Not really, I have Sypbot without teatimer, I do believe I disabled windows defender. Anything you would suggest or know of anything that could cause this? This started a while ago and I have been dealing with it, even reinstalled win 7. At one point I even almost thought it was a hardware problem but WinPe, windows 7 install and ubuntu have had no problems at all on this same machine. Then when I uninstalled avast the problem stopped, reinstall and it started again..
