Need help here ASAP. I just turn off my computer after 4 days of on to make it rest for a while. Just after 3 hours I decided to turn on it back, but there is no response when I switch on its power button. Any idea here? I have change its power supply and it's not the power supply problem. Could it be my windows 7 effect it cuz I just flash my bios with SLIP 2.1.
