Premiere Elements freezing

I recently bought a new computer, specifically because my 4 year old computer could not seem to  handle Premiere elements. I bought the following, because I read that this type of processor was good for editing.

Processor            Intel(R) Core(TM) i9-14900   2.00 GHz

Installed RAM    32.0 GB (31.7 GB usable)

Device ID             C1629DE7-3753-460B-9D40-B5728DC66286

Product ID           00355-62028-64480-AAOEM

System type       64-bit operating system, x64-based processor

Pen and touch   No pen or touch input is available for this display

NVIDIA GeForce RTX 4060Ti

However, I'm still finding that after filling up about 5-6 tracks with audio and video, I start to get considerable freezing. I press play, but either nothing happens, I get only audio with the timeline bar not moving, or sometimes I just don't get audio.  It seems to work better if I haven't made any changes over the pasdt s everal minutes, but even then, it often doesn't work when I click on the Play button

I'm starting to think that perhaps it was not my previous processor at fault, but that Permiere Elements is made for editing home videos with 1 or 2 tracks, but not more involved ones. Or perhaps, and hopefully, I don't have my settings optimized.

Any thoughts?

Thank you.
