Windows 7 only loads properly after i boot on safe mode previously

Do you have an antivirus software? If so which? Have you tried Microsoft Security Essentials (FREE)? If you want to, disable or remove any old antivirus and install it (You cannot run two AVs together; I am not sure if you can install it in safe mode or not either). Let it update and then do a full scan (will take some time).

If you have no viruses, you can try this: Optimize Windows 7
(remember, no one is asking you to buy anything or to change settings you do not feel comfortable changing. This is just an exhaustive list)

If none of these options work, let me know. Have you previously removed viruses or have changed important windows settings?

Also, I forgot to mention that if you want to uninstall a previous antivirus, you should install first an antivirus uninstaller.

I think a full virus scan might be advisable, for which we recommend Malwarebytes.

You download the free version here: Malwarebytes : Malwarebytes Anti-Malware PRO removes malware including viruses, spyware, worms and trojans, plus it protects your computer

Also, Malwarebytes is recomended, and can be run simultaniously with most other antivirus software, so you do not need to uninstall/disable anything when it comes to malwarebytes (only).

This will get you the task manager functionality back AFTER you remove those viruses: Task Manager - Enable or Disable - Vista Forums

Let us know if anything else has been disabled or messed up by your viruses, and please be careful in the things you click on, like unknown websites or unknown messages from your email (sometimes even hacked known messages). Make sure your antivirus is set to monitor incoming files and the like to better take care of viruses. And installing malwarebytes in addition to your antivirus can't hurt, and may help remove anything still hidden
