Hi my Dell Inspiron 6400 is working in safe mode but will not boot up in the normal way, it goes to a blue screen and explains Registry file failure, the registry can not find the file...contact administrator. I ran some type of diagnostics and got an error code 0f00 136c. This did happen a few weeks ago but i kept trying and it all of a sudden started up but this week i must of tried to boot 10 times a day with no luck, only safe mode! can you help?

this is a known problem with Windows XP. it occurs as a result of a corruption within the Registry hive.

A very thorough and complete set of instructions can be found here- http://xphelpandsupport.mvps.org/how_do_i_repair_a_stop.htm

Dear, Requested data was not in memory. An invalid system memory address was referenced. Defective memory (including main memory, L2 RAM cache, video RAM) or incompatible software (including remote control and antivirus software) might cause this Stop message, as may other hardware problems. What you can do is if you have more than one memory modules, you can boot the system with single and see. If this is due to memory leakage issue, you can find it here

If you still have your recovery disk, this would be the time to use it. turn on the laptop and open the dvd/cd drive asap. Put the cd in then restart.

You need to cheat a little. First try to boot into safe mode by pressing the f8 key as soon as you hit the power (and keeping your fingers crossed on the other hand that it notices your doing this). Before you get too depressed just try booting into safe mode and then reboot normally. That may be all it take to fix it. Try this a few times before getting into the more serious fixes.

If you can get into safe mode you can simply copy your files off to a usb data drive. Those will still work. You may be able to use the wired network card if you select safe mode with network access. But don't count on that. The cd/dvd will not work so you can't burn it to disk. A flash drive will work on the usb while a external hard drive that connect via usb usually won't as it needs drivers.

The other way is to boot using a bootable cd. If you can get a vista install cd you can install over the top of your existing windows and retain your settings. If you don't know where everything is then you need to be a bit creative and use something like the demo Ubuntu cd that boots into a windows like operating system that will allow you to copy stuff over the network to the usb drive or the network.

If you have a friend with the right laptop or desktop you can take the drive out and set it up as a second drive. When they boot normally they then can see your drive and just copy burn or move your stuff. This is what I do in the shop when the existing system is too messed up to work with. There may be the odd thing you won't get access to but you should get most of it.

Keep pressing F8 as the computer starts up, select "last known Good Configuration" from the menu.

Hi,

Have you installed any application/program prior to the blue screen? Most blue screen causes your system not to boot to your operating system anymore. It is possible that your hard drive is crashed due to a virus infections or spywares. Incompatibility and corrupted system registry may affect your system to have blue screen as well.

You may try the following steps below.

1. Restart your computer. After you pressed the power button to restart. Keep on tapping F8 key on the keyboard on and off.

2. Boot advanced option will show up on the screen. You may boot your computer to the following option.

a. Last known good configuration
b. Safe mode with Networking.

If Safe mode w/networking works, restore your computer to an earlier using the system restore features.

Keep me posted.

Regards,

jeff

Try "Safe Mode" (holding F8 key on boot and selecting "Save Mode"), then run diagnostics and an up to date (virus definitions) Anti-Virus full scan.
If Safe Mode is not accessible then you may want to consider a format and clean install by booting to your Windows (?) CD.

First try to boot in the safe mode, by repeatedly pressing the F8 key. If it boots into the safe mode, press the start button, shut down then select restart. If it will not boot normally then, repeat booting in the safe mode and once booted go to programs/accessorys/system tools/restore the select a restore point date that the computer was functioning correctly and restore for that date. If it will not boot the safe mode restart the computer with the system cd disk and restore from it. BPCS
