Random pc reboot no bsod

[Freeze_O]

Hi folks,

 

My system is randomly rebooting. Can’t figure this one out. No BSOD’s

 

About 9 months ago I upgraded my system. Bought a new GTX1660Ti  a 2nd hand Gigabyte Z77P-D3 motherboard to fit my i7 3rd gen ivy bridge. Fitted the cpu with a dark rock pro cooler. Added 2x 8GB ram sticks from Hyperx. Lastly to power the rig a new PSU: https://m.alternate.nl/Cooler-Master/MWE-450Watt-Bronze-v2-voeding/html/product/1551849

 

Running a win7 install that’s probably 6-7 years old and upgraded it to win10 i think about 1-2 years ago. Then bought this Gigabyte motherboard to fit my GTX1660Ti and had to go through the hassle of migrating windows to a new motherboard. That was last Christmas break.

 

So for 8 months everything was fine and dandy but since a month things are awkward. The system operated fine, but after about an hour or so the screen goes black, the audio continues for 3 more seconds and the system then reboot. 

 

What i have done so far.

Did a mem test, all good on the RAM

Checked the voltage on the 12V rail and it was between 12.04 - 12.07 whilst running a benchmark load for about 15 min. 

 

Formatted an additional SSD which was 98% full, not the windows drive. Thinking it perhaps used it as Cache?? Not sure. It did speed up the boot process, but didn’t resolve the reboots.

 

Updated my GPU driver last week, 

Updated Windows to 2005 built about a month ago. I think there may be a correlation there. Got rid of AVG virus scanner and am running the free trial of bitdefender at the moment.

 

Just today I had another reboot after about an hour again. It feels like it’s right around the same time it happens. I checked the event scheduler and deleted a couple of old stuff like update check of AVG. didn’t do the trick either. 

 

I dont know how to:

•check the CPU

•Check other voltages

•If my motherboard may have issues

 

Any other thought or info you need to make sense of this? 

 

All the help is really appreciated

Thanks

I think the PSU might be under power/quality, A clean version of windows is recommended, since you did some migrations that aren't considered "good health" for a OS.

 

Things you can do:

- Install Windows, clean.

- Look (physical) for blown capacitor on the motherboard

- Download HWinfo (for the rails voltaje) and OCCT (for CPU/VRAM/PSU testing),

- Memtest86(+) for memory testing (only two I trust),

- Uninstall AVG and go for avira, bit defender o windows defender,

- Update BIOS

- Update Drivers (Snappy Driver Installer, driver easy, etc)

- Clean the OS with Cleanmgr+ (if didn't format)

Hi Ma__ga,

 

Thanks for the response. I downloaded the OCCT and did various load tests. The memory test crashed within 5 seconds. There's no report or anything. 

 

Not sure what to make of it. it's newly bought RAM (10 months in use now) 

the memtest86 didn't  report any errors... 

 

I have yet to do investigate the other things, but thought this may be a lead.

did another stress test in OCCT ramping up my RAM to about max. didn't crash the system (See below screencapture)

 

Tested with a single RAM stick, same crash in 3 seconds.

tested the other stick only, same thing. 

 

I also looked in the windows event viewer to see if there was anything sketchy there. It seems there are some DCOM warnings and errors.

things like Server {354FF91B-5E49-4BDC-A8E6-1CB6C6877182}  didn't register with DCOM in time.

 

Ran bitdefender virusscanner, didn't find anything

ram malwarebytes. it found 10 things, 3 of which it said were malware, 7 were suspicious. Quaranteened all of them. 

Still had a reboot yesterday whilst playing GTA V for 10 minutes. 

 

I installed HWinfo, but what should I be looking at/for?

I just did the window 10 factory reset, cleared and formatted my other two drives. Installed bitdefender (paid subscription) , installed steam, tried to install GTA V and as soon as the download started, it rebooted on me again. so my guess is it’s hardware related. 
 

Kernel-power Id41 error in the event log. I hooked up a volt meter and 12v is stabile between 12.06-12.09V 

5v between 5.10-5.12v on a molex connector. So I assume my PSU is fine?

 

I dug around in the log, and notice some odd message about harddrives beeing ok where my C-drive and E - drive seem to checking put okay. But my F drive is not specificallt being called as F but rather a strange clickable link is show in the event log. Though the drive is stated to be OK, no action required. 

Can a hard drive send my pc into a reboot even if there’s nothing on the drive?
