Hello, over the past few weeks I have noticed that on occasion visiting Facebook or HTG websites causes my computer to lock up and the only way to get it running again is to ctrl alt del. The go back to the desktop where imidately both sites work fine. I am runny windows 7 64bit pro. Browser is Google Chrome. Problem is becoming more frequent, just now I had the cad twice in order to get to the options menu.
Any ideas warmly welcomed
