Windows 7 Pro USBPORT.SYS And ATAPORT.SYS 100% Cpu Utilization
» I install Windows 7 Pro onto my machine, and the install completes, Everything gets really slow and sluggish. I then check taskmgr, and I see that the CPU is at 100% utilization. I ran the performance monitor and found that ATAPORT.SYS and USBPORT.SYS are the main culprits eating up my CPU. Any ideas of workarounds/drivers etc to help solve this issue?
Usbport.sys is a Windows driver file that controls the operation of your computer's USB, Universal Serial Bus, ports. Windows XP comes with a version of usbport.sys that controls both USB 1.1 and USB 2.0 devices. Occasionally, the usbport.sys file becomes corrupt and may cause your computer to crash or may use excess system resources. You can download and install a fresh version of usbport.sys to correct these problems.
Turn on your computer. If your computer crashes upon startup, restart the computer again and instruct your computer to boot into Safe Mode when prompted by the system. > Download an usbport.sys file to replace your corrupt version of the file (see Resources). > Open the folder into which you downloaded the usbport.sys file. Right-click on the usbport.sys file and select "Copy." > Open the folder "c:\windows\system32\drivers." Right-click on the folder and select "Paste." > Click "Yes" when prompted to overwrite the existing usbport.sys file. Your Windows system directory will have the updated usbport.sys USB port drivers.> Restart your computer. The updated usbport.sys device driver will be active.
In case of ciruses/Trojan(Exploit:Java/CVE-2011-3544), firstly run an antivirus scan, and then you can use DLL Suite to fix BSOD and the associated dll errors, and it can also be sued for free download of the corrupt dll files. It is an easy to operate and efficient repair for any blue screen of death caused by .sys files.
