'System' process CPU usage
in [Help and Support]
|
From: highstrike on 6 Jan 2007 08:18 I have a similar problem to the one outlined by 'fatel' 4/1/07. Have downloaded Process Explorer and the problem appears to be associated with a thread USBPORT.SYS+0x5e96. Used Process Explorer to suspend the thread and 'System' CPU usage seems back to usual figure. How can I correct the problem, which I assume is with the USB driver or can I leave the thread suspended or will it start again after a reboot? Haven't encountered any USB problems since suspending.
From: Gerry Cornell on 6 Jan 2007 20:10 What Windows XP CD do you have? Does your CD include the SP2 update or have you downloaded or used the Microsoft SP2 update disk since? -- Hope this helps.

From: highstrike on 7 Jan 2007 06:03 It's a Compq machine, came with their setup disk, I downloaded SP1 & 2. Saw there was a problem with USBPORT.SYS which was addressed in SP2, the date on mine in Win/Sys32/Drivers is Aug 04. Rebooted since last post and thread starts sucking up CPU resources so looks like I'm going to have to kill it after each reboot. "Gerry Cornell" wrote: > What Windows XP CD do you have?

From: Gerry Cornell on 7 Jan 2007 06:26 This may be a possibility. You experience a delay when you transfer data over a USB port and CPU usage increases to 100 percent on a computer that is running Windows XP with Service Pack 2 http://support.microsoft.com/kb/894618/en-us -- Hope this helps.

No, just synchronised MP3 player, Windows Media player used 20-40% CPU and all the rest taken up by SETI having previously killed the thread that seems to be the problem. Checked all my USB devices and they seem to be working fine. At start up the Found New Hardware Wizard runs sometimes claiming to have found something new but does not identify it and can't install any drivers. I have checked device manager and used USBinfo to check but can't see what is causing the problem, everything works!!
