Vista 32 problems

Hello,
alright I have a problem I have vista 32 bit and yes I know it is old, but yeah still works. The problem that I am having is this, when I turn on the computer it starts just fine and goes strait into the mode as if I pressed F8, which I did not, it does it on its own, then the countdown starts and I for some reason have no keyboard. I cannot use the arrows to choose safe mode or just hit enter to start windows normally. After the computer reaches the final count down it goes to the boot up were it shows the little bar on the lower part of the screen that has that moving deal going through it and then the screen goes black and then will turn blue and has a few numbers and says something at the top left hand of the screen, but it goes to fast to know what it says. then restarts and does the same process over. does any one no as to why this does this.
