I have a windows workstation
i7 3639K chip
gigabyte X79 MOBO
NIVIDEA Quadro 4000 graphics card
32 GB ram
WD 2TB caviar green harddrive
I know the hard drive is not great but it was the best I could afford at the time. So took computer to the shop for a power supply issue and the helpful tech has updated everything (service pack 1) [Usually I keep this machine offline and do not update when I have everything working- if it isnt broken dont fix it is my philosophy]
Premiere pro usually runs very very fast on this machine - I have been editing film quite happily without needing to render sequences first and have been getting very responsive performance from the timeline scrubber and preview window--- but now there is a long delay between moving the timeline scrubber and the preview window changing and also premiere pro is continually freezing when exporting (no error or anything - it just hangs on x% and does not go any further- when you try to cancel - then it starts "not responding" and eventually you have to crash the program to continue..[At the moment I am trying to edit and export short .png sequences from 3ds max]
I have updated Premiere pro 5.5 and tried to update graphics card to latest driver, but this has not fixed the issue,
1) what should I be doing to try to get Premier Pro back to working how it was?
2) any suggestions (adding an SSD or creating a RAID or changing settings?) to get better performance out of my machine (once I resolve my current issue)
The only idea I have is to reinstall Windows from scratch, update it, then reinstall Adobe software and update that.
And leave it connected so the updates come regularly. (They are there because something is broken, the update fixes it.)
Just as a point of comparison Im am current with Win 7 updates on my HP Z820 and have none of the issues you have mentioned.
Either do what Jim suggests or call Eric at ADK Computing.
