My laptop cant load my profile so gives me a temporary profile and cant restore

Can't load profile is a common error. It means your profile is corrupt. You can try logging in under a different profile, if that let's you in you can run System Restore. If there is no 2nd profile to load to, it's time to reload the OS.

go into control panel and create a new user (dont make it the same name as your old profile) then restart the pc and log into that new profile. To retrieve all your settings favourites etc you will need to say what version of windows you are using

Sounds like your best bet is a fresh install of the operating system. Since it is an Inspiron, you may have the option of using PC Restore to re-image the system (Provided previous owner didn't hose the restore)

other things you can do are run diagnostics (Hold Fn Key and Press Power Button) and make sure you don't get a hardware failure in the diags (Passing diags is no guarantee of no faults, just none found)
If all else fails, boot to XP CD and do a clean install of Windows, then load the drivers.

The I6400 is a good system, (I'm writing this on on) but the description you give tells me the OS is hosed and likely a reinstall is your best and fastest resolution.

ok this is what you to do restart your pc then after you restart your laptop press f8 then goto safemode and select admistrator you can find there run you can type there restore

What I would suggest is logging on in safe mode and trying to restore it to an earlier date using system restore. likely the profile is corrupted. By doing a restore back about 4 to 7 days , or before this started happening, will likely fix your issue. If not you will have to purchase the restore cd from toshiba or restoring it from a recovery partition if it has one.

Hi dear do one thing .. restart your laptop …. Pres F8 and go to safe mood restore old date when your date work normally without any problem (Exp: 5 days or one week before like that)
Thank you

Pls give you me a rank as possible

your profile is corrupt. You will need to create a new profile and transfer all your data.

you did'nt give me anymore info so tyr this
once logged in go to control panel and then to user accounts
you can delete user in there
let me know

This sounds like an operating system glitch. Enter safe mode at start up by pressing F8. Once in safe mode, log on as administrator and do a system restore to a point that you recall it allowing you to log onto your profile. This should cure it, if not, let me know and we'll try something else.

Go into safe mode at start up, log in as administrator, and do a system restore. Pressing F8 at start up will take you to safe mode.
