Random Computer Reboots

[tech covered in jam]

Hey Linus Tech Tips Forum....

 

I have been expereincing an issue over the past 5+ days which has reallly got me and I can see no more solution for. Essentially my PC reboots without warning and with no obvious cause.

 

Computer Specs:

• i5-4670k (stock speeds, don't kill me for the K)
• MSI GTX 760 (stock clock)
• 8GB Corsair Vengence Memory
• MSI Z87-G45
• Corsair CX600M
• OS Drive - 240GB Kingston SSD; Storage Drive - WD Black HDD 1TB
• Windows 10 - 64bit

 

When I say the restarts are random, they really are, for example, it can happen when playing a game, when browsing the web etc. However it did in the past cut out as soon as a benchmark started, which suggests to me a PSU issue, but since then running that benchmark hasn't caused a restart. The BIOS and all other drivers are updated and so too is windows.

 

Things I have noticed:

 

• When I boot the sound for a USB being plugged/unplugged plays
• Similar to the above, I have had to unplug then plug my mouse in as sometimes it doesn't power it (uninstalled drivers?)
• My PC has uninstalled CS:GO randomly
• Temperatures are good
• No noticeable perfromance decrease since the issue has begun
• Once it reboots, sometimes it does it again, very shortly afterwards (< 2mins) with nothing open
• Towards the start of the issue I made Windows not reboot with errors, within an hour I got a error message never seen before about unable to save a theme, this has never reoccured

 

I think that is all, sorry for the length, I just had to get all of the above in.

 

Thanks for reading and any help given, it's appreciated

Maybe your HDD/SSD is dying?

PSU malfunction?

PSU is dying. Contact Corsair.

I think that maybe the case, however, the build is about 4 years old, so I doubt they will do much.

 

Thanks

You can get 3 years of support from Corsair and they have lifetime tech support.

Hey all; Here comes the late update.

 

I received a new PSU from corsair and upon fitting... the issue has not been resolved.

It restarted and then when back from the restart it would restart again, it then flashed a message with white text on a black background which I think contained the word 'phase'. Afterwards it reboot in to a blue windows recovery screen, but, before I could click on anything it would restart again and after that it would reboot before continually so that the motherboard flash screen couldn't even appear.

 

Anymore ideas..? Thanks
