I have a problem that has stumped me so far, hoping you could help. I have a desktop that I built in 2007 that until recently has functioned perfectly fine. About 3 months ago I tried to do a Windows 8 consumer release install on it, and that didn't go so well. So I reinstalled Windows 7 on it, and discovered the problem. I've had other stuff going on so I haven't taken care of it yet, at least in part because I am at a total loss.
The power supply functions near as I can tell, and the motherboard appears to work (all LED's active). The power supply fans, the case fans, the processor fan, and the GPU fan all work. I have two HDD's and I can feel both vibrate slightly, indicating that they are active. The GPU connects to the monitor by DVI, and if the monitor is in standby it doesn't autodetect a signal and turn on. If the monitor is off, it doesn't detect a signal and turn on. If I turn the monitor on, it shuts itself off. The GPU card has two ports, neither produce a response. The monitor itself does work, as I can use a HDMI to DVI cable to connect my laptop to the monitor with great success. If it were a hard disk failure, I would expect to at least have the monitor detect the motherboard and show me the bios and what not.
When I was first troubleshooting the problem I remember that I did successfully get it to turn on (one time only) by swapping the two sticks of ram to the other pair of slots on the motherboard. It worked fine until I shut it off, but it would not turn back on. I have tried that method again, to no success.
My setup is a little outdated, relevant specs as follows:
ASUS Crosshair
AMD Athlon X2 4200
2X1GB PC2 6400
MSI nVidia 7900GT
Any insight into what happened here would be appreciated. There is no integrated graphics on my ASUS motherboard, so how can I distinguish if the problem is the motherboard or the graphics card? Would it be something else altogether? I also noticed that when I leave the power on now, the DVD drive makes a click followed by a "ramp up" noise every five seconds or so. This is a sound I associate with the computer turning on. Does this indicate some kind of looping power cycle?
