I am having some trouble with my PC. When I turn it on, there is a little light on the front that turns on, but the main power button doesn't light up. I opened it up and can see that the psu fan is working, but the cpu fan does not. My wireless pci adapter powers up, so I know that the mobo is getting power, but the cd/dvd drive doesn't open. My monitor says it is not receiving a signal, but I have no idea what the issue is. I checked all connections from the psu to the mobo and other hardware, and everything seems intact. Can anyone offer some insight.
