SORRY IF I HAVE POSTED THIS IN THE WRONG AREA, BUT IF I HAVE, PLEASE MOVE IT AND DO NOT DELETE IT. THIS IS A SERIOUS PROBLEM I CANNOT SEEM TO SOLVE. Ok, I've been all over the place trying to describe my problem to people, and getting a "I don't know what's wrong!?" type of response. Now, before I describe to you my issue here, let me just say that I'm not the least bit computer illiterate. However, this issue has overwhelmed me and I have tried everything to get rid of it, so I'm hoping you guys can help me out. ^_^; SPECS: AMD Athlon 64 3200+ 2.2ghz ASRock K8UPgrade Mobo (4x/8x AGP | 2gb Max) Realtek AC'97 7.1 16-bit On-Board Sound 30GB Quantum Fireball 1GB (2x 512) PC3200 RAM 64MB Xtasy nVidia GeForce4 420mx (4x/8x AGP) (512MB nVidia Arrives Tomorrow.) Running Windows XP Pro (SP2) 480watt Blue LED, Chrome "Demon 480" Power Supply The Damn Issue: Whenever I start up ANY game with the exception of Unreal 1 (I love classics) - The game will run fine like it should for about 20-40 seconds, and then it will begin to stutter as if I were running the game on a 220mhz Pentium MX Pro. Its not a fast-pace stutter either, its like "Move 5fps every two seconds" type of deal. Unreal Tournament 2004 seems to do it after being on the title screen for about 5 seconds or so, while UT:GOTY and others take the 20-40 seconds before it happens. I have also noticed that I have six SVCHost processes running at once, but a lot of people have told me thats normal, but it was not like that before. Anyway, here is what I have done to try and fix it, to no avail: -Defragged PC Completely -Ran Norton Antivirus 2005 -Tried Different Cards: PNY Geforce2 (4x AGP), 3DFX Voodoo4 4500 (PCI) -Reinstalled the games -Updated to Service Pack 2 -Upgraded BIOS -Checked for Driver Conflicts -Opened My Machine and tested memory, and other memory. -Ran Diagnostics on my Harddrive -Freed Up Space (I have 14 gb free) -Tried switching Power Profiles in Device Manager -Ran Fully Updated Ad-Aware -Ran Fully Updated Spybot -PC was initially up to date on blockage with SpywareBlaster -Disabled Norton Antivirus/Internet Security 2005 -Fully Updated All Video Drivers. So being defeated and after trying all I can posibly think of, searching through the web, and so on so forth, I end up here. Can anyone help me? This problem is seriously screwed up. (Also note, that I only scan for Spyware every six months, and rarely turn up with any at all, so I keep it pretty secure.) - I've also heard of other problems between XP Pro and the Athlon 64 series processor, but I couldn't find in-depth information on that. Thanx, to any who at least try. EDIT: Also, I should note that these were games that would run extremely smooth without so much as even a twitch of lag offline. This problem just started recently.
