While playing through Crysis 2 there was an audible popping sound and feint smell of burnt plastic and my computer went dark. There is nothing happening when I try to hit the power button. I opened up the case to see if i could find out what happened and didnt see anything right away. the smell is coming from the graphics card or power supply area mostly, but am not certain that is were it is coming from. I am thinking of removing each unit to investigate further and thought it would be wise to check with the pros before proceeding. Is there anything I should know or are there any ideas what could of happend? I pieced together the computer myself but havent had any problems like this before so Im trying to obtain advise about what to do next. Thanks in advance.
