My tj media 304p does not complete boot up of system. When turned on, says SYSTEM BOOTING on screen then turns blank. what is wrong?

ITS EITHER A HARD DRIVE OR A MEMORY ISSUE

SOURCE: booting up

Probably corrupt firmware. You can re-load the backup and restore the system.
Press and hold the SOURCE and STOP buttons whilst plugging into the mains supply.

Continue to hold until recovery option appears.

If this doesn't work, then the backup firmware is corrupt too.

Thanks for the suggestion, I have finally found out that the back light for the monitor is culprit. Also dell people and confirmed it . They aggred for a replacement. Thanks for the suggestion again.

As the notebook is starting you see the Dell 'Splash' screen. Press F2 to go into the BIOS setup. Check to make sure two things: first that your cd/dvd and hard drive are being recognized and identified, second that your boot order has the cd/dvd first and internal hard drive second. Your machine may be trying to do a USB device boot or network boot when these options are not available. Next try pressing F8 immediately after the splash screen disappears to try to get into Safe Mode. If it still fails to boot, I would try booting using a Windows XP installation disk and then going into the repair console to check if the hard drive is damaged or corrupted.

looks like it's unable to find the harddrive to boot from. It's trying to boot from a network location now.
Try entering the bios and see if you have an option to run a scan on the harddrive
Also check the boot options - make sure that it starts from the harddrive BEFORE it tries to boot from network.
