One program (Lightroom 5.7) hangs and causes my CPU to spike, while other programs that are (supposedly) more CPU intensive doesn't cause my CPU to max out.
Lightroom will sometimes go into a cycle of Not Responding - then the Lightroom window will turn solid white - then it will go back to a normal looking window but Not Responding - then go back to a solid white window - and continue doing this until I can ctrl-q out of it.
If I look at resource manager when Lightroom is doing this, it looks like this:
The real strange thing about this is that WHILE lightroom is doing this, I can still open up other programs (such as Photoshop or a web browser or two) and run them fine (they will be a bit sluggish, but they will be running).
This started about 6 weeks ago and I think it happened after a windows automatic update.
Before that, IT RAN FINE FOR OVER THE LAST 8 MONTHS.
I have run all the Dell Diagnostics and whatever Microsoft diagnostics I can, and they all say my system is fine. I've run Virus scans and chkdsk and chkntfs and they all say my machine is clean.
I've tried asking on various Adobe forums, Lightroom forums, toms hardware, and nobody seems to have a better suggestion than "buy a new computer."
Admittedly, my computer is old (Optiplex 780 SFF Core 2 Duo E8400 with 4GB Ram) and I plan on replacing it, but I hope to replace it LATER rather than sooner.
Thanks in advance.
