I own a AMD 64 3200+ processor and MSI rs480 motherboard, nvidia 6600 256mb graphics card , and zebronics lava cabinet and 512 mb ram in 2 slots. The problem is when i work above 15 to 30 min my system strucks but does not hang , its like mouse pointer strucks and even sound strucks when i set the side cooling fan of my cabinet to run, after few min the strucking stops. This things happens only when the temprature raises above 32'c is there any problem with the vent or this is due to over heating or whats the problem pls help me out...
