ok went on vacation for about a week. The computer was off. Now the computer basically stays on so it appears. The blue LED lights/fans on the front and back stay on, the dvd burner, dvd rom drive both open, the only way everything shuts off is if i flip the power supply switch off. All i see is a black screen when the system is on. the PC Activity button on my modem is on, so the system is on. How can i tell if my moboard is fried? any guides or troubleshooting tests? Again i cant turn my computer off....even when holding the power button for a long time, only way i can get it to completely shut off is flipping the power supply switch in the back. Monitor is working fine as i just put my old cpu that im typing on now to post this with the monitor. All my lights are on, monitor is on, but i dont see anything. thanks for any help.
