Whatsapp desktop keeps crashing windows 7
Maybe there are other causes of Lightroom crashing, but so far as can tell, Lightroom is now completely stable on my system and I can get back to using it for its intended purpose instead of wasting more time investigating why it crashed so often. I had even completely rebuilt my system from scratch, reinstalling Windows 7 and doing a completely clean re-install of Lightroom, to try to solve the problem.
Having created the shortcut, I pointed the icon properties to lightroom.exe, and the desktop shortcut looks identical to the old Lightroom shortcut. The "F" in the middle is a hex number, which determines which cores are used you can experiment by varying this to enable or disable specific cores, but for me "F" works well: this enables CPUs 0 to 3 (inclusive) and disables the remaining 4 for Lightroom.
Obviously you may have to adjust the path if you have installed Lightroom to other than the default location. To do this, create a desktop shortcut and set the target to C:\Windows\System32\cmd.exe /C start "lightroom.exe" /affinity F "c:\program files\adobe\adobe lightroom\lightroom.exe" You need the quotation marks as show. After some research, I was able to create a desktop shortcut to launch Lightroom with Affinity set to use the first 4 of the 8 cores. Problem solved, but it was still a bit of a bore having to set the Affinity every time I started Lightroom. As an experiment, I exported 1,600 files in a single batch: it took some time, but Lightroom completed the task without crashing. Since limiting core usage in this way, about a month ago, I have had not a single BSOD and my catalogue optimizes properly. After some experimentation, I determined that using only 4 cores was a good compromise: no noticeable performance hit, and no crashing. Limiting the number of cores used to less than the full 8 available solved the crashing problem. Using task manager, it is possible to set the Affinity of a running application, that is, to determine which cores it uses. This led me to experiment with how Lightroom uses CPU cores. Even though I have more RAM than Lightroom ever seems to need (20 GB installed), using Task manager I noticed that CPU usage was often maxed out for all cores, even though this should not be expected. My system has a 64 bit i7 processor with 8 cores, 2.3 GHz overclocked to 4GHz (the overclocking was not the problem: Lightroom still caused the BSOD with overclocking disabled). Moreover, it was not possible to optimize my catalogue. The second problem was that, even after disabling GPU acceleration, Lightroom still regularly crashed my system. This is a well-known solution, easily found by searching, and I will not add more details here. Disabling "use graphics processor" in Preferences helped (to the extent that allowing Lightroom to run at all may be termed help: it was freezing on launch), which I could only do by manually editing the preferences file, setting autobahn to false. It is well known that enabling this option (and it is enabled by default on every new installation or update) can cause problems.
The first problem I had was the use of the graphics processor. I wanted to share with you the solutions I have found to this: Lightroom was becoming unusable, crashing on attempting to export even a dozen RAW files to JPG. These crashes are complete system crashes, causing my system to freeze and restart (Blue Screen Of Death), not just Lightroom itself crashing. It has, however, been plagued for some considerable time by Lightroom crashing, particularly after numerous edits or on exporting files. My computer is several years old, but should still be good enough to run Lightroom without a problem, even though my catalogue is quite large (about 26 GB). I am running Lightroom CC under Windows 7, 64 bit.
