Lightroom 5.3: On Windows 10 severe lags and "Not Responding" during development

I am running into remarkably debilitating lags while working on photos in Lightroom 5.3. I am also running Windows 10 on a Lenovo featuring an Intel Core i3. I've read through the other forums, and haven't yet seen my exact issue. Many people describe full crashes and entirely non-responsive performance for eternities. My problem, however, is simply (yet excruciatingly) lag. When I move a slider or select a tool. Lightroom won't respond for anywhere from 20-50 seconds, neither in previews or otherwise. Often, I cannot click anything else until that rendering completes. Rarely, the program lists itself as "Not Responding" until it fixes itself a minute later, when I will click again, and wait for another minute. It is literally taking almost 30 times as long to process one photo (where a five minute fixer becomes a two hour ordeal).

I love Lightroom, and I enjoy my work there, but this is making it hellish. I have increased the RAW cache, have plenty of memory and RAM, removed unneeded back-up's, and have no issues with any other programs on my computer. I also attempted to deactivate the GPU accelerator, but cannot find the option in Lightroom 5.3, and when I attempt to manually disable it, I cannot seem to navigate Windows 10 successfully.

Please, please let me know what I can do to rectify this hang-up. I'd really love to return to work.

Thank you so much!

Can you post your system info here from Lightroom's System Info dialog Help>System Info...?

You should try to update to the more recent Lightroom 5.7, see

Then try to reset Lightroom's user prefs. See on how to do that on Windows.

If this is a recent issue I would try to do a system restore back to the configuration prior to having the issue.
