My asus Eee pc 900hd will not start up it goes to, select safe mode, safe mode w/ networking , safe mode command, last configuration that worked and start up normally. there is a blue screen after the widows starts up.I just want to reboot it.

OS is corrupted and needs to be reloaded.

insert windows disc to your dvd drive and use repair your computer option.

fist off all you go to the BIOS and change boot order (as fist boot device CD-ROM) then try again.

Reinstall or repair Windows installation. After that check for viruses.

as soon as you turn your netbook on, keep tapping F8 until another screen pops up, then select start up repair, If no problems found and doesnt work. repeat the process but choose safe mode with networking, then click start and shutdown, try and reboot as normal, If doesnt work. Select safe mode with networking once again by repeatedly tapping F8 as soon as you switch on your netbook. Please download tdsskiller.exe (exe not the zip) to your desktop using this link at the end. Once downloaded please double click to install. Once installed open and run a scan, once scan complete, select cure and then rebsart your system, start system normally and that should solve the problem http://support.kaspersky.com/viruses/solutions?qid=208280684
Please rate if helpful, thanks. P.S tdsskiller is a freeware and will not cost you a penny.

its mainly due to inproper shutdown. your hard disk needs a scan and after that format and reinstall windows!

Now that PC works in Safe mode i suggest you to run the Disk Check.

Step1: Double click on My computer and then right click on C drive.
Step2: Choose properties and then click on tools option.
Step3: Click on the Check Now tab listed under Error Checking.
Step4: Select both the options under "Check Disk Option" then click on start.
Step5: It will prompt you to restart your computer.
Step6: The Disk Check gets initiated as soon as you your computer starts rebooting.
Step7: Allow it to finish.

Hope this helps.

There are many reason for a system goes to safe mode directly.here is the solution to solve the issue

Follow the steps:

Immediately begin tapping the "F8" key when the reboot sequence begins (make sure your "F Lock" key is activated.) Once the black "safe mode" screen appears, then first try selecting the option "Start Windows Normally" using your mouse or keyboard up and down keys. Allow Windows to boot, log into your profile and wait for the program to fully configure. Once that is completed, go to the "Start" button and select "reboot." If all is well, the "safe mode" will not reappear.

If that fails, then repeat the reboot sequence -- tapping the "F8" key repeatedly -- and when "safe mode" reappears, choose the "Last Known Good Configuration" selection and allow it to go through the same sequence as in the above paragraph.

If the above does not work and your system continues to first boot into "safe mode" it is possible that a setting in the boot configuration file is checked.

For that go to start -> RUN and Type in "msconfig" in the provided box and hit "enter." The "System Configuration Utility" will appear. Using your mouse or right arrow key, select the "BOOT.INI" tab. Look for the "boot options" section and the "SAFEBOOT" selection box. If it is checked, uncheck it, select the "Apply" button and then "OK."
Go to the "Start" button and select "reboot" and your machine should now boot directly into Windows.

Try restarting your notebook and hit the "f8" key after you see the first screen come up. Keep hitting the F8 key until you see a menu that says "start in safe mode" start in safe mode with networking......
Start in last known good configuration....Start windows normally.

Try using Start in last known good configuration.

Hopefully, that will solve the problem that is hanging up your windows from starting.

if a blue screen pops up with white writing theres something seriously wrong with your laptop a blue screen on a computer is the worst possible thing that could happen apart from the thing actually exploding and can be caused by a wide range of things, my suggestion would be to reinstall windows as it will basically give you brand new computer with no errors
