Windows 7: Computer freezes randomly

Computer freezes randomly

Hello, i originally created a thread like this is BSOD section but thought it would be better suited here.

I've had this issue for a couple of months now, but in the latest 1-2 weeks it has gotten pretty severe. I have no idea how to bugtest this, so any pointers would be really appreciated.

When the computer freezes, it can happen in two different ways, either the monitor goes pitch black and the computer restarts itself, or the screen just freezes (any music freezes and makes a static sound) and you need to hard reboot it. These crashes can happen any time.

Something i've noticed is when i power on the computer for the first time in the day, i usually start the game DOTA2 and just let it idle for a bit. The computer will usually freeze withing 5-10 minutes, and i will do a hard reboot. The next time i open DOTA2 after the hard reboot, the game can run for a couple of hours without crashing or freezing. Although this is usually a hit and miss, sometimes when a crash has happened and i reboot, several more crashes can keep happening in a row and ill have to keep doing hard reboots.

Today it happened again, and this time when i rebooted, the computer actually completely froze on the startup screen that lets you go to BIOS.

Looking at the eventlogger, the Critical one is the regular ID 41 "computer didnt shut of correctly". There are then a total of 9 errors (3 errors from 3 different ones) that are logged about 30-60 seconds after the Critical one, and they have the following ID:

ID 102 PNRPSvc
ID 7001 Service Control Manager
ID 7023 Service Control Manager

As far as im concerned, the temps all seem to be below 40C, and during load it doesnt go above 55-60C


I've cleaned most of the case with compressed air i believe, but not each piece individually. I've also run a chkdsk but couldn't figure out where to look for wrong info.

My GPU is a Geforce GTX 750 SC(super clocked from factory) if that makes any difference.

The only thing that i can think of doing right now is run a memtest, which i was gonna do today and let it run overnight. I'm wondering however if i should be using memtest86 or memtest86+.

Any help is appreciated, Thank you!
Gabriel

You need to look at the errors before "the computer did not shut down properly". That message is there becasue you forced a shutdown so the freezing happened before that.

Hey cyanna,

There are no errors before the critical one, atleast not within the latest hour in the event logger. The only time errors show up in the event logger is when the PC has a force shutdown, and it's always the same 3(total 9) errors.

Hi Gabriel,
The minimum RAM for that game is 4GB, so i would suggest you get more.
Dont forget when you start W7 theres a lot of process's vying for resources.

Hey torchwood,

I understand the minimum RAM for the game is 4GB, but i've been playing the game since 2011 with this computer, only to replace the GPU once. I've not had this kind of problem before untill a couple of months ago when it actually started. Back then i didnt mind it too much cause it happened maybe once a month, but this past week it has been happening everyday, sometimes 3-5 times a day.

There are days when i don't start DOTA2 at all, but the PC will still freeze randomly.

Something I noticed from the picture in Post #1

Your ram is running in single channel.
Your motherboard in dual channel capable.

GIGABYTE - Motherboard - Socket AM3 - GA-890GPA-UD3H (rev. 2.1)



Quote:
  1. 4 x 1.5V DDR3 DIMM sockets supporting up to 16 GB of system memory (Note 1)
  2. Dual channel memory architecture
  3. Support for DDR3 2000(OC)/1333/1066 MHz memory modules
This may or may not cause a problem.

Exactly what ram do you have and what slots are they installed in?

Thanks, the info is in swedish so im not sure if linking anything here is useful, however im guessing the small bit that's important is "0 kB in damaged/bad sector".

i will run a scannow now.

EDIT: Nothing found

This actually came as a shock to me aswell when i looked at the picture.

the RAM im using is "Corsair 4GB (2x2048MB) 1600MHz XMS3" and the motherboard looks like this
Theres 1 stick in the first blue and 1 stick in the first white. I must be crazy because i could of sworn it used to be blue white blue white, and not blue blue white white, have i mixed up how to do dual channel?

Break out your motherboard manual and verify the proper slots for your ram.

It appears that Speccy is seeing all your ram but they are in the wrong slots.
This may or may not be your total problem. Many times their is more than one problem.

So if i understand this correctly, the RAM should be next to each other in the blue slots? i got a bit confused by the channels being even and odd numbers
