Hi all,

Please, please, please can I have your help? I've got this problem which has been bugging me for... Oooh... Ages.

Basically, every 30 seconds (and it is that exact), the PC stutters - if I'm dragging a window about the screen, it stops for about half a second and if I'm playing audio (with WinAmp, MSMP, RA or anything else), it stutters (repeats itself) a few times.

Now, I've slowly ripped everything out of the machine (both SCSI cards, modem, network, CD drives, floppy, swapped hard drive, swapped DDR RAM for SDRAM and reinstalled Windows 2000 pro.) and I've still got the problem.

The motherboard's an Asus A7A266 with an Athlon 1400 on it. The BIOS is at the latest patch level (1009). The only software to run at startup is "MS Active Sync 3.5" and "NAV2002".

Any ideas?

Cheers,

Nicholas.
