Computer freezing with loud buzzing noise, takes forever to boot to login.

CPU: Intel i5 6600k
Motherboard: MSI Z170A SLI Plus
Ram: HyperX FURY 8GB (2 x 4GB) 288-Pin DDR4 SDRAM DDR4 2400
SSD/HDD: SAMSUNG 850 EVO 2.5" 250GB
GPU: NVIDIA GeForce GTX 970
PSU: EVGA 600W Bronze

I started having a problem where my computer would randomly freeze (I always have Twitch streams running and/or playing games), and emit a loud buzzing noise from the headphones. I would have to do a hard shut down and restart. This still happens periodically and I don't know for sure what causes it to happen. I've also had the screen turn white and freeze with no noise, but this only happened once.

Now onto the slow boot up: this only started happening recently, after the freezing problems started. Now when I reboot my computer, even if I do it normally through the start menu, it takes forever to get from the welcome to windows screen to my login screen. For about 15-30 second the screen will be black with my only my mouse cursor visible before giving me the login screen to access my desktop.

Does anyone know where to begin diagnosing these problems? Are they related?

  1. Any ideas? I can post more system info if needed, just tell me where to find it.
    I really have no clue where to begin or whether these problems are related or separate. I don't know if it's a software or hardware issue. The lockups also happen while I'm AFK, when I have a stream and/or game running.

    I built this computer about 9 months ago, all new parts except for my PSU which is several years old by now. https://www.newegg.com/Product/Product.aspx?Item=N82E16817438014&cm_re=evga_600w-_-17-438-014-_-Product

    Also if this would be a question better asked on another subforum, let me know.
  2. Well I figured out the delayed login issue - it was Bitdefender 2017. That problem went away after I reinstalled it.

    Now I just have the freezing problem with the buzzing noise.
  3. The freezing problem with buzzing in headphones could be due to a faulty graphic card.I had a similar issue with my Radeon 6670HD 1GB- had to change it. It could also be due to PSU not supplying enough power to graphic card causing it to reset.Is there a way you can check your graphic card on another system? Or check your system with a different PSU?

    I was thinking it was either the PSU or GPU as well. The only thing is it's hard to test because it happens sporadically, sometimes it won't happen for a week or more, sometimes it happens twice in one day with no special circumstances. I only have my one desktop so I can't really test the components in another system unfortunately.

    Are there any tests you would recommend for testing either the GPU or PSU for faultiness? I wouldn't mind buying new parts but I'd like to know which one I need first. What are the chances it could be a MOBO issue?

    One other thing I should mention is that the electricity in my apartment shorts sometimes, particularly when there are too many things plugged into one area of the house causing me to have to reset the circuit breaker. Could bad electricity be a culprit?

    The best solution is to go to a pc store and request the person to test it or just send the GPU for repairing (is it under warranty?). There are softwares to detect error but I don't know much about them.
