hi, i have a hp g62 with core i3 and 4Gb of RAM memory, bought last October
since some weeks ago my pc is lagging every time i play any game that run perfectly before, i thought that such situation was due to overheating (and it was, but i didnīt realize why...) but today i turned on my pc and without running any program i went to the task manager to see what processes were running, and nothing but the antivirus (NOD32) and msn (the programs that consumed more ram), the other programs where insignificant because they are from system. then i see the performance and "woooow!" 1.3 or 1.4 Gb of RAM consumption! i run the antivirus many times, the "TuneUp utilities" and "malwarebytes". at first they detected some errors and some trojans, then i fixed them and restarted the computer... after restart: the same memory loss as i mentioned above... so, what should i do?
