I formated my computer and add in a new 500gb Harddrive and changed powersupply to a new one (same brand and same model). after installation I try out stuff like surfing webs and play games.. it has a lag spike that goes really really slow for like 5 sec and then back to normal and repeat after a 2 min or 3. I checked task manager and those program i open uses alot-all of my cpu speed, especially on games such as ffxi and starcraft. The CPU usage goes from a regular amount of a few % to 50%+ and sometimes 90%+. I had all drivers up-to-date. at first I thought it was the new harddrive so i took it out and use the old 300gb harddrive again. i install windows xp pro and update all drivers and the lag spike stays. I switch back to 500gb harddrive and format+ install everything again and still the same. i tried everything i know and i can't seem to fix the lag problem. plz help.
