Power on, fans spin up, reset, and repeat..

[teknozx]

Hello. Recently built a new computer.

Raven RZV01
Silverstone SFX 450W PSU
ASrock Z97E-ITX/ac
i7 4790K
G.Skill 2x8GB DDR3 2400
EVGA FTW 970
850 Pro
Zalman Extreme Quiet
Windows 7 SP-1

Computer has been up and running fine for 2 weeks.

Wake up, try to to use the computer, it power on, the fans spin up and the powers down. Powers on, fans spin up, powers down. Keeps repeating in a loop. No idea what is going on. I've never seen anything like this. Reseated RAM, GPU, power cables. Jiggled everything back in.

Anybody have any idea what could be causing this? Thank you.

Did you clear Cmos? That PSU is pretty small, try a bigger one!

Yes, clearing the CMOS is something I would suggest. The up and down load sequence indicates there is a setting in the BIOS it is not comfortable with.

It could be a power problem. Can you find a spare PSU to check it out?

Thanks for the reply folks. I've been running it with the 450W for a few weeks without problems so far so it should be ok. Other people with the Raven case have said it was fine with the 4790 and 970. The PSU is gold certified if that helps.

I took apart everything down to the last screw and put it back together...seemed to have done the trick.

My best guess is maybe somehow a cable or something came loose somewhere that I missed. This case is so small and not too much room, have to be careful and make sure everything is plugged in properly and firmly.

Thanks again for the quick help. Thought my new setup was toast.

Keep an eye on it

that poor psu must be cursing you with its last dying breath.

but, it could both be that something has come loose (not impossible) and also the CMOS needs to be cleared, thats the first thing that came to mind.

you didn't overclock, did you? that would send the power requirements through the roof... of your PSU. at higher pull they start to have higher ripple, which could well be what is causing your PC to fail to startup.

that power supply is only bronze series ..if it was me i would up grade to gold or better..series in the 550 to 750 watt range..but i think it is a bios issue your having..can get an update flash for it ..and also try manually resetting the bios....then start from scratch resetting the bios property’s also this i have found so often causing your issue is incorrect ram settings..

Like others are suggesting, that PSU is rated at 80PLus. If its a bronze than your able to pull no more than 360-369 watts. That being said you may also be on the low side of you 12v requirements. Because it can run doesn't mean its not bending to the point of breaking.
