Logon error?


Unfortunately I have repaired a number of these and all had to have the OS reinstalled. It is caused by a virus that removes the logon page and though windows recognizes that the password is correct, cannot process it.

I turn on my compaq presario c300 and it immediately take me to an enter power-on password screen


Hello,
A password on boot is not set by default. The owner activates this option. If some prankster or michief maker has entered a password on boot on your computer without your knowing it, there is nothing you can do, save taking the machine to an HP Certified Service Center to have the password removed or reset.
As the password on boot is a deterrent against computer thefts, you might be asked to show proof of ownership. This certainly is the case with Toshiba laptops.

Hope it helps.
