I have a HP Pavilion t560i (3 GHz, 512 RAM, Intel 865g mobo). I bought a BIG Geforce 6600 GT AGP Version (128 MB DD3 video memory) today to replace my Geforce 5200 XT. When I plugged it in and it was working just fine. But suddenly my cabinet started giving a current. Yeah I got to know that afer getting an electric shock when I touched a metallic part!! Panicking, I quickly turned the computer off and unplugged all the cables. However, there was still a lot of static charge there. I waited for 5 mins but the current was still there. Then I kind of moved my cabinet and the current suddenly went away. Quite sure that my new graphics card is messing things up, I replaced it with my Gefore 5200. However, the current still comes in intervals (when I move the cabinet again). What might be the problem?? A loose connection? Please note that the 6600 GT had to be connected the SMPS. However the 5200 didn't need this. Does the problem lie here?
