Motherboard Causing Random Reboots

[stairsrcool]

Recently my computer has been experiencing random shut downs, It would shut down playing games & it would turn right back on. Sometimes it would shut down when I'm just on the internet & even shuts down when I'm on the bios.

I've ran multiple stress test on the CPU to make sure it wasn't the problem & also have switched out CPU's. Then I tested the power supply to make sure it wasn't the problem, switched power supplies but still getting the same problem. After settling this I then checked my ram sticks & it turned out all of them were fine so I narrowed it down to my motherboard being the problem. I've taken the CMOS battery out & also tried the jumper. So I have no idea what to do with my motherboard is there anyway to fix it or am I just better off buying a new one instead?

hope you guys can help currently using an old motherboard of mine for my computer at the moment.

Geforce GTX 1060 3gb
12GB DDR3 1600 Ram

The problem may be from the CPU/GPU overheat, or PSU, or the driver, or the hardware will fail.

Check the windows event log to see any error info that will help you find the problem.

And try update the BIOS, drivers, like chipset, GPU. Because you try two PSU, so the problem did not related to the PSU. But it does not hurt to check it out, you can go into the BIOS, in hardware monitor or PC health monitor section, check the +3.3V, +5V, and +12V. You want to see those voltages are within +/- 5%, eg. +3.3V, you want to see the number should be within +3.1V to +3.45V.

For the GPU driver, using DDU to uninstall the drvier in safe mode first, then reinstall the GPU driver. Check the HDD with HD tune.

Test the RAM one by one with MemTest86 https://www.memtest86.com/download.htm

If you try those things, and you still have the same problem, it looks like the problem is from MB.
