I got an acer tower with an hp monitor how can i reboot it without a disk



What do you mean by "reboot"?
What OS is this?
 


Please explain your situation better.
Without using the word "reboot", what exactly are you wanting to do, and why?
 


Computer frezzing up and stuff and i need to crash it
 


Have you tried turning it off, and then on again?
 

Yes
 
Well...with the level of info you've given us on your problem, it is impossible to suggest what to do. If anything actually needs to be done.

So, if you want some actual assistance, the next move is all on you.
 


As we have zero knowledge of what the actual problem is, how do you know that will help?
