My computer has this ''your computer was unable to start'' error, I tried to reboot it in safe mode but it doesn't work...

uh oh is it a dell

No, its a Toshiba

You may have to start with the installation disk to make repairs. Sounds like a kernel corruption. Of course I entered a state of arrested development at XP. I am an Apple guy now.

Used to be the good thing about reinstalling the basic part of XP wouldn’t mess with any customizations or settings you have done. Hope that hasn’t changed.

u need spywear or somthing. my comp keeps poopin out on me, virouses. idk i got a guy who fixes it.

Sounds viral to me. Have you have windows pop up on you from (supposedly) adobe or windows security? And then click on one of those links?

I would try asking here. This is obviously going nowhere fast.
