I have just built my 3rd PC .But ,this one worked fine for about 3 days and now boots ok but at the end of POST..a blank screen..it does'nt say no signal or restart and my standby light is green as if windows is loading but I cant see it !. The HD is running .I have changed the RAM config and also run it with 1- 5I2 stick and removed the 2 -256s and vice-versa. I have also changed Graf card..and HD cables,,and PSU! and re-installed the CPU and fan...Its a mystery..Any Help please
