100% CPU Usage
Hi,
I am new here, but i was referred to here by a friend.
My problem is as suggested by my title that something is causing 100% CPU use. At first I checked Task Manager to find that my CPU use was on 100% but by 'System Idle.' (I realised this should display as using about 100% Use when the PC is idle, however this is at 100% and my CPU Use is also at 100%)
I downloaded and used Process Explorer which informed me that the 'Interrupts' and 'DPCs' process, which are sub processes of System Idle apprantly, are sharing my full CPU capacity at about 40%:60% respectivly.
After alot of time playign with various things.
One-by-one eding processes, didnt help.
msconfig startup on basic processes- fixed it
allowing one more process per startup at a time helped me track it to Wireless Zero Config. When this process is disabled i never get the problem.
With it enabled:
PC starts up, connects to wireless network everything is fine for what appears to be a random amount of time. The suddenly CPU use shoots up to 100%. If i disable the wireless connection (rather than WZC) everything drops to normal. On re-enabling the connection it usually doesnt shoot up for a bit. 10-90 mins. Sometimes it rises instantly.
Does anyone have any idea what this could be?
My system is
AMD Athlon 64 3400+
Windows XP Pro Corp with SP2 installed
K Corp KLG-350 Wireless Card
ANymore information needed just ask.
Thanks Guys and hopefully someone can shed some light on this for me.

There is a driver listed at their site which is marked as being newer than the one included in the box. It might be worth a try.
Another thing I'd recommend is checking your router settings and makes sure everything there looks good - especially your security settings.
Finally, it would be a good idea to post a HijackThis log here. If you have a virus, trojan, etc, doing something behind your back that would account for the 100% CPU usage.
Good luck.

Given that you have some unknown process running your CPU usage up to 100%, I would recommend that you start a new thread in our Spyware/Virus/Trojan Discussion Forum, then let the experts there make sure that there isn't some mischief going on behind your back.
