text: my computer hangs at startup?   press f8 while it is starting, need to get into safe mode.  i would recomend you try to fix your registry. you might have deleted dll, wrong paths, and even malware in your registry that causes your computer to look for things that are not there and continues to use resources. delete programs you are not using with the remove programs from the control panel. then delete the folders they where in. if you just delete the folders without doing the uninstall you defenitely have registry problems. run ad-aware, spybot and and antivirus program.  then re-run the registry fix program.  scan disk and then defragment the hard drive.
