I recently bought some new upgrades for my computer including a motherboard (Gigabyte Z77M-D3H), a CPU (Intel Core I5 3330 Ivy Bridge), RAM (Corsair Vengeance LP 2x4GB) and a Hard Drive (Western Digital 1TB). I have a problems where my PC keeps freezing at random intervals and it makes a sort of tssss sound and all I can do is restart my PC. I brought the new hardware back to the supplier and they tested it and said it was all working fine. I have also had It in and out of numerous repair shops and it still hasn't solved the problem please help. I also have a 650W Corsair Power supply and a GTX 460 SE Graphics Card
