Visual Studio 2013 Express for Web keeps on crashing on start

My visual studio keeps on crashing and I don't have any idea why it does at all. I've already tried restarting, repairing and even reinstalling it but still no luck. I keep on having this error.

Problem signature:

  Problem Signature 01: VWDExpress.exe
  Problem Signature 02: 12.0.31101.0
  Problem Signature 03: 545474d4

Any suggestion would be greatly appreciated. Thank you !
