One day my computer blue screened, this was for a known reason but then it would say "Cannot boot from cd" so I screwed with the BIOs and got a bluescreen everytime windows finished, then I tried to load defaults and now it will show a "Gateway" sign and my keyboard and mouse shuts off I've tried reseting my battery this did not work

I know this sounds like it is complicated to me atleast but I cannot talk to my dad whom is a tech wiz for quite some time I need help because it is very hard to play any games (Which I mainly use computers for) on the computer I am currently typing this on

"One day my computer blue screened, this was for a known reason"...

What was this "known'" reason?

"Cannot boot from CD"...

You may have a bad hard drive. Try resetting the bios to the DEFAULT settings. You will find this option at the bottom of the opening bios page
