Computer wont Repair or boot properly.

Computer just shut down on me and it wont Boot up or Repair. I have 64-bit and I tried borrowing my friends 32 bit cd to try and do a reinstall but that wont work. I dont have a 64 bit cd, I only have my CD key. After I try and do Windows Repair, it will tell me they coudltn find the problem and the Blue screen of death flashes on my screen then shuts down. Help please.

You cannot use a 32-bit disc to repair a 64-bit version of Windows.

Failing that, go to your computer manufacturer's support site (you haven't said who it is or what your computer specs are) and check what their recovery procedure is, but it'll be something like tap the F10 key on startup.

Try tapping F8 to see if you have the Repair console on Advanced Boot Options.

If so run Startup Repair repeatedly. If this fails try System Restore from tools list, and SFC -SCANNOW Run in Command Prompt at Boot

If not you'll have to burn a 64 bit Repair CD: System Repair Disc - Create

If you have factory preinstalled you may need to run Factory Recovery or REcov Disks, or find a WIn7 installer for your version to clean reinstall with Product Key on COA sticker: Reinstalling Windows 7
