Bluescreen usually means hardware problems.
Is your video M2T, MP4 or MOV format?
Is your Windows 7 32-bit or 64-bit? Have you ensured you have the latest version of Quicktime, per the program's requirements?
The program should have no problem editing this video. I agree with Ann. Something may be unstable on your machine. Have you manually gone to Windows Update and ensured you have all of the updates, including the non-critical updates that don't install automatically? When did you last run Disk Cleanup and Disk Defragmenter?
Thanks for your hints, Steve!
Sorry for not answering soon, I lost the link, an I was a little bit frustrated...
I found a temporary workaround to avoid the bluescreens, just to finish my project. I conversed my 4K stuff into HD1080, clip by clip. So I could edit with PE... Not really a solution, but it worked :-)
My 4K videos are MP4, XAVC-S. My PC components: Win7, 64 Bit, 6 core, 8GB Ram. Updates for Windows and Quicktime installed, Disk cleanup + Disk Defragmenter run - not quite periodically, but often or when I see problems.
In the last 4 days I encountered another sort of bluescreen: 0x00000124 when rendering + exporting a long video (1h) for test. Today I think I found a solution: CPU temperature was too high, more than 138 degr. Fahrenheit.
Perhaps this could be the reason for breakdowns with my 4K videos? Althoug the error code had been different?
I will try again and report to you, Promised :-) !!
Thank you, Ann!
Probably you are right, - see my answer to Steve below ....
