Hello Everyone, I really don't know much about computers but I do know smoke probably isn't good. Here is my problem. My computer was broken and a friend told me to replace one thing. The CPU heatsink. I didn't really know how to place in a new one but I figured I could do it. It was pretty fun but I ran into trouble. I bought this things... http://www.newegg.com/Product/Product.aspx?Item=N82E16835114055 I took off the old one and put some new glue on the CPU because I touched it and it was gouwy.The holes didn't really match up so I made my own. Then it still didn't hold so well so I put on some tape on the sides. When it was finished I put the side of the case back on and tried turning it on. It turned on and was good but I smelled burning and something sounds like it was flying around the inside hitting the sides for a little bit. Then it went away. I keep the computer on and there was a little black smoke coming out the back and sides. I thought if I could turn up the cpu fan it would speed up but I didn't really know how to do it. I went into the blue screen thing and turned the cpu up from like 3000mhz to 4500mhz... after that the plug started sparking and power went out in like the whole house! There was a lot of smoke so i ran outside for the garden hose and started spraying the computer through the vents. Everything cleared out and I tryed turning on the computer again but it would not start. Please help! Thank You Everyone! Oh I almost forgot the specifications!
