I have a computer (well two really) where it randomly freezes for a few (up to 15) seconds when running but then carries on fine. The PC is on a LAN and running a syslog server. I have replaced the motherboard, processor, videocard, mouse, keyboard, hard disc (one PATA, one SATA), floppy drive, power supply, monitor, tried either DIMM on its own, removed all PCI cards, reinstalled Windows XP SP2 twice etc.
The only thing that I haven't changed is that they are using the same RAM (Kingston PC3200 on the motherboard approved list) and that the onbaord ethernet for both boards is a Marvell Yukon chipset. The motherboards are Asus A8V Deluxe and Asus A7N8X-E. The videocards are Matrox and Asus ATI based. I have the latest NIC driver and VIA 4 in1 (and nVidia ones when I was using that board).
Anyone got an idea outside new RAM or NIC?
