I've had my Athlon 64 3000+ for a week now and have started noticing problems with Windows XP Pro (SP2).
See my sig for full system spec.
I did a fresh install of XP when I installed the hardware and had no problems during install etc.
But now I've noticed, even when pc is idle, explorer.exe hogs the cpu (99%) and memory usage shoots to 200mb. I have to kill the process and then rerun explorer.exe to get the system back to normal.
Is there anything that could be causing this?
When this is happening I don't have any programs running.
All of my drives have been defragged and anti-virus is up-to-date.
I've got all of the latest drivers for motherboard, cpu etc.
Would I be better to get windows xp 64-bit?
PS. Cpu temp is normally around 29 - 33 centigrade when idle and hasn't gone over 40 even under load, so it cant be a problem without overheating etc.
