WinXP Pro and svchosts processor usage issues

[Magum]

Running Windows XP Service Pack 1 SVCHOST goes haywire on my machine taking up 90+ % of CPU usage after the machine has been in normal use for a while. Rebooting fixes the issue, but after a few minutes of just sitting SVCHOST starts hogging CPU cycles. This is on a recently formatted machine (done so twice) with the only change being a new Giga-Byte GA-8IHXP. Nothing is running in the background that could cause this issue, I used msconfig to selectively remove anything from start in registry that could cause this. Is anyone aware of some driver for the Giga-Byte GA-8IHXP causing issues such as this? Any ideas would help. Thanks

Giga-Byte GA-8IHXP

It might not be system specific but rather the software. Happening to me too. Did you just previously run Winamp? Because on my system, I used Task Manager to terminate the svchost that was eating up the cycles, and I find that Winamp can no longer output sound. And it happens that I can create the svchost processor usage by running Winamp for a while and closing it...

You may want to go through and make sure you don't have a bunch of services running that don't need to be run. This might help also: What is the Svchost.exe process(es) in Windows XP?
