I recently bought all the parts for a new system and finally had the time to put them all together, with not as much luck as I'd have liked. Below is my problem...sorry if it's long, but I wanted to include as much info as I could.
Specs for my system:
CoolerMaster CM 690 case
Raidmax RX-530SS psu
Gigabyte GA-P35-DS3L
c2d e4500
2 gb OCZ Platinum rev. 2
Powercolor x1950 pro 512 mb
samsung sata dvd/r
WD 250 gb sata HDD
~8 last night, here's what happens: I have everything plugged in, hit the power button on my case, the fans/LEDs start/light momentarily, for about a second or two, then turn off, then on again, off again, on again, and so on. If I try to turn the computer off with the power switch on the case, nothing happens, I have to hit the switch on the power supply in order to power down. Also, when the computer is trying to run, there's a faint "bzzzzt" noise when the fans/lights are on. My guess is that I have a faulty PSU, already have gotten an RMA number from newegg, but ask some questions around, and fiddle some more.
around 9:30: Hmm...OK, maybe progress has been made? Just went and checked the front panel connections, turns out I had the power LED on the CI connection. I moved the LED to the proper place (it has 3 prongs, but my case only has a socket for 2...just put it on there anyway). Plugged everything in and hit the switch...same thing fans on for a second, and then off again and the weird "bzzzt" noise. I scooted the case over a little bit to get a better look inside to see if I could pinpoint the noise, and lo and behold, the lights and fans stayed on! And then turned off again. I hit the power button again, it did the on/off/buzz for a second, and then it turned on full steam, the computer started to boot up and I at least got to the "insert system disc" prompt. Troubling thing I noticed though...as everything seemed to inexplicably be running smoothly all of the sudden, one thing that wasn't working was my cpu fan. Made sure nothing was interfering with it, but it all looked clear.
It was suggested that I pull the mobo out of the case, and hook the essentials up, to see what happens. I might try that later, but it was more than I wanted to fool with last night, but I did try unplugging the ATX_12V connector, b/c I had to stretch it way over my videocard and close to the cpu to plug it in (the PSU is on the bottom in this case). With that unplugged, I tried firing it up again. It did the on/off thing once, and then turned on, cpu fan running and all, BUT this time, there was no video signal or any sign of BIOS or anything, and the power/reset switches were unresponsive, had to power off with the PSU switch. Tried it again, same thing happened. Then I unplugged everything, reattached the ATX_12V, plugged everything back in and tried again. Started up OK (might've done the on/off thing...they all blend together now), but got to the boot screen at least, CPU fan was working and everything. Then all of a sudden, the computer shuts down. Try it again, same thing. Try it one more time, it does the on/off thing for maybe 7 cycles or so, and then everything appears to be running, but no video output and no response of the switches anymore. I think even if this PSU isn't DOA, it's still a POS. The ATX_12V connector JUST BARELY is able to plug in, and I'd need to rig up something to keep the wire out of the CPU fan (had to manually hold it out of the way in the latest test batch.)
Sorry for the huge post, but like I say, I'm guessing it has to do with the PSU. If anyone has any other guesses though, I'd sure like to hear them. I figure headaches are inevitable with a new build, but I've never experienced problems quite like this one before.
