LEDs indicate a memory error

Reseat RAM and try modules one at a time. If ony 1 module, replace it

I recommend you to update your video drivers.

Inspiron 6400 Battery,

Laptop batteries normally just last for a few years, depending on usage. If your battery is almost done, it may report a 'full' status, but just have the capacity to feed your laptop for a few minutes.

You may check this by disconnecting current while your laptop is started up. If low battery capacity is the cause, the same will happen within a few minutes.

Laptops normally go in standby on low battery, to avoid data loss.

ok after you have booted in safe mode do a restore to a date just before the last day it worked properly and try that restore is found here

start/programs/accessories/system tools/system restore

hope this helps

Tap the f7 or f8 key, when you turn it on, it should go into safe mode, Go into start programs, accesories, tools, and restore, select restore, select a date closest to today and let it go through the restore pocess, if it suceeds and starts up, rub a good virus program right away, it sounds like you picked up a virus or trojen, just be patient and it shoul be ok, if it won't go into safe mode, let me know, that will require more work. And before you do anything, unplug, remove the battery for a few minutes and replace, try it and if it still won't run, do the above, thanks ,GYM

bad display drivers, boot into safe mode (F8 on boot) it should let you use the computer, unistall the graphics drivers and reboot again in normal mode, when your in re-install the graphics again

regards

well what you have on your computer is the computer does not find your hard drive where you have the operative system thats why is asking you to boot from cd because the computer wants to instal a operative system may be your hard drive is damage ok lets do a test turn on your computer by presing the power botton and then press the key to boot on bios page can be (delete ,F1, F10 ) any of those every time you try to do the boot up if does not go to bios you have repit the same operation so when you get bios system display on you computer look for the hard drive and the boot order if there is no hard drive so your hard drive is damege and you have to reolace for a good one and instal the operative system
