Project keeps stuttering during preview.

DVD projects or HDV projects, doesn't matter.

Works for a while, then starts stuttering as if there is a memory or resource leak.

Forces me to quit Vegas and usually re-boot the PC.

Very frustrating. One project working late into the night the darn thing kept locking up. Had to keep re-booting, working on small sections, and then re-boot again.

When this condition has happened, machine is slow even after I have quit Vegas. To clear the condition, I have to re-boot.

Any suggestions?

This doesn't sound like Vegas is causing the problem, my guess is that something is running in the background and eating up CPU resources.

It may not have anything to do with your specific problem, but Windows 7 has been known to just lock up for 30-40 seconds at a time for no apparent reason. Maybe your problem is somehow related. Here is the info with a link to the hotfix:

I see this is your third post.
So mentioning some basics is in order.

Match your Project Properties to your Media. This is a very specific and essential procedure:
1) Open the Project Properties dialog.
2) Click on the "folder"icon in the upper right-hand corner.
3) Using the Explorer, click on the Media File you are using.
4) Click "Apply," then "OK."

Then, in your Preview Window:
1) Select "Preview, Auto"
2) Unselect "Scale to fit Preview."
3) If necessary, Unselect "Simulate device aspect."

Be sure, as suggested above, to disable anything that is eating your CPU resources.

That being said, I have no problem previewing HDV on my lowly entry level dual-core Vista notebook.

If you also have effects on the timeline, Vegas provides prerender options to overcome stutters.

Have Vegas 9.0e 64 bit and Windows 7 Ultimate 64 bit running here as well - and since may 2010.
Editing HDV works very smooth and previews at full speed.

Try to check with Task Manager / Resource Monitor which program is stealing your cpu power.
Had the issue here on a laptop with a newly installed internet security suite which for the first couple of weeks scanned and scanned and scanned the machine for threats and so left little power for other tasks.

Are you running Norton Anti Virus? It's a huge resource hog and known to be a problem for most NLE's.

Apart from the obvious possibility of RAM problems check the following because your problem is familiar.

When Vegas goes bad check under Task Manager that you've really killed the Vegas90.exe process. What seems to happen is when Vegas goes bad it spawns another copy of the process which is probably to handle the error logging. Myabe it never completes or maybe you don't give it enough time.
Either way it can get stuck in RAM and restarting Vegas will result in poor perfromance and another lock up pretty quickly.
If none of that gets you far or as a general tip anyway try reducing the thumbnails to head and tail only. Try reducing Preview RAM to a small value. Don't use 32bit Float and if you're using preview over firewire reduce Sync Offset to 0 frames.

None of the above may relate to your problem, it could be a faulty power supply for all I know but they're all pretty quick to try out.

Oh and check all your drivers are up to date, duh.

Thanks for all the suggestions. Tried them all.

No luck.

Wondering if I need the Cineform program?

I am editing on a 4 GB laptop with a 7200 RPM HD and an Intel T9900 running at 3.07 Ghz.

Switched to an older laptop. Windows 7 Vegas 64 bit, same media files, no problems.

Edits just fine.

No stuttering.

I am suspecting driver problems, memory, or some other hardware related issue.

Final answer appears to be an overheating problem with my Dell e6400 laptop. Numerous consumer complaints to Dell on this issue. Found a program called Throttlestop that may help if it does not burn up my CPU in the process.
