When I restart my computer it begins to reboot, I see the windows logo and then the screen goes blank. The disc drives won't open and it won't respond, but the computer is on. I tried to start it in safe mode or go back to the last working time, but nothing has worked so far.

I assume you're using windows xp with default configuration ....

Can you have the task manager by pressing ctrl alt del .. ? If yes , try end tasking explorer.exe and then starting a new task explorer.exe.

ctrl alt delete doesn't do anything, and every time i go to bios mode the screen shuts off

Is it a blank screen such as the blackness of your monitor, or a blank screen such as the light blue default microsoft background?
