Now it seems the problem is slightly different from what I had thought it was.
I have a home built pc with an Asus P5Q-E motherboard, E4600 cpu, 4g's ram and a WD 640g hard drive. The HD is brand new as of 1 week ago.
I formatted all partitions to NTFS.
Partitions are C-49g, E-244g and F-303g.
I've separated the software programs from system software. I had not done this before, but it has no bearing on my problem.
OS is XP Pro w/SP3 and all updates and patches that were needed have been installed.
Had a problem initially with installing updates but fixed the installer with a method found on the MS Help and Support site.
My hard drive is thrashing around constantly. The HD light is blinking around 1 per second during idle times.
When at idle Task manager shows 99% cpu idling.
No activity shows up anywhere including I/O read and writes.
I already turned off Indexing Service.
I tweaked according to the suggestiosn at Blackviper's site and also used Harden-it for a bit more security.
Nothing I have done has helped with the thrashing.
I'm a novice and really don't have a clue of how to fix this.
Last time I posted, it was just for the light. However, I may not have realised that the drive was constantly spinning.
I Googled this for a while and have found that this is not specific to my hardware. Seems to be an XP problem.
Today I tried disabling the Page file app..
No luck. It just made the system slower and I enabled it again.
When I had this problen in the past, I just realised, on an old emachines pc, it presented itself as a constant little flash or blinking on the monitor. Gave me quite a headache. It was most noticeable when Task Manager was open. When I highlighted a process I could see the blinking.
I can do that now too.
I know it's something within XP but it's way over my head.
Hope you can help.
