Vista hb cpu usage spikes then drops to 0%

Am not sure if I'm posting in the correct area, if not please suggest/or reroute my submission to the correct subheading. I've attempted to resolve this cpu usage problem with little/no success. A few months ago I noticed my system freezing, stalling and video streaming and playback would stutter, freeze and or stall with latency issues in abundance. I also noticed Windows Task Manager at start up revealed: Processes = 61, CPU = 0%, Memory= 41% I've vacuumed the system exhaust vent and use a house fan to assist airflow. Though I read many possible solutions, most were a bit more complex than I am comfortable with or were for XP or Windows 7.



Am not a gamer. I've ran numerous a/v, systematic defrag, registry, junk file, etc scans. I don't know how to “shut down” or turn off processes nor reduce the cpu usage which in some cases red line. Any and all assistance is appreciated and gratefully accepted. PS: Am a beginner at this so please go easy on me!

Howdy,

Have you opened task manager and click on Processes tab and see what is taking up the most memory usage?

I would get a free A/V like Microsoft Essentials or Avast and try removing Lavasoft

 

Megabit:
I have opened task manager and have observed multiple items using Memory (Private Working Set). I don't know how to "shut down" or close off these processes w/o making things worse (I'm a novice at this stuff). Besides, were I able to shut down a power hungry system; wouldn't rebooting just "turn it on" again? Concerned about the possiblity of a bug; I've used Super Antivirus, Ad-Aware, Advanced System Care to date on Supera/v has located MUI's, ASC has found Privacy issues. Per your suggestion I removed Lavasoft and will try Avast. Microsoft Security Essentials has caused problems and will not be used again on this current system.

 

I would also uninstall Advanced System Care as all it will do to your computer is make it unusable.
