Computer random reboot even before windows loads up

[wbenz]

Hi,

 

I have a 4 year old desktop computer with ryzen 1700, 32gb ram, 1080 ti,

650 PSU and MSI x370 motherboard.

My computer was running fine, until 2 days ago, it reboots on its own without warning, sometimes it works for hours without rebooting but 2 days ago it reboots even when entering the bios settings or before loading windows.

 

I tried changing the ram stick orders, i also run a ram test with the windows built in ram checker with no errors.

 

I tried unpluging everything ( all the drives except the SSD that contains the windows setup) with no luck.

 

I tried changing the CPU thermal paste but the problem insists.

 

I checked the CPU and the graphic card temperature, they were normal (about 25 to 35 degre).

 

I dont know what to do with it as i need it for work .

 

Please help me !

Thanks in advance .

No surprise, that program is useless. Only way to be sure is run Memtest86+

But if it's rebooting before you hit BIOS, then you have bad hardware. I'd suspect the power supply first (after testing RAM)

I tried replacing the ram stick, the PSU, the graphic card and even the CPU but the problem persists, i think that this is a motherboard problem.

Any ideas ?

If you are certain the parts are good that you used to test with, then yeah, bad board.
