My PC just stopped functioning properly after it has been running fine for nearly 2 years. When I turn it on, all of the case fans turn on, and I see the case LEDs light up. My Graphics card doesn't look like it's driving the monitor - I can see the fan on it try to spin up, but it stops after running for about 5 seconds. It then tries again, spins for 5 seconds, and then stops. It's a PCI-E card, and it has a power connector going to it.
I don't hear/feel my hard drives spin up either, which makes me lean towards it being a power supply issue, but I'm thrown off by the fact that the fans and case lights are working fine. Can this happen with power supplies? I have this OCZ GameXStream PS. I've seen on another answer that there are power supply testers, but I don't want to spend more than I have to. I might end up getting one anyway since I do plan to build again sometime.
