PC stuck in boot loop

[brutalbuck]

Hello,

For the past few weeks my PC has been randomly restarting on me for no apparent reason. I have not received any error messages or blue screens, it just reboots. This has happened under moderate load while gaming and light load while browsing. Last week it restarted and was stuck in a loop where it would power up for varying times between 0.5 - 5 seconds and then cut off. I left it for about 24 hours with the power cable disconnected and I finally received an error about the CMOS and was able to turn it on. 

I still had the issue with the random reboots, however. I ended up updating the bios and left it until this weekend until I could do some testing. Well, I turned it on today to be greeted by the same boot loop.

I've tried resetting the CMOS by removing the battery, replacing the battery, and hard resetting.

Not sure if this matters but at one point I forgot to connect the CPU power cable before attempting to start it and everything ran for about a minute before I turned it off and reconnected the cpu power.

Symptoms indicate overheating

Please blow dust out of power supply, motherboard and video board.

If you do not have any temperature sensing apps then install tthrottle

and monitor temps looking for problems.  Post back here is temps are high

Your system came with windows 10.  Please run the hp support assistant and look for updates

Check the support assistant and see if your bios is dated 2022

I have gotten the PC to boot again, although I'm sure it's another fluke. I replaced the PSU and it still power cycled. 

I still have the random reboot issues and the temps on both CPU and GPU have not even reached 80* C.

I originally thought it was an overheating issue as well but the CPU and GPU withstood stress testing. However, it still reboots at random whether while gaming or while doing menial tasks.

This does not sound good and I assume the system is out of warranty and you have blown dust out of the motherboard, cpu heatsink and gpu fan area.

I assume you have the I7-10700F Intel cpu.  Googleing I read the max core temp allowed is 100c but I also read that the maximum case temp is not to exceed 72c.  There are a lot of complaints about overheating and several mentions that the CPU is designed for use in an office.  Office game are typically spider solitaire 

Please verify that you have bios versions dated March 20, 2022

If you need to update your bios be sure to verify the ROM SSID as there are two versions of the March 10 bios

you will need to select win11 and 21H2 to see the two bios

The 10l700F is rated at 2.9ghz with a boost speed of 4.8ghz  Please ensure you are not running a turbo speed all the time

Your processor power plan should have minimum set to %5.  I recommend you set the maximum to %75.  If the system seems to be more stable then you might raise the maximum to %95 but I recommend never using 100% 

Another possibly option is to disable hyperthreading in the bios.  The 10700F has 8 cores. With hyperthreading enabled you are doubling the workload for each core and could be spiking the temps above 100c

Did you try tthroggle?   Please verify the tjunction temp is 100c.  You might set it to 95c like I did to be safe

The app will control the temps by throttle the cpu and gpu to prevent overheating if "Auto Active" is enabled.

There are probably  better temp sensor and control app but I use tthrottle on all my  windows mining systems.

MSI's afterburner fan control will handle you 2060 NVidia better but I suspect the problem is the cpu

change 100% below to 75 then increase if system seems stable
