I am using Premiere Pro 4.2.1. It was working ok until one day recently it started to run ultra slow. Playing back a standard definition AVI file on the Timeline is impossible. Probably moves about 2 frames per second. I'm not sure if it is a hardware issue but it was working fine, ie. I did not do anything to change the set up of the computer.
Here's the spec:
Custiom built computer:
INTEL CORE 2 DUO E6300 2.80ghz
ASUS P5QPL-VM EPU Mobo
Sapphire ATI Radeon 4600 Graphics - 512mb DDR-3
1 x 500mb HDD (for OS)
1 x Samsung 1TB HDD (for Video files)
Corsair XMS2 4GB (2x2GB) DDR2 PC2-6400C5 800MHz Dual Channel Memory
Windows 7 Ultimate 64 Bit version
Graphics card has been updated to latest drivers. The card has VGA out and HDMI out. Was working fine using HDMI out to Hitachi HD TV for previews but for some reason has decided to run slow now. No obvious reason for it.
While you may not have installed anything new of course there are so many automatic update programs that of course that could be a problem. How many processes do you have running when you open Task Manager in the Processes Tab after you check show all? This would be before you start any programs after a fresh boot. With your dual core CPU and only 4 GB of RAM you really need every CPU cycle and all the RAM that you can muster up.
There are normally 15 processes running at start up. I've even tried closing most of them down, especially disabling anti-virus. This does make a difference to the general running of the computer but minimal difference to Premiere. The issue is with running a separate monitor for previews ie. Preview Monitor - Playback Settings - External Device. Iused to be able to select teh Hitachi HD TV via the HDMI output from the ATI Radeon card. Used to work ok, but now doesn't.
In terms of codecs how can I find this out? I'm using Windows 7.

That is (almost) impossible. Both Bill and I pride ourselves that we know a bit about tuning, but we can not realistically get below 30-40 processes.
Check with Process Explorer and post a screenshot of all your processes.
