I upgraded my computer from 16GB to 32GB of RAM about two years ago, expecting Photoshop to load faster, handle large files more smoothly, and let me run multiple applications at once. Instead, performance has become worse. Even moderately demanding actions can take around five seconds, and the computer sometimes crashes, briefly shows a black screen, or displays broken window frames before recovering several seconds later.
Event Viewer suggests that the pagefile is filling up. I understand that Windows may still use a pagefile even with plenty of physical RAM, but I'm confused about why it is filling so quickly when I only have a few programs open. The pagefile is already set to be managed automatically. Photoshop is also a major part of my workflow, so switching operating systems or replacing it is not realistic right now.
What should I check to find out whether this is a RAM configuration issue, a Photoshop setting, or something else?

Check Photoshop under Edit > Preferences > Performance and raise Memory Usage to roughly 70–85% of the available RAM, but don’t set it to 100%. Restart Photoshop afterward. Also check Task Manager after closing Adobe applications; sometimes an Adobe process remains running and continues consuming memory. If Photoshop still causes crashes, test the RAM with a memory diagnostic and update or reinstall the graphics driver, since black screens and corrupted window frames can also point to GPU or driver problems.
The pagefile is normal and does not mean Windows has run out of physical RAM. Applications can reserve more memory than they actively use, and Windows may move less-used data there to keep memory available. Leave virtual memory set to automatic rather than forcing a small fixed size, and make sure the drive containing it has plenty of free space and is healthy. A nearly full or slow drive can make paging feel extremely sluggish.
The pagefile is already automatic, and changing it to a fixed size didn’t improve anything. Buying another drive isn’t practical for me right now, so I’m trying to determine whether the issue is caused by Photoshop or the memory configuration.
First, verify that the memory is actually running at its rated speed. Check the BIOS and make sure the correct XMP or DOCP profile is enabled. Also confirm that Windows recognizes the full 32GB and that very little is listed as hardware-reserved. If the RAM speed and capacity look correct, check Photoshop’s own memory settings and other application configuration.
I haven’t tried disabling and re-enabling XMP yet. It was enabled when my motherboard was replaced. Windows shows about 11.3GB in use, 19.2GB committed out of 38.9GB, and only 79.5MB as hardware-reserved.

Increasing Photoshop’s memory allocation may help, but the black screens and damaged-looking window frames suggest checking the graphics driver and GPU acceleration too. The pagefile itself is probably not the root cause unless the system drive is full or failing.
