Hi, I've just spent the last two days searching through the fourms to try and get an answer for this but couldn't find anything quite the same as this problem. After installing FS9 onto my parents new PC, everything was fine, however, after the PC was restarted, I got a regular stutter every 1-2 seconds. So, I updated the drivers to the forceware 61.12s and everything went back to running nice and smooth. That is until the PC was restarted again and the stutters were back! This time I tried deleting the FS9.cfg and when FS was started, no stutters. Now when I started FS this morning, guess what!! the stutters are back.System specs are:Asus A7N8X-VM moboAMD XP3000+1024MB PC2700 DDR 333MHZ160GB Hard drive256mb GForce FX5700LEIf anyone has any suggestions i'd be most grateful!:-zhelpThanks in advance.TomAFG.

Are there any other USB devices attached to the PC? Reason I ask this, is I had exactly the same symptoms as your getting and it was due to having a USB Force Feedback steering wheel attached.If you do have other USB devices attached, you might want to take a look at removing them all and seeing if it cures anything.Hope this is of some helpRgdsAidihttp://www.avsim.com/pages/0100/avsim_sig.jpg

Hi Tom,Knee jerk - Sound acceleration? I only mention it because on my system, setting it any higher than basic causes major stutter problems.Cheers,

Hi guys, Aidi, I do have a MS Sidwinder joystick, mouse and printer attached via USB ports. I'll try unpluging them. John, I've been through the sound settings in dxdiag but that seems to have no effect at all. Thanks for the feedback, much apprciated!TomAFG.

I once had a regular stuttering problem (like a hic-up) that was caused by an Iomega-drive on the printer-port.When I turned off this device, the stuttering was gone.Walter

Other thing to look at aside from the great advice you already have--is the keyboard one of those "enhanced types" that offers a volume control, email buttons, etc? I have a keyboard like that, and I found early on its driver program caused a stutter in many apps. It is possible when you go through an update process, something is terminating a background app that's getting restarted whenever you reboot.Also, you can't rule out spyware. The latest breed I've seen has been able to get around tools like Adaware and Spybot. I've switched to manually looking at my system via "Hijack This". From time to time I get PC's by my staff dropped at my desk--they ask me to take a look at 'em to see what ails 'em. I do it in exchange for cookies, lunches, etc... Very nice way to moonlight. I digress--the PC's I'm seeing are loaded with spyware. And some spyware I see tries to "hide"--it terminates itself when it detects an unknown program, and then comes right on back when the person reboots. That's why Hijack This has been so helpful as of late...-JohnP.S.--And if my advice works, I'd love to test out that PC-12 of yours :)

Tom:Also check for antivirus software. Some cause stutters, and even worse, cannot actually be turned off, even though you close out the program.Do a search in this forum for "antivirus". Ken Salter made a recommendation a few weeks ago of using AVAST. I switched from Macafee to the free AVAST version.Wilson

AVG is another good FREE alternative also!Happy Simming!Scott :-)
