I made a post a few days ago regarding the issue and came to the conclusion that it was the power supply, but after dealing with this for a couple more days and doing more research i am starting to have doubts that it is my power supply and i am thinking it is an issue with my motherboard. So basically what happens is whenever i start up my system whether it be idle in bios or in windows playing a game it shuts down after EXACTLY 30 minutes, the fact that it is happening after EXACTLY 30 minutes is what leads me to believe that it is not a motherboard issue, i am also pretty positive that it is not a heat issue because my system is running cool; motherboard temps are 40c CPU around 35c and GPU around 35c as well. My power supply is about 6 years old now so i am going to be buying a new one soon anyways so i will be able to test that, but before i call up MSI and send in my motherboard i just wanted to see if i could try to fix the issue here. Another thing that might be relevant is if i just press the reset button on my case (which leaves everything powered like my fans) it resets the timer so it wont shut down for another 30 minutes. What i have tried Updating BIOS. Reverting to previous BIOS. Taking out CMOS battery in motherboard, powering the system on, powering the system off, then putting battery back in. Leaving system in BIOS. Unplugging everything plugged into the back of my system, keyboard, mice, ethernet, ect. Anyways just please get back to me with anything i can try because i would really like to just give this a shot at fixing it before i send in my motherboard and cant use my computer for however long it takes to get it fixed or get them to ship me a new one. Let me know if their is any information you need for me to get and i will try to get back to you as soon as i can, and thanks ahead to anyone who helps; i appreciate it.

I have been using it playing hard to run games for about half a year so i'm pretty sure it is not being overloaded. I have also used it the last couple days playing games for the 30 minutes and it still doesn't restart before then. So should i look into getting the motherboard sent into MSI or Newegg so i can a new one that doesn't have this issue?

Try this too go to bios to config and disable VLAN device maybe that network adapter is actually broken

if it doesn't work either then send it back cuz is broken

not the board itself is broken but the bios.If you can flash it with an older version

Hi @Joecake welcome to the LinusTechTips Forums.

I'd suggest making a new thread to discuss your issue, if you want you can reference this thread and parts of this thread but you're unlikely to receive responses on a thread 4 years old.
