Unable to Boot in Safe Mode

ok, the thing is i had this virus on my pc which i learned after a lot of research required me to boot in safe mode in order to remove it. The problem is, while trying to boot in safe mode several times, my computer just crashes to a blue screen. I then learned that besides pressing F8 there was another way to boot in safe mode by going to "Run" and typing msconfig and booting it manually that way. Unfortunetly, this technique ended in the same crash. By now i realize that it is IMPOSSIBLE for me to boot in safe mode. My one major problem now is, that i CANNOT BOOT IN NORMAL MODE EITHER. I guess by trying to boot in safe mode using msconfig, i've changed my pc's settings to where now, normal mode=safe mode, and obviously, safe mode keeps crashing. As of now i cannot boot my pc AT ALL. I thought there might be a way to recover/fix safe mode by using the windows cd, but i really dont know what to do. i hope you guys can help me out, thanx
