Help! I just had this problem with my PC. I fiddled with some power options, like turning off the harddrive after a certain amount of time, because I tend to fall asleep in front of the PC while watching a movie or playing games. Anyway, I tried to "wake up" the computer by moving the mouse as one usually does when the PC is on standby. It wasn't "waking up" like it does usually; I noticed the green power LED and the HDD LED were both lit up for longer than usual. I tried resetting it by pushing the reset button but that didn't work so I turned it off by switching off the power supply. I tried turning the PC on again but the monitor didn't turn on as expected. I noticed the green power LED wasn't lit, although the red HDD LED was. I tried several times to turn the PC on to no avail. Can anyone help me with this? I have no idea what the problem is and would appreciate any help, even if it's just a nod in the right direction. Thanks.
