I built this system about 2 years ago MOBO is MSI 7030 Video Card is Gainward 5900 XT 3 Hard Drives all connected SATA The D-Link has Three red Lights top 2 and bottom left are red, bottom right is off. The computer will not shut off unless I turn of the main switch on the back or unplug it. It will not post ne beeps. The monitor "On Lite" just blinks, I connected the monitor to my laptop and it's good. I have checked the connectors from the front panel switch to the "PWSW" header on the MOBO and the computer stays on if It's pluged to the mobo or not. I have shorted out the "PWSW" connector on the mobo it makes no difference. the system just runs untill I turn it off on the back or unplug it. This all started about 2 months ago, to get the computer to turn on I had to turn the main power switch on and of off to get the computer to boot. Then the front panel switch would not turn off the computer. Now when I turn on the main switch all the fans run the light come on the HDD spin up. I thought it might be my video card and switched it out with another. Same thing No Video - Monitor Light Blinks- All Fans Spin - HDD's Spin up. Everything sounds and looks good. But no Boot.
