INSPIRON 1545 - ERROR CODE 0146 - PLEASE HELP!

My Dell Inspiron 1545 does not start up completely, it gets to my login screen (the screen where i enter my password for my account) but the only thing thats not loading up are the 2 accounts that are on the computer so i cant get past that screen cuz i cant login anywhere. The laptop turns on and runs the exact same way as it was when it was working, its not taking long to power on or anything like that, the only thing is that my accounts dont show up so i dont know how to fix that

I ran the diagnostics and the only thing that popped up was the message saying the error code 0146, I continued running the test after seeing that message and everything passed.

My laptop was restarted back to factory reset like 2 months ago, i didnt have any cd's to reset the computer with but so after the factory reset the laptop was going slow so i was trying to change the settings to run faster and for programs not to run in the background and i found the settings to change which programs and stuff will automatically run when the computers starting up and i turned them all off,

Did i turn off the settings to get my accounts to load on the login screen when i first turn the computer on?

How can i get the accounts to load on the login screen?

How can i fix the error code 0146?

I tried to reset it again but it doesnt work, i tried resetting the startup setting back to default and it didnt work, i dont know how to get into safe mode cuz i push F8 at the right time and nothing happens

How can i get my computer to work again? I had just reset the computer back to factory reset so i dont have anything on the computer so resetting it again is not a problem, i just cant get it to reset
