having trouble starting up my computer

They use Atom Processors and are radically different to a Note Book.

Try starting in Safe Mode and log into the Administrator Account to see if that works. If you can log into the Admin Account as apposed to your User Account you should be able to create a new user Account and see if that works.

It's most likely that the User Account has become corrupt here.

Of course this is assuming that this is a Windows OS and not some form of Linux which was a option on some Eeee's. If you have Ubuntu of some kind installed that's a radically different kettle of fish.

Just as stated above, some more information would be helpful. Are you running Windows XP, Windows 7, Linux/Ubuntu?

If you are running windows, there was a virus that would mess with the unserinit system file and would cause the computer to logon loop. Every time you would logon, it boots the desktop and then immediately logs out. If this is the case, you can attempt to repair it by using a LiveCD of some sort, repairing windows, or best case scenario is wiping and re-installing windows, and then of course setting yourself up with some mal-ware protection. **Be warned if you wipe the computer and start over, you will be losing your documents unless you can get into safe-mode first and back them up **
