Okay, I hadn't used my desktop for 4 months and coming back to using it I noticed a small problem, every few minutes sound and video (display) stutters.
This happens everywhere, the desktop, browsing the web, playing music, playing videogames, even the startup animation and sound before the login screen stutters at times.
I've got every single driver up to date, I've checked everything I could and uninstalled things I no longer needed installed. I've been watching different things my computer does when it happens and there's no changes in CPU load, RAM usage, swap usage, neither of my drives are accessed any different, net upload/download is the same.
I've poked around my computer enough to know it's an obscure problem, and probably has some obscure fix. That's the reason I'm posting to Overclock.net in hopes that someone has heard of and knows a fix to a similar problem.
Windows 7 Home Premium 64-bit
AMD Athlon 64 X2 6000+ 3.0GHz
NVidia GeForce GTX 460 (Downgraded to PCIe x16 1.0 by motherboard)
3GB RAM (Forgot exact specs, haven't touched it since I ran Vista 32-bit)
Seagate Barracuda 7200RPM SATA as the main drive
Seagate Barracuda 7200RPM IDE as the swap drive
Chipset is nForce 570-SLI for AMD
Integrated Realtek audio (unsure of the exact chip)
I'm unsure of my PSU but I know it's high enough to provide for my system.
If anyone knows what might be happening please post what you know.
