PC will not stay on....
So I got this for my mom for Christmas to replace her 10 year old computer, and I cannot get it to stay on. It works for a while, then whenever it goes to 'sleep', the power button blinks repeatedly, and it won't come on. Almost like you have to unplug everything, and plug it back in? Also, resolution is no where close to fitting the screen. Any help would be greatly appreciated, I don't want to have to return it.
