.intel.com/filter_results.aspx?strTypes=all&ProductID=944&OSFullName=Windows*+XP+Professional〈=eng&strOSs=44&submit=Go!#DRI
It's the 3rd result in that search page. If the link doesn't work, simply search for Intel® PRO/Wireless 2100 Network Connection on Intel's site. 
That Dell C640 wireless driver works fine for me, I'm using the wireless card to type this :)    
good luck!
