Windows 7 continually reboots

First post, so please forgive me if it's in the wrong place.

I ran an executable file like a fool, and now I get the blue screen that says that something has gone wrong and my computers is rebooting to avoid damage to my computer.. It boots through the boot screen with the Windows logo, but as soon as I should see my desktop I get the blue screen again, and my computer reboots again.

Any help would be greatly appreciated.. I think I'm going to find some way to boot from USB or cd, but the complicated part is that I bought my computer online, and it didn't come with a windows disc, just the license sticker on the bottom of the laptop. I do have another computer with a cd burner. One other problem is that of my 4 computers, this is the only one running Windows 7.

Thanks,

Kyle
