Still having problems, i realized that i had ordered the wrong memory so i re orderd the right part. When i attempted to start it up before installing new mem the all the fans would kick on for about 1 second and then turn off with no real fan noise coming from CPU. But now after everyhting is connected the fans turn on now for about 3 seconds with cpu fan noise and all seems well then it cuts out again... im getting really frustrated. I have also tried unplugging components except vid card mother board and CPU but then it turns to doing the same 1 sec turn on. Any advice would be much appriciated.
