    Computer will not respond to any command and will not recognise any disc. i can switch on, get the message and switch off and that is all. Only purchased the computer at the end of August.

This may help. If you can't identify the file or program, then use MSConfg. Go to Start > Search. Type MSConfig. Go to the startup tab and disable as many items as possible. Not to worry, the apps are still there and critical items will load anyways. Plus this will make you pc load and run faster.

File header checksum does not match computed one. ???

You have one or more critical corrupted file/s which prevents the laptop from booting up.
To get the laptop operating again, you need to insert the Windows Vista CD and do a Repair and if this fails you need to install Vista again.
