Com restarting without warning

[leo0o0]

Hi guys, need some assistance with my com that has been restarting without warning at random timings, and everytime a restart occurs, it will loop a few times before I'm able to reach the login screen and login successfully.

This only started maybe at most 1 week before or so, and at most occur once per day. The previous times it will restart suddenly and boot loop just before the bios start up screen. Today morn when it happened I did a memtest and 1 pass was done with no errors, during the 2nd pass it restarted again and any attempts to run memtest will result in rebooting. I then reseated the rams and managed to run 2 passes with no errors.

After that I noticed my sata slot 0 seemed to be faulty after testing, so I changed my ssd to a different slot. That seemed to solve things for a few hours till earlier, when the com restarted for no reason again and this time the com booted till just before the windows login screen and went into a reboot loop for about 5-10 minutes.

I've moved the ssd to a different sata slot for now and I've no clue what's wrong with the com. Any idea or suggestion guys? Need my com to be stable and running for my projs and stuff :/ Reboot occurs when I'm doing light work, eg. microsoft office etc, nothing intensive like games etc.

My specs as follow:
Asrock H87 performance
2 x 4gb gskill ram
Samsung 840 evo 240gb
WD blue 1tb
Palit 970 jetstream
Superflower leadex gold 650w
Windows 10 Pro

Here's some info from Hwinfo regarding my psu:

Appreciate your input and any advice on resolving my issues. Thanks!

try remove gpu first and run onboard graphic than run a stress test
also remove your WD hdd and use only your SSD (OS) drive

Check your power supply.

Well could be either ur ram, mb, or psu that is cause those random restart, why not try to remove everything and left 1 stick of ram and 1 boot disk and boot up on POST and see if they can stable at post or not

Restart as in Windows write, Windows is restarting? Or straight boom, gone. If it's the latter, suspect is psu faulty. If got spare, use and test ba..

Can try cleaning ram first
If doesnt help then

Change motherboard or psu

ran prime95 on each stick of ram and both ran ok. However when attempting to run prime with both rams on single or dual channel leads to a reboot. any idea why? doing a memtest again now with both sticks..

update: completed 1 pass of memtest with both sticks of ram without error. however attempting to run prime95 with both rams in either of the dual channel slots or in single channel configuration causes almost immediate reboot when running blend test. now running prime test with just 1 stick of ram but with my hdd and dvd drive plugged back in.
so is it an issue with my rams, or with my mb or some bios setting? previously no issues with this configuration which has been serving my purposes well for about 1+ years

If u got spare mb can try it out else try to load ur bios to default setting.
