nt kernel& system hog my cpu

Hiya and welcome to Tech Support Guy :)

Sorry for the lateness in replying, these forums can get very busy. Are you still having this problem? If so, can you do the following:

Download Security Check from here.

• Save it to your Desktop.
• Double click SecurityCheck.exe and follow the onscreen instructions inside of the black box.
• A Notepad document should open automatically called checkup.txt; please post the contents of that document.

---------

Download OTL to your Desktop


(Vista or Win 7 => right click and Run As Administrator)

• Double click on the icon to run it. Make sure all other windows are closed and to let it run uninterrupted.
• When the window appears, underneath Output at the top change it to Standard Output.
• At the top, check the box entitled Scan All Users
• Toward the bottom, check:
  All Users
  LOP Check
  Purity Check
• Under the Standard Registry box change it to All
  Do not change any settings unless otherwise told to do so.
• Please copy the text in the code box below and paste it in the Custom Scans/Fixes box in OTL:

• Click the Run Scan button. The scan wont take long.
  A black box will appear, this is part of the custom scan, so don't be alarmed ;)
  IF OTL SAYS 'NOT RESPONDING' DON'T USE THE MOUSE. IT WILL CARRY ON SCANNING AFTER A FEW MINUTES
  
  
• When the scan completes, it will open two notepad windows. OTL.Txt and Extras.Txt. These are saved in the same location as OTL.
  
• Please copy (Edit->Select All, Edit->Copy) the contents of these files, one at a time and post them in your topic
  

Thanks
