I have 4gb ram, core2duo processor and DG31 PR motherboard and my comp is just 4months old.. but my cpu usage is upto 55% when having opened just one window say mycomp and moving it randomly and slowly a couple of cms.. on the desktp.. the window is severly breaking up.. and when tried installing any program for ex: nero7 its taking 100% cpu usage and the speed is also very slow when compared to earlier.. this is the same problem even after formating my hdd twice.. and this problem is with xp sp2 & 3.. while installed vista ram usage is high but cpu usage is slightly low for i.e around 45% and again 100% while any installation.. this i m facing on a fresh installation also where in i havent installed or plugged any thing apart from the mb drivers and nvidia graphics drivers... plz help
Could point to both hardware and software issues..
but first check software issues. can be due to virus/spyware running.. check taskmanger and lists the processes by cpu % ... this will give you the process which is gobbling up the cpu cycles. make note of the file and track it down in hard disk. you will then have to research what it is for.
if you have a antivirus installled it may be possible that it is virus scanning the disc.
hope this helps
