Computer keeps periodically freezing, help me please.

Hey

For the last couple of days my computer has began freezing for approximately 2 seconds every 30 seconds or so. At first I thought it could be a virus or spyware. As i am very security conscious with my computer, have both virus and anti-spyware real time protection and am careful with what sites I go on, i found this to be abit odd. However after many virus/spyware scans (With ad-aware, Avast, AVG, Super-anti-spyware and Spyware terminator) I found not a trace of anything.

I then defragged my HDD (which I do on a frequent basis anyway) which failed to resolve the problem. Ive also completely cleaned my computer with Ccleaner and Advanced windows care V2 and still nothing.

I then ran my task manager and this has shown in the performance tab that my CPU usage hangs around 4% with nothing open and then every 30 seconds flies up to 93% it is during this time that my computer becomes unresponsive for 2-3 seconds and then goes back to normal again.

Do any of you know what my problem could be?

PS. I also pay close attention to my start-up files and all of the ones in there i recognise and are important (such as anti-virus and firewall etc)

Ive just tried that and it hasn't made the slightest bit of difference :'(

Its not getting too hot or anything is it? I'd check your fans and stuff first, and make sure its not a physical problem.kamikaze_pigmy

No it isn't getting too hot, i would know if it was too hot because my fans would be spinning really loudly, i have the side panel of my case removed and its completely in the open so there is also plenty of ventilation.

Ctrl-alt-delete and spot the process that uses your cpu every 30 seconds, then google that process.

Edit: Start/Run/ then type "msconfig" then disable that process
