Hello all, A few weeks ago one of my friends and I decided to build a PC for my dad, we both have minimal experience but my friend has built PCs before, I've helped others design PCs but I've never physically built one. Anyway, I checked everything out to make sure it's all compatible, technically it should work but we've run into a few problems. After connecting everything to the appropriate terminals and turning on the machine, I noticed that all of the fans, including the CPU fan, were in perfect working order, the case LEDs hooked up to the mobo work fine, and the mouse and keyboard light up when the PC is turned on. However, there is no response from the Disk Drive or Hard Drive, and the monitor claims there is "no incoming signal". All of the hardware is brand new, straight out of the box, so I'm not sure what the problem is. Any suggestions are most welcome, as I have four days to finish this thing. Here are the specs. There is no graphics card because my friend informed me that the particular CPU we picked out has HD graphics onboard meaning we wouldn't need a graphics card. The monitor is rather old and has a D-Sub connector, but it was working well last week and the mobo I picked out is compatible with D-Sub.
