Hi,i have an Neo Elan laptop.(quick specs-i7,quad core,750hdd,4gb ram,640M-NVIDIA-2gb).My anti virus is Bitdefender 2011,it says that there is no virus detected. I am not satisfied with the performance of my laptop,i think it process slow for an i7 processor,,it speed is just like an i3. .How can I maximize the perfomance of my laptop?.any suggestion?
