It happened to me before and with help from the forum I managed to pin it down to AVG issues. Uninstalled it and everything ran smoothly until a few days ago. I know I did some updates with my antispyware software and also with the Microsoft Anti-Malware but doing rounds of disabling stuff I haven't managed to correct the problem so any help would be most welcome. I've run xperf as I was told before and this is the file with the result: CPU I have a Toshiba Satellite with these specs: OS: Windows 7, x64 Processor: Intel i7-3610QM @ 2.30GHz RAM: 16GB Sound: Onboard Realtek Video: NVIDIA GeForce GT 630M Cheers!
