Help! My computer keeps freezing when I start it up, I can't even log in -_-.?

In order to fix computer freezing at startup, you must first boot up your CPU in safe mode. This is done by tapping F8 as soon as your start your system.

Once in safe mode you can attempt to fix the problem. If you don’t feel like going to the computer repair shop or buying a new system, the next best thing is to scan your computer with a registry repair program.

Computer freezing comes from errors within the Windows registry. I would recommend cleaning it up. You can perform a free scan at:
