Hi folks,

I have an intermittent problem on my computer which is extremely annoying. Once or twice a day my computer will start "pausing" for a couple of seconds at a time as I move the mouse across the desktop. This also happens inside some games. Sometimes optimizing the memory with TweakXP will stop the pauses; sometimes it won't. This happens when there are no applications running as well.

Usually, the System Idle Process is the only thing showing CPU usage (99 percent).

My system is as follows:

Pentium IV 2.661 gHz Socket 478 processor
Aopen AX4T II Motherboard (online sound and modem disabled in BIOS)
512 mb of Samsung RDRAM
Soundblaster Audigy II
Radeon 9700 Pro video card
Sony 40X/16X DVD-ROM drive
Sony CRX140E CDRW
WD 80 gig hard drive (ATA100)
Logitech Mouseman Marble
Linksys LNE100TX NIC
Linksys Wireless Access Point router (using cables, not wireless)

It is very annoying when the system starts doing this, and I usually have to reboot to make it stop. This happened before I put the Radeon or the Audigy in my system (I reformatted before those installs too) so I suspect they are not the problem.

I am running Windows XP Professional.

Anyone have a suggestion?

Thanks,
John
