I am a home user computer.I have problem when i start up my computer...It log on as usual but when it reach at "Welcome" in Windows xp .two boxes appear and mention that "THE OPERATING SYSTEM WAS UNABLE TO LOAD YOUR PROFILE PLEASE CONTACT YOUR NETWORK ADMINISTRATOR" and InPage Error..I dont know why but the last time i used this computer when it had been stop working for moments and i seem to hang....and i just push the shut down button on the computer until it became dark / shut down

I've had this happen before, because of the hard disk filling up (your C drive). Sometimes the OS will still let you logon, then you can clean up your C drive, then reboot the system and it should work better.
