I fixed the no desktop/startmenu load up problem.

This is how it goes, it seems to be a DLL change wich causes your computer to read wrong iformation causing the load up to stop since it keeps on reading wrong data. It's very easy to fix pay attention! If you can get to another pc, find a program called "registry fix" via limewire etc. Burn the program on a cd and boot it on your messed up computer. Then press CTL+ALT+DEL to open the task manager. From there go to My Computer and go to the CD drive. Execute the program you burned and install it. After that run the DLL scanner and it will find the invalid DLL and fix it. After it's done restart and I assure you your pc will work and run smoother.

Registry fix is a good program because you can back up your registry in case your computer fails.
