I've had Adobe Premiere for maybe a year or two now. I previously had an older system (i7 6700k processor, 32GB memory), when it worked it was working great, but it finally died on me. So, I built a new system with decent stuff:
i7 11700kf with a 360mm liquid cooler
64GB DDR4 (I purchased128GB but decided eventually to only use 64)
1TB m.2 drive for my operating system and files that is capable of up to 7000mb/s speed
1TB m.2 drive just for a scratch disk capable of 3600mb/s speed
.. only thing old in this system is an AMD RX 480 8GB video card.
So, anyway, everything has been running fine for weeks now. Brand new Windows 10 install.
I did a quick test after I built the system.. opened one of my old projects and ran the encoder just fine. Seemed quick.
Premiere opens fine, creates a project fine, but when I go to add an mp4 it freezes my whole computer. I can't even press CTRL-ALT-DEL. After maybe 10 or 15 seconds, the second monitor goes black and loses signal. Then after another 10 or 15 seconds the first monitor goes black. Then after about 10 seconds it comes on and says "Adobe had an unexpected error" or something like that and needs to close. Since I had previously pressed CTRL-ALT-DEL that had popped up, so I hit task manager and ended the task. The computer worked fine, except the second monitor will not come back on unless I restart.
I tried it again. This time I did not try CTRL-ALT-DEL. I just let it go.. same set of issues above, except obviously task manager didn't pop up. So, I then did task manager, ended task, and rebooted again.
I obviously have less software installed than I did last time, but I also have some different stuff.. mostly related to motherboard drivers of the new motherboard and to control it's lighting.
