This is a recent build:
AMD64 3200+ 2.0GHz single core
DFI Ultra-D LanParty non-SLI
Seasonic 600w power supply
2 320GB Western Digital hard drives in RAID mirror
ATI x800xl 256MB video card
2GB OCZ 3200 RAM 2x1GB
Antec P180
Linksys 802.11g WiFi PCI card
For a few months the computer has been ultra reliable. The first hiccups were that it would occasionally start up but the fans would not slow down and the computer wouldn't start. When it works the fans will go full steam at the beginning and then slow down to normal. Also occasionally the computer wouldn't start, but unplugging the PSU and re-plugging it in helped sometimes, and just repeatedly pushing the start button really hard would make it start if you got lucky.
After work I went to CompUSA to buy a power supply tester, and here are the results. When I plug in the 24 pin ATX connector, apparently all 7 lights are supposed to light up:
+5V
+12V
+3.3V
-5V
-12V
+5VSB

Well they all light up EXCEPT -5V. When I plug the 24 pin cable, the P4 connector, and a molex cable into the extra space on the motherboard, and then press "power" ... it tries to start up but then isn't able to. The PSU fan seems to spin continuously while the 24 pin is connected to the tester, but can only run for a second when plugged into the motherboard.
Luckily I have this old P3 1GHz lying around which is what I'm using now, so I tried plugging that 20 pin connector into the PSU tester. All 7 lights light up.
So is the problem I've been having very likely 100% PSU, or could the motherboard be a factor? Also could somebody please explain what's going on?
