Windows 7: PC reboots while gaming

PC reboots while gaming

Hi Guys,

I have recently assembled a new PC and it has been rebooting while playing games. Tested with Assassin's Creed Unity and Dragon Age Inquisition.
It runs for a couple of hours of gaming before rebooting. I have disabled Automatic Restart under Startup and Recovery but haven't seen a Blue Screen. The system simply reboots.
Attached are the dumps per BSOD posting instructions.

Processor: Intel Core i5 4440
Motherboard: MSI Gaming 3
PSU: Corsair VX450W
RAM: Corsair Vengeance 8GB
HDD: Seagate Barracuda 200GB
SSD: Samsung 840 Evo 120GB
GPU: Zotac GeForce GTX 750Ti

Initially I was set up with two 8GB sticks. I ran memtest and saw errors on one of the sticks so I'm currently running a single 8Gb stick in the DIMM 2 slot
I've tried running FurMark and the GPU temp goes upto 75C and stays constant

If someone can take a look and help me figure out what could be causing the reboot I would really appreciate it.
Do let me know if there are any other logs I can provide to help with troubleshooting.

Thank you

OK, let me start by saying that this is a UBI game, or in other words... the worse console ports ever to be launched to the public and as such, full of bugs and glitches, unoptimized code, etc, etc, etc.

Being said that... are you running their latest patch?

Have you tried updating your Video and Audio Drivers?

Sorry, I don't look at zip files, not so much for potential viruses but, more importantly, because I am not going to understand them so why bother LOL.

About the best tip I can give you is... Go to UBI Dedicate forum for that game and see what the others are saying about it and perhaps there will be an easy solution to your problem.

Good Luck

Thanks for the tip, agreed on the UBI title but I'm facing the same problem with Dragon Age Inquisition
Both games run very smoothly but after a couple hours the system reboots

Audio, video, bios, chip set, almost all drivers have been updated.

I hope someone looks into the zip file. I'm just following thread rules

Please ignore any typos, I'm on my phone.

Usually with a hardware issue, such as RAM, you'll get a BSOD. Or errors in a test.

If it just shuts down without any error or warning at all, it could be a heat issue.
But most likely a power supply issue.

It looks like you may have a bad stick of RAM if its failing a test. But that shouldn't cause a shut down. Or at least I don't think so.
It would cause errors, a game to crash or a shutdown via BSOD though.

I agree the PSU looks a Bit weak for what your running i would go 550 watt 450 looks like you are really taxing it

Thanks guys. Is there a way to narrow down that my PSU is the issue? Maybe some diagnostic tools.

Also, I'm not using the bad RAM stick. Only the one that passed memtest

My max temps from speedfan are below
GPU : 72
Core 1: 58-60
Core 2: 58-60
Core 3: 58-59
Core 4: 57-59

I see the thread was moved from BSOD subforum to gaming so I guess the zip file I provided won't be checked.

Let me know if there's anything else that could help

In regards to testing, without needing special equipment, you are quite limited.

Technically I think you have enough power. As A 750ti needs a 300W system but .... and a PSu calculator says a 300W is enough with the equipment listed in the first post but... those numbers are kinda generic.
It all depends on how good of power the PSU puts out. And though Corsair is typically good, I don't really know anything about the one you have. I would think you're probably pretty close though.

But those symptoms scream PSU failure to me.

You have a couple options:

1) Try a bit beefier PSU as a test. Do know anyone who may have an extra laying around? a 500-550W one perhaps? Swap it out and test.

2) Run a CPU/RAM stress test to make sure everything is stable there. It seems you ran a memory test, but thats a bit different from a stress test.
Next a GPU stress test to know its stable

When these components get under stress could be the cause of the shut down.

I would try the stress tests first, and make sure everything is stable, and set properly. if its shutting down mid test with no errors, dowble check all connections then move to testing a different PSU.

Appreciate the response Wishmaster!

I will try a prime95 run to see if it restarts. Any idea how long I should run this? I'm thinking overnight might be overkill
I have run FurMark for an hour with no reboots but I'm not sure if that is long enough to stress test the GPU

The PSU is old, 5 years I think, not sure how much the power output might have degraded. I do not have a higher Watt PSU available, might go ahead and buy one anyway.

They do degrade overtime.

I would say if you survive 45minutes - 1hour of Prime you should be fine. Sure, there are instances when some issues wont show up until a few hours in (Ive seen them show at 8hrs in),
but if its a major stability issue or a insufficient power issue, I would think that would show up in an hour or less. Most major issues show themselves pretty fast.

Remember too, keep a close eye on the temps. Heat may be a cause as well and just overlooked so far.

This might sound strange but is the north bridge properly ventilated?
If you don,t have another psu maybe disconnect an unused optical. Ihad a psu with a bad molex connector while back it caused a short of sorts.
