I have dell laptop with Intel Core Duo P9400 2.4GHz 4GB RAM. Windows 7 64bit. every day in the evening i meet problems with my CPU used at 100% system are freezing and sometimes even mouse is not usable, sometimes system gets critical error(blue screen). i used nod antivirus(up to date) run scan it didn't find anything, i tried dr. Web the same result(nothing suspicious was found). i searched on the internet for same topics and i found ComboFix i tried it. ran it, I am not sure but appears to be ok(nothing suspicious). Not sure because I can not interpretate report which was saved. i used procexplorer and aplication which is using the most of processor resources is random(can by skype, can be opera or mozzila firefox). Please help me, maybe somebody already met such a problem, reinstalling Operating System in my case is the last solution which i would like to avoid. i observed that this problem has periodicity(it appears in the evenings and i am using computer all day. in last a few days it starts to appear sometimes in the morning)
