I was just using my computer(Windows Vista) listening to music (on it) while drawing something up for my class until my mouse and keyboard died luckily my BAMBOO pad was working so I "X" out the open windows and restarted my computer. As I was waiting the screen was black and the Windows Failed to start
showed up…and again my keyboard wasn’t working so the timer was over and it automatically went to repair, when that was done it showed again so I turned off my computer and turned it back on suddenly my keyboard worked and I just hit enter on "start windows automatically" then it just started working.

I looked up how to repair this problem but they all say I need the disc to Windows Vista which I don’t have so my question is How do I repair it now?

I tried turning on my laptop and it takes me to a screen which says "Windows failed to start. A recent hardware or software change might be the cause." It then gives me two options, which are "Launch Startup Repair" and "Start Windows Normally." I have tried using both, but either choice makes my computer restart and takes me to the same screen. Alt+Ctrl+Del restarts my computer as well. Escape shuts of the timer to automatic selection. I have tried running both the recovery CD and the support CD, and neither works because Windows is not operating. Do you have any suggestions as to what I should do?
I cannot give the computer any commands via mouse, and it will not respond to any keyboard commands either.
