Ok back with a fresh problem, not sure if this is the correct place to post this as i do not have a BSOD with the crash, just a straight re boot. I read that it is likely to be a psu thing, is there any way to verify this at all, i have also heard it can be a ram thing, and i have just had a ram issue that leads me towards that too. I was having this crash during gaming, it just started a week or 2 ago, after one of the reboots i decided to check cables and connectors just to make a visual check all was ok. Upon restarting the computer it would not re boot at all, had fans and lights but nothing more. I took it to a shop as i could not find anything myself, the guy there when i returned said i had dirty ram connectors he cleaned them and away it went. Whilst there i got him to apply new thermal paste, this lowered my temps about 5 degrees so good job on that. Two days no problem and then just now rebooted again. I have just run a prime and furmark stress test together at the same time and i got a reboot. can anyone tell me what that might mean? Is it a ram or PSU or Motherboard scenario? I have no crash reports it is just a clean reboot. Appreciate some wisdom on this if poss please. The computer is running fine for normal non heavy load use. There is no overclocking on anything at all.
Many thanks Mike.

Re: Computer rebooting during gaming no crash reports

Firstly, what are your temps while gaming? If they are okay I'd start with this:
Have you run Memtest86+ 8 passes per RAM stick, one RAM stick at a time?
If that's okay, I'd try swapping out the PSU for something better just to test.
 
Re: Computer rebooting during gaming no crash reports

Got the memtest planned for overnight and day time tomorrow, now being my evening. Temps are ok all below 70 being the peak shown but running at low 60- to high 50, tropical location :) so a little higher than nice but not reboot temps, monitoring them constantly. I do not have a spare PSU and i doubt i can find anyone with a 750w to borrow, even the shops here do not stock that high, so before ordering / buying one i kind of want to try to get some help ruling out anything else. As i stated i can reproduce the reboot by running prime and fumark together at same time which would be more of a power issue than ram??? < that's a question.
 
Re: Computer rebooting during gaming no crash reports

Shops here in Croatia use that method to test the PSU. If you like, you can download OCCT and run its PSU test, if the PC reboots, I'm pretty sure it's the PSU. But be sure to test the RAM as well.
 
Re: Computer rebooting during gaming no crash reports

memtest ran for 9 hours + with 5 passes, would have run longer but somehow i stopped it when i plugged my laptop in this morning and used the wrong keyboard lol... So 5 passes no errors, can i assume that ram is less likely to be the problem and should i focus on psu as main suspect in an experts opinion please? Is there any other part that can cause the reboot situation, given that i reproduced it running prime and furmark at same time??
 
Re: Computer rebooting during gaming no crash reports

5 passes is not considered conclusive, and therefore I cannot comfortably say that RAM is not the problem.
Have you tried running OCCT Power Supply test? I believe that this will also crash the system.
 
Re: Computer rebooting during gaming no crash reports

ran memtest again today and overnight for 8 passes still no errors. OCCT i will run in a bit. Hmmm cant seem to get OCCT to start the PSU or the GPU tests, it will run a cpu test but as soon as i click start it stops it saying user stopped.
 
Re: Computer rebooting during gaming no crash reports

No oc of any kind as mentioned in op, and this is a new situation happening on a comp that is 18 months old, nothing new was added or changed except a driver update to my knowledge, and i duu that driver and loaded the previous to make sure it was not that.
 
Re: Computer rebooting during gaming no crash reports

OK, try running Unigine Superposition benchmark on the settings you usually use while gaming and let me know. That's a bit more modern test.
 
Re: Computer rebooting during gaming no crash reports

I can only run benchmark in that program it is a pay to use for stress testing, so i set it to max benchtest and it ran that with no faults avg fps of 16.50 and a gpu temp of 68 degrees at 100% gpu use so even though this is not a stress test it did push it more than i have it in game situation. It is 7 am here in sunny Thailand and getting ready for work not much i can do in my time right now. Thanks for the help so far, keep at it its appreciated :)
 
Re: Computer rebooting during gaming no crash reports

Running it on high rather than extreme as that was what u asked i got a fps 42.57 avg at 68 degree max again at 99% gpu use
 
Re: Computer rebooting during gaming no crash reports

No it has not occured in farming sim 17 which is the least demanding of games i have, it has happened in Dark n light, which is ea game and in car mecahnic 2018 which is a bit of a mess itself, but also in fractured space which i have had for years. It has not happened for last 2 days during CMS 2018 which is the game it first started doing this reset in. Temps outside have dropped a bit the last few days so maybe the cpu gpu are not having to draw as much power to keep cool?? I have not tried it in dark and light as i was in a dodgey situation and was hoping to to get killed by losing power if i logged in again lol. It was happening more frequently before i had ram cleaned and cpu re set with new paste, but as i say the temps on cpu and gpu are not in the reboot area at all. Is it poss the a UPS to not be able to pass enough power through itself if underload without tripping anything UPSish???(just a thought). I will fire up DnL again tonight see if i can get it to reboot again in that, but CMS 2018 was the game causing it the most, but this is getting patches a lot so it is slowly getting less demanding. I believe it is only the full poser pulls that are doing it as the prime 95 and furmark at same time kind of verified in my non expert mind .
 
Re: Computer rebooting during gaming no crash reports

I can confirm it's not CMS because I have been playing it since day one for like 10 hs a day and haven't had a single crash.
I'd suspect either a thermal issue or a power issue. Have you run Prime95?
 
Re: Computer rebooting during gaming no crash reports

for a 20 min period yes, my temps are lower than they were as i have re applied the thermal paste to rule that out so i do not think it is a thermal error. I do feel it is more a psu situation than a cpu or gpu but i am no expert at all and no access to one in my town, hence online assitence needed and appreciated. Gpu sat at 80 degrees and just stayed there, cpu got up to high 80's at part of the test but mostly around the high 60 - 70 area given ambient temps here are 35 degrees day time right now. Out of time here got to dash to work :)
 
Re: Computer rebooting during gaming no crash reports

I have an idea.
Would you please use MSI Afterburner and turn the OSD on while playing, so you have your stats (temp, fan speed, FPS and such) on screen while playing?
 
Re: Computer rebooting during gaming no crash reports

Ok i have a small problem with this... i have had no reboot in the last 5 days.. Bit tricky testing anything when the problem has stopped, no idea why it has suddenly stopped doing it but until it starts again so i can track it down i am left really clutching straws with nothing to hold them against the only thing i have done that may have any connection at all was a removal of some malware that came with a driver updating program ( yea i know) that i removed without using it. The malware is
[h=1]Pup.Optional.TweakBit no idea if this has anything to do with my issue or not but it is the only thing i have actually removed since the situation last happened.[/h]I would suggest we put this issue aside for now until it resarts occuring as trying to track down something not happening is next to imposs. Thanks for your help so far and i will re-post here if i get any reboots happening again( probably today now i said its stopped). I will also try the MSI prog in game if i do restart first :) I do of course fully understand it has only just stopped to lull me into a false sense of security and will start again as soon as i feel good about my comp again!!!
 
Re: Computer rebooting during gaming no crash reports

As you wish, and no, this PUP couldn't have been the cause. This was just something bundled with the driver updating program which was detected.
 
Re: Computer rebooting during gaming no crash reports

Ok started again today, during CMS 18, i have had 5 days free of this problem with heavy playing acrosss all games i own then all of a sudden back to rebooting? I have msi installed and was monitoring gpu power and temp both were at 58% and 58 degrees when rebooted. Is there anything else you want me to check with OSD?
