How do I, someone scarred to do anything with my computer, start my computer up on safe mode?

I have been getting different things come up on my computer: Program:C:\ProgramFiles\DISC\DISCover.exe, this comes up when I start my computer, Yahoo Browser Update that states I need an anti-virus put in my computer and starts running a fake scan. I am not good with my computer but need to keep it going till I get a new one. Can someone help me with this?

Thanks
