I've been working on this build since Wednesday and haven't ever gotten it to POST, let alone boot after hours of work troubleshooting, including running through the checklist that's posted around here. Right now the computer is set up as a breadboard on a piece of cardboard. When I try to power it on the CPU fan and case fans turn on for a fraction of a second, then switch off. Then it won't power on again unless I unplug it and then re-plug it and wait a few seconds. The first few times I tried to build the fans would stay spinning, but there was no video or beeps (even after trying VGA from the GPU or from the onboard video). I'm not sure why it went from that state to this one.
I was suspicious of the powersupply (carried over from my last build, about five years old), but plugged everything from my last build in this morning and it booted up just fine. The PSU does seem to be failing the paper clip test, but that could because I'm using a stripped twisty tie instead of a paper clip. Can a PSU be so old that it can power a full system, but can't pass the paperclip test? No multimeter sadly!
I'm using the parts listed below, but also have tried it with a different 3570k and a GA Z77X-D3H motherboard. I have tried everything I've read online, but haven't gotten so much as a beep or anything on the display. Any ideas?
Plugged in now:
Intel Core i5-3570K 3.4GHz Quad-Core Processor
Motherboard Gigabyte GA-Z77-D3H ATX LGA1155 Motherboard
Memory Corsair Vengeance 8GB (2 x 4GB) DDR3-1600 Memory (I've tried without the RAM, but don't get the beepbeepbeep I'd expect)
Power Supply OCZ Stealth 600W
(Also have 2 HDs, a GTX 670 and an SSD, but those aren't plugged in).
