Adobe flash player will not work on my laptop?

Hi, I've downloaded the flash player maybe 20 times, but the Adobe flash player test says the flash player is not installed on my computer.  But when I look in my programs, there it is.  The flash player does not work on either IE or Firefox.  Also, after I download the flash player every time, my CPU stays pegged at 100%.  If I uninstall the flash player, the CPU usage immediately goes down to normal.  I used to have Adobe flash player and it worked just fine.  No, I do not think I have any viruses or malware.  The laptop is a Toshiba A505-S6965 with Windows 7.  Thanks for any help.
