So one of my friends gave me a Thermaltake TR2 600w, and i tried to use it in my current pc. It is a Gateway GT5428 with a Pentium D 3.2 GHz. It didnt have the four pin plug for beside the cpu socket, so i bought an adapter and it works until I put the psu into my case. Then it makes crazy lines across the screen. After that i plugged y original back in and it worked fine. What happened?
