I have some strange issues with my PC and hope you can share some advice of how I might fix it. Let’s start from the beginning, the PC is new – I got it around 3 months ago and this is the configuration:
• Gigabyte X99 – Ultra Gaming
• Intel Core i7 – 5820K 6 core
• Gigabyte NVIDIA GeForce GTX 1080
• Samsung SSD 850 EVO 500GB
• WD 2TB HD
• Antec High Current PRO 750W
• Nepton 240m Cooler Master
• G-Skill Ripsaw’s DDR4 4 x 8GB
On this I have Windows 10 64-bit installation.
So my problem is when I turn on the PC for the first time during the morning, the coolers after few minutes go to max speed, and after a while the PC is unresponsive and turns itself off. This happens only when I turn it on for the first time in the morning after it was off for the whole night, the air that was flowing was cold. If I manually turn it off while pressing the button, and turning it on again right away…the problem goes away and the PC works normally during the day. So it only happens when I turn it on for the first time. I installed Open Hardware Monitor and checked the temperature readings right after the Windows starts - they begin from around 30c and go all the way up to 80\90c in few minutes. So I turn it off and on, and it will work all day with around 30c temperature.
I don’t think it’s a Windows issue, since the cooler goes off even if I don’t log in to Windows and I leave it to the login screen for few minutes. If I restart the PC from the Windows Start Menu button while the temperatures are spiked then the coolers will remain in full speed when it reboots, and even in BIOS the temperatures read at around 80C. So the only way I can fix it, with hard press of the button. So I am doing that 8 out of 10 days….since there are some days which it boots up without a problem.
I contacted Gigabyte about this, they told me to update the BIOS (which I did twice…from F4 do F5, then to beta F6) but the problem remained, then they told me to take it back from where I bought it and change the thermal paste. I did that as well, and the guys from the store did thorough testing, with different hardware, changing of the thermal paste, cleaning of dust (even though its only few months old). The strange thing is - they didn’t have one temperature and cooler issue like I do when the PC is at my place.
I have to specify that the PC is not covered with anything and it has good ventilation. I tried plugging it in a different socket, tried it with another power cord cable, but again today the temperatures went crazy.
I am going to attach some photos so that you can see how freak of a problem this is.
Hope you can give me some helpful advice
