Since last 3- 4 months my pc randomly restarting without even bsod no matter i m playing games or m not using for any task. It restars at any time. No fixed time. Sometimes it works for several hours without any restarts sometimes it restarts even after booting . So i m trying to identify what is the problem. I have almost checked with many components but still same problem. At first i changed my cabinet case as i had 11 years old cabinet as i though some problem there might be of those wire.After that i thought may be ram problem but so checked with other ram, then i removed my hdd and bought new ssd and tried with it. Then i suspected it was may be mother board or processor so i checked with different mobo and processor combination still the problem even i sent my mobo to service center for checking but it returned as there was no issue. Even cleared cmos also. I had a foxin 900 fps psu so i thought may be psu is the curlpit so i just bought new psu corsair VS 550 and using it for last 2 days. I used it for few hours in last 2 days now but as it was running without restarts so i thought my problem is solved but in last 2 days i got just a single time restart problem so now i m worried.

My current specs:
Mobo: Motherboard A68HM-S1 FM2+
Processor : AMD APU A8 7600
GPU : MSI GTX 1050 2GB DDR5
Ram: 2x 4 gb ddr 3 1600 fsb.
PSU: CORSAIR VS 550
SSD: KINGSTONE UV 400 120 GB
HDD: TOSIBA 1 TB
CABINET HAS A LED FAN, NON LED FAN AND 2 LED STRIPES.

So what do u guys think there might be issue in my electricity switch board.?

Note :almost my all components are less than a year old.
 
Random reboots or shutdowns are mostly caused by 2 issues:
1. CPU/GPU overheats and to prevent any damage, system shuts down.
2. PSU fails to deliver enough power to the GPU or fails to keep smooth enough voltage for PC's operation.

First check your CPU/GPU temps, both at idle and under load. If temps are within reason then it's safe to assume that it's the PSU who is acting up.

Note: Corsair VS series is the worst PSU offered by Corsair and it's a low quality PSU. I wouldn't use it to power even the low load office PC where PSU never sees any high loads, let alone powering a gaming PC with it.
 



As i have already mentioned i have checked with different PSU & all different components .And mine is not a that much high-end gaming rig. This PSU is brand new as i thought there was a problem with my previous Foxin brand PSU so i bought this recently.. I think The problem is Windows 10. I m now using Dual boot Windows 7 & Windows 10 just to check if i face same problem in Windows 7 also. After installing Windows 7 till now no Restart issue happened though i am not sure, i must keep checking for this problem for with windows 7 usage. i will keep posting updates. One of my relative is also getting same kind issue (restart/shutdown) & he has also Windows 10 & same Processor. I dont know there is any bug with APU series processor & windows 10 or not. need to check for this.
 
When it comes to the PSUs, they can be classified into 5 groups according to their build quality: great quality, good quality, mediocre quality, low quality and crap quality.

Just because your PSU is new doesn't matter is good quality and works without issues. Your Foxin PSU is crap quality, while your Corsair VS series PSU is low quality.
For any kind of gaming rig that had dedicated GPU in it, i wouldn't use anything short from good quality PSU. And if budget allows, i'd use great quality PSU. Though, for office PCs that doesn't have dedicated GPU in them and where PSU never sees any high loads, at worst, i'd use mediocre quality PSU but only when there's no good quality PSU available.

Anything from Seasonic lineup is either great quality or good quality, while Corsair lineup starts from great quality (e.g AXi) and ends with low quality (e.g VS). And since PSU is the most important component inside the PC, all my 3 PCs: Skylake, Haswell and AMD are powered by Seasonic units (full specs with pics in my sig).

If you truly believe that what you have is a software issue then feel free to follow those paths. Maybe even make a topic at the Software -> Win 10 subforum, rather than Hardware -> Components subforum. But consider this, if it isn't a PSU issue, you should have the exact same frequency of reboots with Corsair VS as you had with Foxin.
 


I think i must put another thread in Software > Windows 10 as you said.Today i checked almost 14 -15 hours continuously running on Windows 7 & its still running & its good that within the 14 Hours - 15 Hours run there was no such issue till now . At least i can say after installing Windows 7 there is no issue till now but my search is still going on :)

 
I uninstalled all my Windows 10 Version 1709 & Windows 7 both . Reinstalled fresh windows 10 latest version 1803. Previously I had installed windows with Native IDE SATA MODE which was by default in my motherboard bios so this time I installed with AHCI SATA configuration. Now everything seems good with windows 10 also. I don't know if previously Native IDE SATA configuration had any issue with windows 10 or not but it was running fine with windows 7, but now with AHCI everything is perfect . :)
