Warning +5V 0.88V

mahaqmi · September 8, 2015

Hi guys, i just built a new gaming pc. specs:-

1) Asrock z97M anniversary

2) intel xeon e3 1231 v3

3) msi gtx 980 gaming 4g

4) kingston 1333Mhz 8gb ram

5) corsair spec-03

6) samsung 840 evo 120gb (windows 10)

7) intel 80gb ssd (ubuntu)

8) Western DIgital 1TB HDD (all other files)

9) XIgmatek 80 plus bronze 700w

All the hardware is upgraded from last time except for the PSU and RAM.

The problem is when i enter ubuntu the system seems to be fine but when i enter windows 10 there is always a warning indicator on the bottom right corner which says (warning: +5V 0.88V). This really makes me worry and when I install the latest driver for my gtx 980 my p hang and freezes half way and i need to reboot my PC. Sometimes my pc shutdown halfway even when entering windows 10 (died when the circle rotating on the enter screen). The problem doesnt seem to occur when I open my ubuntu though.

I really dont know what's the problem right now. I've done some google search and some says it have problem with 5V rail on my psu. I tried unplug the power on USB, then on each of my SSD and HDD. The problem still occurs. I really need someone help!!

Thanks in advance and im sorry as english is not my main language.
