I bought this Processors at June 2006, Now its still running and my mb is 775i65GV the only problem is that my CPU gets over heated and the computer shuts downs, later when I opened it the case and there was lots of dust accumulated on my motherboard especially on my CPU fan so that's why it was shutting down and my Complementary metal–oxide–semiconductor (CMOS) has run out of its juice and the time is showing 2006 again so I called a local computer mechanic to clean of the dust on my CPU fan and the thermal paste was all dried off so i said that u should clean it with a soft cotton cloth but instead he just removed it with a screw diver and left many scratch mark and installed it again without applying paste. So what should I do... later on I changed my smps ram and cmos from where i bought my computer. And nowadays a new symptoms starting to appear (1st appeared on Jan 2012) When I am installing any pc game it just crashing and saying intel extreme graphics driver some system file is missing, later on i researched & found Blue screen of death. It disturbs me when I am doing any work graphics and when I am installing Windows, So what should I do ?
