Dell Latitude D510 will not boot. Will not boot into safe mode or any other mode. The 9 LED lock is on. Was able to run diagnostic test but would not go into Advanced 32 Bit Diagnostic Test. Goes directly to command prompt. RAM showed fine in test.

Re: Will not boot to Safe Mode
Try to boot from the Resource CD by selecting the <F12> key and select boot from CD/DVD drive. If you tried to run the "Diagnostics" option from the <F12> boot menu and it went to command prompt, there might be an issue with your hard drive or the "Diagnostics" partition is corrupted or missing. If all tests pass using the Resource CD, then your OS is probably hosed. As for the 9 LED light, that just indicates that your numeric keypad is enabled.

Are you able to boot into safe mode by pressing "F8" repeatedly at startup? if so, select "safe mode with networking" and let me know what happens. If you can get into that, you can fix your problem. Also let me know what anti virus program you are running...sometimes they get in the way of things...
try booting to the safe mode, or last known good configuration (F8 At boot)
if you can get to either then maybe try a system restore to a time when the system ran correctly.
You can also run diagnostics by holding the Fn key while pressing the power button on a cold boot
try to boot in safe mode first. when you power on laptop sees dell logo keep tap on F8 then boot safe mode. check if still freezes in safe mode.if yes HDD might causes the freezing issue. if you were able to boot in safe mode. i want you to do this, start>run>msconfig (on the startup tab disable all or uncheck all) then try to restart the computer.
-boot to SAFE MODE
-restart the computer and press F8 and choose SAFE MODE then do the steps below
Windows Update Causing STOP Error 0x0000007E
-For now simple system restore should fix the issue, else uninstall this update by booting to safe mode.
-Uninstalling windows update KB973879 and hiding this update from available update is currently seem to be fixing the issue.
In case if removing update KB973879 doesn’t fix the issue, we need to remove remaining two updates KB970653 and KB972036.
If boot sector of this hard drive resides on block 5842740 then this is a problem. Try followings...
1. Boot with a XP CD, try to repair. OR
2. When PC boots are you able to go to safe mode by pressing F8? If yes, try Good Known Configuration option first.
3. Otherwise boot in safe mode, go to command prompt, type chkdsk and then reboot your PC and let it check disk. If it ask to find sector and block issues and wanted to gic them automatically, accept it.
The led, is indicating that the Numlock is engaged on the keyboard.
If the touchpad stops responding but keyboard inputs work, then the touchpad is either failed or disabled. If the keyboard is none responsive too, then the operating system has locked up and that is an entirely different issue. If the OS is locking up, try booting to SAFE Mode from the F8 menu and see if you can access anything. If still locking in Safe mode, you may end up installing Windows Again. If Safe mode works, then you can check event logs and edit MSCONFIG startup group and the like to find the SW issue
I am thinking that either spyware or a virus might have currupted one your booting files. You need to run anti spyware software and/or antivirus software. Try Windows live one care software this have a 90 free trial version, run it in safe mode and see what happends.
See if you can get to the desktop thru safe mode (hit F8 during boot and choose safe mode (with networking if possible otherwise just boot into safe mode)).
Once at the desktop install and run this program from a CDR or a USB stick. If the program tells you it prefers not to run in safe mode disregard this and continue with teh procedure. If your problem is malware related this will clean it up for you...
sounds like a reload of the operating system, and or your hard drive is corrupt. See if it will boot into safe mode (F8) on startup. You can also run diagnostics on it by holding down the FN key when you push the power button and see what happens.
