Hi, I have been having problems lately with my computer...
My computer occasionally lags up and acts really jittery. This is seen
especially when watching videos, playing games and moving the mouse cursor.
Also, my CPU Usage goes up to 25-30% without any applications running! This
happens completely randomly and not when I open a particular program or do a
particular thing.
I have run various virus, spyware and rootkit scanners and all turned up
nothing but a few cookies which I deleted. I have tried Disk Cleanup and a
De-frag and both havent helped.
Can anyone shed any light???
Thanks
Bear in mind that lots of applications running in the background, specially
Av want to update, windows Bits updates engine, third-party apps looking to
connect to the updates server to get updates or check for new updates, can
cause a slow to your machine if not all been managed or scheduled to not run
in the same time!.
About the 25%-30% i think it may be normal as your NIC may connecting to
your ISP to renew the IP address so you see a spike ( a quick one, not ever
lasting one) an evidence on the Sync with ISP to get IP address or to say I'm
a live for a sec or two.
