I was wondering if anyone could help me - basically:
I just setup a new system with a Z87-G41 PC Mate and a i5 4670k. I connected the 20+4 connector and the CPU connector and tried to boot. When I do the stock intel fan makes a rather loud noise (featured in the video) and keeps doing it for about ~20 seconds. Then the computer shuts down and it happens again. Also weird is once I shut off the power to stop the cycle the lights/fans flicker on for a few seconds.
In the front the lights do seem to go on and all the other fans turned on as well. I'm out of ideas at this point - I've checked the previously mentioned connections and everything ...seems properly attached and in place. Any help would be greatly appreciated.
I've attached a video, sorry about how bad quality it is (recorded it on my phone). Incase it comes up I did take preventive measures against ESD: antistatic gloves and the wrist strap/grounding myself.
It could be not seated all the way. Make sure the four pins are fully pressed in and snapped into place. Also make sure your RAM is fully seated as well.
If neither of those two work, remove the power cables from the motherboard (24 pin and CPU power) and unplug the power supply, then remove the CMOS battery (looks like a big watch battery on the motherboard) for a couple of minutes, and try again.
Well, gah. It seemed like it was doing the exact same thing but now after it restarts (after 20 seconds) it sounds normal. Fans work, lights work, etc. It stays on as well.
Of course now the motherboard won't make a beep (won't start) which is an even greater problem. I saw the guide for how to handle the no-beep but nothing seems to be working (RAM is new, power supply seems to work with everything else, etc...)
Any ideas (thank you for the help thus far, regardless)?
