I have had a problem with Hardware Interrupts using a large portion of my CPU usage. I noticed it about a year ago.
It has gotten worse and worse to the point now where my system just crawls when trying to perform any task. I have not installed anything new in a year and have always had an ext. hdd, a p/s 2 port wireless mouse/keyboard and a USB wireless mouse/keyboard
XP Home ed (SP2)
Pentium(R)D CPU 2.66GHz
1GB of RAM
Any other info needed just ask
Okay thanks for the info on the bootloader rand_79.
So by fresh install you mean format and reinstall windows without the Ext HDD or just install another windows without the Ext HDD?
Ill try to be more descriptive and if theres any specific info you need to know just tell me.
Like I said the interrupts started to appear about a year back when I would do pretty much anything, from open/max/min/close windows explorer or internet explorer to copying and pasting, to watching a movie.
Once the program has done what I ask it the interrupts settle down until the next command I give. I dont know what is interrupting what all I can see is "hardware interrupts" using most of my CPU usage in Process Explorer.
I'm not sure if this could have anything to do with it but the RAM on my computer died a couple months ago (July 09) and when I replaced them with 2, One Gigabyte sticks it only reads as One Gig total RAM. They are within my Mother boards specs.
