Hey, I just installed a new motherboard and upgraded to 2GB of RAM from 512MB. Any Way, I had to do a clean install of Windows XP and my computer seems to be really sluggish, and CPU Usage is very high or will go up to 100% and then dip to 5% rapidly. Any tips on how to get rid of this problem, i have nothing installed on the computer, thats why it seems really weird. Thanks for your help!
