or updated virus scan software or firewall? In re-installing your settings for these could change and it may be doing initial startup scans. Sort the processes by mem usage and watch it just after logon.
Also look at what you have for virtual disk as opposed to what you may have had before.
When I've experienced this (far too often), it was usually virus scanning, firewall settings that changed or were set to default at install.
Hope someone can throw some light on an issue I have got.
MOBO - Asrock Dual Series 4Core Dual-Sata 2
CPU - Intel Dual Core 1.8Ghz
RAM - DDR2 2Gb
Graphics - Nvidia GeForce 7300 SE (pcie)
HDD - 200Gb Maxtor
Just rebuilt this system after the previous MOBO died on me, so I thought I would update some items.
Fresh install of XP Home, updates (windows and drivers) done,programs added back on etc and everything running fine.
A couple of days ago, the pc was taking a very long time to boot, with the HDD LED permanently lit, not flickering but staying on. Once the system gets to the Windows log on screeen and I click on the user name, the log on sound is all garbled and struggles, check CPU usage and it is way high.
I have checked what loads at start up, and there are very few items. Chked with both adaware and spybot, but no problems found.
Cleaned and reapplied thermal paste between CPU and cooler, and checked temp of CPU (30c/86f)
Running processes are 36, which isn't excessively high.
Any ideas what else I can check
