Photoshop crashes on launch.

Question

I've just downloaded the Photoshop/Lightroom package.  Lightroom seems to be working just fine, but Photoshop crashes for no apparent reason immediately after start up.  I've tried uninstalling/re-installing as recommended, but with no success.  My system is a Dell PC running Windows 7 64-bit.  Simple answers, please - I'm no techie!  Cheers.  Richard

Below is the detail from the 'Event Viewer'.  Since my last post, I've updated my device drivers and BIOS.  No difference.  As I mentioned before, Lightroom works OK, but if, when I have an image on the screen,  I click  'Edit in Photoshop', Photoshop starts, briefly displays the image, then crashes with no error message other than 'Adobe Photoshop CC 2014 has stopped working', followed by 'A problem caused the program to stop working correctly.  Windows will close the program and notify you if a solution is available' Then nothing!
