I recently moved from CS3 to CS6 and now whenever I open a document and select the marquee tool or any other tool photoshop crashes straight away saying Adobe Photoshop CS6 has stopped working. This is Happening in both the 32 bit & 64 bit versions on my system.

Oh I have figured it out, CS6 Doesn't like the use of dual monitors across multiple graphics cards as I have an extra monitor on my intergrated card, I switched this off and away I went.
It's not Photoshop - you were crashing in your ATI video card driver.
Also, you failed to install the 13.0.1 update.
