Every time turn on my pc, it powers off continuously in a cycle. It will turn and the re-boot every time. I can't even get to the login screen, and even when I do it re-boots immediately afterwards. Could somebody please help!
My pc specs are :

  • ■Asrock 970M Pro 3 AM3+
    ■FX-8370 with Wraith Cooler
    ■R9 380 XFX 2GB DDR5
    ■2x PYE 8GB 1800Mhz RAM
    ■PYE SSD 960 GB
    ■Windows 8.1 64-bit
    ■850 Watt PSU BRONZE 80 PLUS
I'm to nervous to attempt to leave the system on without risking damage to anything else within the build. Most of the posts that I've found involve booting up into the PC and actually running programs that aid me.
Thank you to anybody that supports some form of an answer to this situation. This is my second build.

Yes, the PSU is the most likely suspect in your case. A problematic or damaged PSU causes this exact behaviour. If you get a new PSU and you are still having the same issues then you should check your motherboard. I'd say it's 75% PSU, 20% motherboard and 5% something else. Also keep in mind that in some cases a bad PSU can damage the motherboard or other components. So if a new PSU doesn't work, it doesn't necessarily mean that the old one was OK. Good luck.

I just got it last week. Bought it new.
Also, how would one reset the CMOS? I'm not to familiar with PC's, but I am enough to build one.

Well, I didn't reset the CMOS, but I re-booted my PC and a new symptom appeared. The fans for the GPU were not spinning, and the monitor I had plugged into it was not receiving a signal, thus showing that the Graphics Card is not receiving power. Anybody have any ideas as to why this is happening?

What's your PSU? Is it a noname brand? Please post the manufacturer and model number, not just 850W bronze. That doesn't say anything about the PSU's quality. It seems that your PSU is a bad part. The fact that the GPU doesn't receive power points to the PSU besides all the previous issues which are also PSU related. Are you sure you have properly connected the PCIe power cable from the PSU to the GPU? In order to reset the CMOS, you have to read the motherboard's manual first.

It's by EVGA if that helps.

OK EVGA is a good brand and 850W is more than enough for your system, in fact it may be overkill.

Did you build this system? What's your experience level, have you ever build a system before? I'm asking because you didn't know what a CMOS reset was. Maybe you did something wrong during the installation process. Have you plugged all the required power cables? Maybe you forgot something.

Also you said that you got it last week. Have you ever been able to make it boot up successfully, or it had that behaviour from the beginning? That infinite boot process maybe related to a short somewhere in your motherboard. Did you use stand-offs during the motherboard installation? If you know what you are doing you should remove the motherboard from your case and start again the building process making sure that you don't do any mistake or forget something this 2nd time.

If you didn't build it yourself and just bought it in this state, you should return it back. Something maybe wrong with the PSU or motherboard.

Well, this is my second build and it was running just fine last week after I had finished it on December 24th. I was able to play Star Wars Battlefront with perfect frame rates, as well as a myriad of other heavy ended games such as dying light. This problem sprung up just today to. It started out as a random reboot, then the second time it had happened, it killed over and now I can't even get into the system. I'm going to return the PSU tomorrow and get a new model and hope for the best. Do you think you might be the PSU from what you have heard from me? I can't really perform a test on it because I don't have the proper tools and I have my college courses coming up real soon and I just want to find a solution.
I greatly appreciate your patience and what you have said to help me through this problem.

Why thank you again for your spectacular help! I do greatly appreciate it. If anything I'll report back here again after the switch is done, hoping that there was no damage caused to other components or hardware.

Okay, I found the main problem it was my PSU! I switched it out for a new one that I had and things worked perfectly fine, but again thank you for helping me out, you may have just helped others out to in identifying a problem.

It's strange because the GPU was supposed to be new, right? Perhaps you should consider returning the whole system to the store where you bought it and have them replace the GPU and also check the PSU. If the PSU isn't able to provide clean and stable power then it could damage various components including the second GPU and may be that's how your first GPU got damaged in the first place. Since this is a new system, you should be absolutely certain that your PSU is in perfect condition in order to avoid future headaches.
