I bought all the parts, put them together, and…nothing.
This isn’t my first time assembling a computer. It’s my third full assemble, and I’ve done loads of upgrades, replacements, adding parts, etc…My first build was the only one that never had any problems. The second one went wrong because of a bad hard drive (I originally thought the MOBO had a SATA problem, but it was the SATA drive.) This one…I have no idea.
Nothing happens when I press the button. Nothing at all. No fans go, no lights turn on, no beeps. Everything from the power supply is plugged in. The ATX power connector, the extra 12v CPU connector, the PCI-E power connector for the video card, and even an extra MOLEX power connector on the mobo that it says is only needed if I have SLi, but when nothing worked, I tried that too.
The power switch is plugged in the right spot, and I even unplugged it and shorted out the connectors to see if the switch was dead…nothing. The mobo isn’t shorted out to anything, every standoff screw I put into the chassis was used, so that’s fine. I removed all the cards and cables, including the CPU, and put the all back in…still nothing.
The only thing I can think of that could be bad is the power supply, but I have no way to either test it or a spare PSU I can use (I know my current PC’s PSU doesn’t have PCI-E connectors (thought the vid card came with a molex adapter,) but I know it doesn’t have the right ATX power connector (the new one has four extra pins.)
Does my analysis of the problem seem accurate? There is a small LED behind the power switch on the back of the PSU, and it does turn on, so it’s getting power, and can do something with it, but I have no way of knowing if it’s getting to the mobo.
