Windows will not load and crashes on startup repair

[Elletee]

Hello i would appreciate all the help i can get. I have an acer aspire 5742 laptop. I was running windows 7. I do not have a disc as it was already loaded onto laptop that was a gift. Machine was running ok, it would overheat from time to time as i think the battery was on its way out, anyway thats not the problem. 2 days ago it switched itself off, when i tried to reboot i got a screen saying windows failed to start with options to -launch startup repair or - start windows normally.
when i choose start startup repair it says in grey at bottom of screen loading windows files then it goes to a black screen and freezes.
If i choose start windows normally it says starting windows and logo appears, then it just crashes. Please help me.

What is on the crash screen?
Boot into advanced boot options http://www.sevenforums.com/tutorials/666-advanced-boot-options.html
and select :

Disable Automatic Restart on System Failure​

Prevents Windows 7 from automatically restarting if an error causes Windows 7 to fail. Choose this option only if Windows 7 is stuck in a loop where Windows 7 fails, attempts to restart, and fails again repeatedly.

Now crash information stays on your screen.

Overheating is not a good thing! Can be caused by dust or thermal paste on cpu not fitted nicely anymore. Don't put laptop on a blanket so ventilation is fine. It isn't too hot now?

windows recovery environment should boot in case of problems (normally). Unless:

• faulty memory
• faulty harddisk
• faulty mainboard
• virus
• etc

first test your harddisk. Then memory. Do you have a win7 system repair disc (64 bits)? Do you have a win7 install dvd (64bits)? You can create a system repair disc on another win7 machine.
