Unfortunately, this is by far not enough information to give you a hint. It may be your system is way underpowered for the material you are trying to edit. There could be a multitude of processes running, there may be a virus, a heavily polluted system, weird codecs, and the like.
Have a look at this: If you need help quickly...Guideline for posting an effective question
and start with the basics, like OS, hardware, software version, source material and codecs used.
I should have been more detailed in my previous description. I have an Athlon 3800+ processor, GeForce 7600GT video card, 7.5gb RAM and 1.9TB raid 0 Seagate hard drives. I've attached the DxDiag file for additional reference. I have the processes down to the minimum necessary to run the pc and the video is just DV captures with Digital Juice swipes and background.

Thanks for posting the file and the additional info.
A couple of questions if I may.
You say you have 7.5 GB RAM. This is a rather odd figure and your DXDIAG indicates 4 GB installed.
I sincerely hope you DO NOT HAVE 4 PARTITIONS on your MAXTOR disk, using C, D, E and F.
What are the nVidia striped disks H and I for? Same with J and K? Are these not properly configured as a stripe or were these meant to be JBOD's?
Your video drivers are up to date, but does the same apply to your DirectX software? Check on the Microsoft site whether you have the latest (03/09) version. While you are checking this, also check the INF file for the nVidia chipset, there may be a more current one.
Normal DV material should normally not be a problem for previewing. Can you post a screenshot from Process Explorer?
Whoops. I obviously fat fingered the ram description. I meant to list it as 3.5gb ram. The other .5gb is used by windows. The raid drive contains four logical partitions. The first two are used for the windows swap file and for the multimedia swap file. Another partition is for the storage of all of the digital juice files and the bulk of the space is used for all of my multimedia files including the video projects. Windows is on drive C (obviously) which is not on a raid drive.
I'll check the DirectX in the morning. It is frustrating since with Premiere Pro 1.5, the system ran much, much better.
Lastly, there is one more issue that may be playing a part in this equation. Every time I launch the program, it crashes after I choose the project to open. I've done a lot of searching for a solution. I've removed most of my fonts, updated the video drivers and found the shift key "fix" on Adobe's support site. So if I hold down the shift key during the launch until the welcome screen appears, the program will not crash. This is extremely frustrating in and of itself. I just can't tell what's really going on here.
First step: Remove all partitions. Only use one partition per physical disk.
Second step: Check your raid setup. Is it raid0 or JBOD?
Third step: Post a screenshot from Process Explorer.
The hardware requirements increase with each version, so what worked with 1.51 may be taxed with CS4. I believe they call this 'progress'.
Read this article why you should NOT partition drives at all: http://forums.adobe.com/thread/427772?tstart=0
Like your style bow tie daddy and thought you may be able to help where adobe techs have failed since 12/08.
To begin Premiers CS 4 12/08 release.
Problem: can not playback HD in either 720I or 1080i with out shuttering. This makes it difficult to edit in a proper work flow especially when voice sync is required. 720I is a little better but unworkable, 1080i does not even shutter just freeze frames. Can output to blue ray disk a plays perfect but hard to edit.

Have done all adobe updates, no improvement.

Can moving from a disk based drive to a solid state help?
Thinking of OCZ 200mb/s read.
Does the average data rate of each file have anything to do with this and are they cumulative along the time line?
SD 3.8 and plays fine
720 2.4 problems
1080 4.9 problems
When you play back is Premier reading and writing at the same time?
Is it reading the master file while writing to the tmp in roaming?
