I am running Windows 8 Pro. I put it into sleep mode several times and now it seems like it will not wake up. I tried powering off and then back on but no display. It doesn't sound like it completes the power up.....like it can't get out of sleep mode. I have a Corsair case which normally lights up on start up but those lights are not appearing when I power on. The display I am using works on another computer. I am using a Gforce video card with DVI.
It is hard to troubleshoot since I can't see anything. any ideas????
