Hi I have windows 7 professional, System recovery is unable to fix my corrupt registry problem, I have re-installed the OS several times now and I keep on having the same problem. After a fresh install of windows 7 which last a day or so before It stuffs up, it freezes then I get a blue screen "you computer shut down to prevent damage", during the boot up it deletes files which makes Windows unable to boot. If I shut it down it wont be able to boot windows again I get the message your computer was unable to boot then leads me to the system recovery window. What needs to be done to fix this problem, I am NOT keen on installing Windows everyday.

This is most likely due to defective hardware. Check your hard disk with its manufacturer's diagnostic utility. Also, test your system RAM with Memtest http://www.memtest.org/.
