hey, I have a problem starting up my gateway desktop, I'm not exactly sure of the specs, but when I was going out for a bit, I put it in sleep mode, and when i came back, I tried tapping the keyboard and clicking and moving the mouse, but then it didnt work, so I shut it of manually and then tried reseting. Whenever i try to turn it on, the start button blinks, and the moniter stays black. any ideas? sorry if this seems vague...
