Hi AlienwareOwners. This should be a good question. Ok my Samsung PX2370 Led monitor occassionally goes into a complete black screen. I could be gaming, surfing the web or just booting up the computer and it will sometimes black out. This has happened on occasions not every time since the last year till now. Everytime it happens the desktop is still running but I will get no functions from the mouse or the keyboard it won't even get a beep when I hold down the keyboard button. I try to press alt delete control keys and nothing will happen. I would then manually shut the power off then I disconnect the power cable and press and hold the power button for a complete reboot after that the system works fine again. Like I said it happens occasionally not all the time I have no clue why it's doing that can someone please explain. One of my friend who is actually good with computers said it could either be my Gpu or my monitor causing the issues or my USB plug. What am I to do I'm not an expert in computers so any help would appreciated, thank you and cheers!
