I have had my computer for about 6 months with no trouble. Recently I have been getting a blue screen and I cannot figure out why. There is no pattern as to why. Sometimes I can work for hours and I won't get any errors. Other times I will turn my computer on and I will get a blue screen.

What I know so far, although I may be wrong:
• PSU is good
• No RAM errors
• CPU seems to be good

OP: Windows 8.1 Pro
MB: MSI MS-7751
CPU: Intel i7-3770K 3.5
RAM: Patriot Viper 3 16GB DDR3
GPU: NVIDIA GeForce GTX 660
PSU: Antec HCG-750 750W 80 PLUS Bronze certified

What should I be checking that could be the cause?

Could dust be a culprit?

So I cleaned out all dust a few hours ago. Crashed 2 times since then so probably not the issue.


Some more info, computer temp is in the 25-35 C* range. I don't know what else I can check. Any ideas what else may be the issue?

Thanks, will do. Except for now a dmp has not been created. I was following a tutorial on how to make sure a dmp is created and found out the page file was set to small. I hope it will create a dmp next time but I can't say when that will be. As I mentioned the crashes are random and quiet sporadic.

Anyways if a dmp is created next time it crashes I will post it here.

Also is the randomness a sign that the issue is not hardware?

The failure profile of most hardware is that the failures are generally within the first 30 hours of operation.
then a year later as cheap fans tend to wear out, then the spinning hard drive start to give errors until you start to get general electronics parts to fail (3 to 5 years).

I would say, in general after your hardware is properly setup and done with its "burn in period"
You get software errors, most of them in the device drivers.
About 95 % of the bugged drivers are 3rd party drivers that Microsoft does not distribute. This is not a reflection of how great Microsoft is at creating drivers but reflects that a Microsoft driver is updated directly by Windows update while a third party driver requires you to figure out the problem and locate the proper update and install it yourself. Basically if several million machines hit a bug in a microsoft driver they get several million automatic windows error reports and some poor SOB at microsoft has a bad day until they roll out a fix via the windows update.

Thanks, that was very informative. It crashed again a few times, the first was a complete dmp at 15 gb so I got a smaller dump at about 600mb. Let me know if that is enough to find the error. Oddly enough I did notice the crashes happened after I ran uTorrent had been running for a little while.

I also got driver_irql_nor_less_or_equal(netio.sys) on the blue screen.

ok your system broke in some networking functions: My first question is do you really want to be running a special software network router and crappy network capture softare? Or is your system infected via malware? (hijacked)

do you really want to be running
Image path: \SystemRoot\system32\drivers\npf.sys
Image name: npf.sys Fri Jun 25 09:50:58 2010
Part of the WinPcap packet capture library. This file can be installed by malware but is not considered harmful to your computer.

I would run a malwarebytes scan and remove any malware. If you intend to run the various software routers, and capture drivers let me know and I will look at the memory dump again. Otherwise it just looks like a malware infection
iSafeNetFilter.sys is sometimes listed as a "unwanted" or trojan

So I ran a malwarebytes quick scan and it removed some things. Only a quickscan, I'll run a fullscan. Would malware bytes remove the network router software. The only idea I have about the WinPcap packet is that it might have come with an unused wireless card I have installed. If that is the case it is pretty useless to me.

Is iSafeNetFilet.sys causing problems? I think it's part of a programmed I installed called Yet Another Cleaner. Nothing I really use so I wouldn't mind removing it at all, may do so anyway just to clean up a bit. .

you will really want to uninstall that software, the capture software can be used by malware to capture your network traffic, filter it and send it on to unknown sites. The software router on you machine can be used to route you to fake sites designed to get your username and password. Having the virus scanner can block other scanner from running. I would uninstall or restore my system to a known good state. I would also change my passwords on any online accounts I have been using. I did not actually see a problem with the iSafeNetFilter.sys It was just listed as a trojan and I figure most people don't want to allow unknown people to use their machines remotely.
It may be a legit program, you will need to confirm you want to run it.
